Summary:
Add variable names (`$varname` in `@param type $varname explanation`) to PHPDoc method headers, for fun and profit.
Closes T15923
Test Plan:
* Read the method signatures and their corresponding PHPDoc headers at your fireplace
* Still run `./bin/diviner generate` without explosions (though it is very lenient anyway?)

I suppose I missed these cases.
Test Plan:
- I ran `arc land --test` and verified the rebase used by `ArcanistMercurialLandEngine` was run with the flag to enable the extension.
```
$ hg --encoding utf-8 --config 'extensions.rebase=' rebase --dest 2fd68f4c48aaab9f6d5613b90e60b8219a9af0ae --rev 6132da63090c2c8a8d479aaae7b20497dda3e8fd..6132da63090c2c8a8d479aaae7b20497dda3e8fd --logfile - --keep --collapse
```
- I modified the merging to throw an exception before writing to the future's stdin and verified that after `arc` completed there was no rebase active.
- I set up 3 dependent diffs and landed the middle revision and verified the first and second revisions landed but not the tip revision and there were no errors and the resulting working directory was correct.

Summary:
Currently there are a number of `--config extensions.blah=` sprinkled throughout the Mercurial APIs which aren't pleasant to look at. Additionally it turns out the `rebase` command requires the `rebase` extension which is not turned on by default. Uses of `rebase` should also be including this flag to enable the extension when it's in use.
This adds `ArcanistMercurialAPI::buildMercurialExtensionCommand()` which allows running a Mercurial command that requires an extension just by naming the extension instead of providing the full `--config..` argument.
It can be used e.g.
```lang=php
$api->execxLocalWithExtension(
'strip',
'strip --rev %s --',
$rev);
$api->execxLocalWithExtension(
'arc-hg',
'arc-amend --logfile %s',
$tmp_file);
```
Which produces
```lang=console
$ hg --encoding utf-8 --config 'extensions.strip=' strip --rev 82567759e2d703e1e0497f5f41363de3a1500188 --

Test Plan: I ran through several scenarios of running `arc diff` and `arc land` with uncommitted changes on non-head commits, while not having the `evolve` extension enabled. Using the `--trace` argument I verified that `rebase`, `strip`, `arc-amend`, and `arc-ls-markers` were all invoked and the corresponding `arc diff` and `arc land` commands succeeded. I also ran `arc land --onto-remote default` while `arc-hg.py` raised an exception for the "remote" case and verified that the error was caught by Arcanist and displayed the error and prevented further execution. I removed the error from `arc-hg.py` and re-ran the command and verified it succeeded.

Summary:
After `arc diff` creates a revision in Phabricator it amends the commit to include a link to the revision in the commit message. For Mercurial this is done with `hg commit --amend --logfile` however this will fail when trying to create a diff for a non-head commit.
This updates `ArcanistMercurialAPI::amendCommit()` to allow amending a non-head commit in two ways, depending on whether `evolve` is in use:
No evolve:
1. Rebasing the current commit onto the current commit's parent, using the new commit message
2. Rebasing all children + descendants of the current commit onto the new resulting commit
3. Stripping the original commit
With evolve:
1. Amend the commit with `hg amend --logfile`
2. Run `hg evolve` to tidy up all commits
Test Plan:
I created 6 commits in a row placing a bookmark at commits 2 `bookmark1`, 4 `bookmark2`, and 6 `bookmark3`, and ensured I had `arc:bookmark` in my base ruleset.
No evolve, non-head changeset:
1. I verified I did not have `evolve` enabled by running `hg debugextensions` and did not see `evolve` in the listed active extensions.
2. I updated to `bookmark1` and modified a file to leave a dirty working state.
3. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
4. I checked the status of my repository and verified it was still linear and the bookmarks pointed to the proper commits.
5. I ran `hg log -r bookmark1 --template {desc}` to view the full commit message and verified it contained both `Summary: ...` and `Differential Revision: https://...`.
6. I ran `hg diff -c bookmark1` and verified the changes for that commit included the changes I made in step 2.
No evolve, head changeset:
1. I updated to `bookmark3` which is the head commit and modified a file to leave a dirty working state.
2. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
3. I checked the status of my repository and verified it was still linear and all the bookmarks pointed to the proper commits.
4. I ran `hg log -r bookmark3 --template {desc}` to view the full commit message and verified it contained both `Summary: ...` and `Differential Revision: https://...`.
5. I ran `hg diff -c bookmar3` and verified the changes for that commit included the changes I made in step 1.
With evolve:
1. I enabled `evolve` and verified it was enabled by running `hg debugextensions` and saw `evolve` in the listed active extensions.
2. I updated to `bookmark2` and modified a file to leave a dirty working state.
3. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
4. I checked the status of my repository and verified it was still linear and all the bookmarks pointed to the proper commits.
5. I ran `hg log -r bookmark2 --template {desc}` to view the full commit message and verfieid it contained both `Summary: ...` and `Differential Revision: https://...`.
6. I ran `hg diff -c bookmark2` and verified the changes for that commit included the changes I made in step 2.

Summary:
Refs T13546
**Behavior Changes**
1. Currently, after landing the `--onto` bookmark will not be advanced to the newly pushed commit(s)
- This updates so that after pushing commits upstream, onto-marker bookmarks are pulled back from the server to retrieve their updated state
2. Currently, after landing the working directory will typically be the old `--onto` commit
- This updates the behavior in the following ways
1. If the starting working state is a commit that is part of a revision being landed, the post-land state will be the newly published commit for that revision
2. If the starting working state is a commit for a tip revision being landed and there is only a single `--onto` target, the post-land state will be the newly published commit and the `--onto` bookmark will be activated, if applicable. If there are multiple `--onto` targets defined (uncommon) then the resulting working state will be the same behavior as before, as the desired behavior for this case is ambiguous.
3. If the starting working state is a commit that is not part of any revision being landed, then the post-land state will be that same commit, activating the same previous bookmark if applicable.
**Bugs Fixed**
1. When landing a diff that includes multiple commits, where the non-tip commit adds a file and later commit modifies that file, the land process would fail during rebasing.
2. When landing, the display of what commits are going to be landed only includes the commit hash but should include part of the commit message for easy identification.
3. If errors occur during a rebase while landing, the resulting state is an in-progress rebase. Users will typically not be able to resolve this in-progress rebase and possibly confuse them further as they have to first abort the rebase before trying to clean up. These rebases will now be aborted by arcanist before exiting.
4. If using evolve, landing a non-tip revision would leave behind orphaned commits.
Test Plan:
Bookmark test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to activate `test`
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Non-bookmark test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to be the new commit, but not activate `test` even though it points to that same commit
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Not-working state test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to an older commit not related to the one being landed
- I landed that diff
- I verified the ending resulting working state was on the older commit I was on prior to landing
Multiple commits test
- Using `test` bookmark I created a commit that added a new file, made a diff, made another new commit on top of it which modified that file, then updated the diff
- I updated my working state to the first commit for the diff (non-head)
- I ran `arc land test` to land the diff
- I verified that the resulting working state was on the newly published `master` commit
Landing while on `master`
- I created a diff with a bookmark `test`, as a branch from before the `master` commit
- I updated working state to the `master` bookmark
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Landing with no local `master` bookmark
- I created a diff consisting of two commits with bookmark `test`, as a branch from before the `master` commit
- I left working state on `test` and deleted my local `master` bookmark
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit and the `master` bookmark was pulled and active
Cascading diffs while on an earlier diff changeset
- I setup two diffs, each consisting of two commits, one depending on the other
- I put the working state onto a commit from the earlier diff
- I landed the later diff
- I verified that the resulting working state was on the newly published commit associated with the earlier diff, which is not the new `master` commit so there was no active bookmark
Cascading diffs while on the later diff changeset
- I setup two diffs, each consisting of two commits, one depending on the other
- I put the working state into a commit from the later diff
- I landed the later diff
- I verified that the resulting working state was on the newly published commit for the later diff which was `master` and `master` was active
Landing a non-tip revision, with evolve
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I verified I had the evolve extension enabled via `hg debugextensions`
- I put the working state on a commit in the first revision
- I landed the second revision
- I verified that the resulting working state was clean, that revisions 1 and 2 were properly landed and published, and the resulting working state was on the published commit for the first revision.
Landing a non-tip revision, without evolve
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I verified I did not have the evolve extension enabled via `hg debugextensions`
- I put the working state on a commit in the first revision
- I landed the second revision
- I verified that the resulting working state was clean, that revisions 1 and 2 were properly landed and published, and the resulting working state was on the published commit for the first revision.
Landing a non-tip revision, while the non-landing revision is active
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I put the working state on the latest tip revision commit and its bookmark
- I landed the second revision
- I verified that revisions 1 and 2 were properly landed and published, and the resulting working state was still on the latest tip revision commit and its bookmark was active.

Summary:
Ref T13576. See that task for discussion.
When a user runs `arc land --pick A`, they may be selecting a range of commits ("X..Y") which have ancestors ("V..W") that should NOT land.
We must slice "X..Y" out of history before we can merge it, to avoid landing changes from "V..W".
When "X..Y" is simple and linear, we can rebase the range to pick our desired slice out of history.
When "X..Y" includes merge commits, we frequently can not, and I could not identify any simple alternative. The best alternative I came up with is this "reduce" operation:
- squash "into" onto Y, producing S, to guarantee there are no natural conflicts;
- squash S onto X^, producing T, to get rid of the merge commits;
- rebase T onto "into", producing R, to slice "X..Y" out of history;
- squash R onto "into", producing Q. (R and Q will be the same, but this simplies the code.)
This feels flimsy and fragile, but I can't immediately find a way to break it. See T13576 for more discussion.
Test Plan:
- Applied conflicting changes to `example.txt` in `master` and `feature1`.
- Ran `arc land`, got a merge conflict.
- Resolved the conflict with `git merge master`.
- Ran `arc land`.
- Before: merge conflict.
- After: `arc land` resolves the merge correctly.
- Stacked `feature2` on `feature1`, and made various mutations to `feature1` and `feature2`, then ran `arc land --pick feature2`. Changes made in `feature1` should not land, and they mostly do not. See T13576.

Summary:
See PHI1808. Currently, "arc land <some bookmark>" does not destroy the bookmark in Mercurial. There are three issues here:
- "hg rebase --keep --collapse" moves bookmarks to the rewritten commits;
- "hg strip" moves bookmarks backwards;
- "hg prune" moves bookmarks backwards.
To get around "hg rebase", save and restore bookmark state.
To get around "hg strip" and "hg prune", explicitly destroy bookmarks pointing at commits before we strip/prune those commits.

- Ran "arc land <some bookmark> --trace". Saw arc reset the bookmark position after rebasing, and destroy the bookmark explicitly before stripping.

Summary: Ref T13434. Since "git p4 submit" gets more complicated when submitting merges, and empty merges (as with "--no-ff") seem to vanish, and it's not clear this is desirable or useful anyway, just make the "merge" strategy an explicit error with Perforce remotes.
Test Plan: Ran "arc land --merge ..." in a Git/Perforce repository, got an explicit error. Ran "arc land --squash ...", got existing working behavior.

Summary:
Fixes T10650. It's valid to `arc land --remote origin --onto master` without first fetching that ref. If we can't find a local ref for a specified remote branch, try to fetch it before giving up.
(In the long run, this should be valid even if the remote branch does not exist at all and the user intends to create it -- see T12876 -- but this is a step toward that.)
Test Plan:
- Ran `rm .git/refs/remotes/origin/master`, then landed into "master".
- Before: "arc land" bailed out immediately.
- After: "arc land" fetches the missing ref.
```
$ arc land
TARGET Landing onto "master", the default target under git.
REMOTE Using remote "origin", the default remote under Git.
TARGET No local ref exists for branch "master" in remote "origin", attempting fetch...
FETCHED Fetched branch "master" from remote "origin".
...

Summary: Ref T13434. Move some git-engine-specific handling of "arc land" arguments into the Git engine. This prepares to handle Perforce workflows.
Test Plan: Will "arc land" this change.

Summary:
Fixes T10321. Some reasonable but less-common workflows involve running `arc land` from a detached HEAD state.
When users do this, we currently try to delete the raw hash as though it were a branch during cleanup. Instead, detect if the thing we're thinking about deleting is a branch or not, and just leave it alone if it isn't.
Test Plan:
- Ran `git checkout <some hash>`, then `arc land --revision <some revision>`.
- Before, everything worked but cleanup tried to `git branch -D <some hash>`.
- After, everything worked and cleanup skipped branch deletion.

Summary:
Fixes T11435. This isn't a perfect solution since there's a little code duplication, but a perfect solution is probably a bit more involved.
See T11435 for some discussion. In particular, most `git diff` commands already get this flag via `ArcanistGitAPI->getDiffBaseOptions()`.
Test Plan: Will land this change.

Summary:
Fixes T10314. In `arc land`, we currently run `git fetch` as a subprocess.
However, this can prevent password prompts (when fetching over HTTP with basic authentication) from working properly.
Instead, use passthru to redirect stdin/stdout to the subprocess so the user can type their password.
This adds a little extra clutter to the `arc land` output but I think that's OK.
Test Plan: See T10314, @maxie confirmed this fixes the issue.

Summary: Fixes T9973. When users run `arc land --hold`, give them the commands to move forward (push) or backward (checkout the branch/tag/commit they were on) and be explicit that branches have not changed.
Test Plan: Ran `arc land --hold`, got lots of explanatory text.
