Summary:
Previously 'arc diff X' with mercurial meant to use X as the base
to diff against. Now it means use gca(X,working directory) as the base to
diff against. This matches the git behavior.
Test Plan:
Ran 'arc diff master' on a repo where master was ahead of the feature branch.
Verified that the diff result included only the diffs in the feature branch.

Summary:
arc diff on large mercurial repos was taking 14 seconds just to get
to the commit message prompt. With these optimizations it takes 4.
- "ancestor(.) - ancestor(XYZ)" is expensive because it has to build the
entire 400000+ revision history for both. "XYZ::. - XYZ" is much cheaper
because it only looks at the revisions between XYZ and the working directory.
- "hg outgoing" has to talk to the server, which is slow. "hg log -r draft()"
gives us the same information and is much cheaper. We fall back to 'outgoing'
on older versions of mercurial.
Of the remaining 4 seconds, 2.5 are spent in 'hg status', which is a bit harder
improve.
Test Plan: Ran arc diff on our hg repo. Verified it ran faster and the diff was created.

We assume `git` is available now, but should not. Specifically, if a user runs a working copy operation like `arc list` in an SVN working copy without `git` available, they get this error: P707
We interpret git errors very narrowly; be more liberal in how we interpret them. This assumes users working with `git` will have a functional `git`, but this seems like a reasonable assumption and lets us remove some error text matching code.

A git submodule looks a lot like a normal git repo, but the .git

location of the git directory. When arcanist tries to write a file into
a directory inside of there, it was failing silently, and then crashing
silently when it couldn't read results back out. Instead of assuming the

Summary:
See D4049, D4096.
- Move commit range storage from Mercurial and Git APIs to the base API.
- Move caching up to the base level.
- Store symbolic name and resolved name separately, so we can re-resolve the correct commit from the symbolic name after dirtying caches.
- Rename `supportsRelativeLocalCommit()` to `supportsCommitRanges()` (old name wasn't very good, and not consistent with new terminology like the `--base` flag).
- Rename `getRelativeCommit()` and `setRelativeCommit()` to `getBaseCommit()` and `setBaseCommit()`.
- Introduce `reloadCommitRange()` and call it from `reloadWorkingCopy()`.
I think this fixes the problem in D4049, and provides a general solution for the class of problems we're running into here, with D4096. Specifically:
- We no longer get dirty caches, as long as you call reloadWorkingCopy() after changing the working copy (or call a method which calls it for you).
- We no longer get order-of-parsing-things problems, because setBaseCommit() reloads the appropriate caches.
- We no longer get nasty effects from calling `requireCleanWorkingCopy()` too early.
Test Plan: This is pretty far-reaching and hard to test. Unit tests; ran various arc commands. :/

# For "amend", to set the range to the commit to be amended (also 'HEAD^' or '.^').
# For "patch" and "upgrade" so we don't fail just because there's an invalid "base" rule somewhere in the config when doing clean-working-copy tests.
For cases (1) and (2), introduce an "arc:this" rule to mean "the current commit". For case (3), remove the call; it is no longer necessary to check the commit range in order to do tests for the working copy state after D4095.

Summary:
See discussion in D4049.
The getWorkingCopyStatus() method gets called from requireCleanWorkingCopy() in a lot of places, which triggers resolution of the base of the commit range. This is unnecessary; we do not need to examine the base commit in order to determine whether the working copy is dirty or not. This causes problems, in D4049 and elsewhere (we currently have a lot of fluff calls to setDefaultBaseCommit() in workflows which need to call requireCleanWorkingCopy() but do not ever use commit ranges, such as `arc patch`). This is mostly an artifact of SVN, where the "commit range" and "uncommitted stuff in the working copy" are always the same.
- Split the method into two status methods: getUncommittedStatus() (uncommitted stuff in the working copy, required by requireCleanWorkingCopy()) and getCommitRangeStatus() (committed stuff in the commit range).
- Lift caching out of the implementations into the base class.
- Dirty the cache after we commit.
This doesn't do anything useful on its own and creates one caching problem (`commitRangeStatusCache` is not invalidated when the commit range changes because of `setBaseCommit()` or similar) but I wanted to break things apart here. I won't land it until there's a more complete picture.
This creates a minor performance regression in git and hg (we run less stuff in parallel than previously) but all the commands should be disk-bound anyway and the regression should be minor. It prevents a larger regression in `hg` in D4049, and lets us do less work to arrive at common error states (dirty working copy). We can examine perf at the end of this change sequence.
Test Plan: Ran unit tests, various `arc` commands.

Makes arc land support hg repositories. Both bookmarks and named branches can be landed. For the most part all the arc land options work, but there are a few caveats:
- bookmarks can only be landed on bookmarks
- branches can only be landed on branches
- landing a named branch with --merge creates a commit to close the branch before the merge.
- since mercurial doesn't start with a default master bookmark, landing a bookmark requires specifying --onto or setting arc.land.onto.default
Test Plan:
Tested arc land with all permutations of --merge, --keep-branch on both bookmark branches and named branches. Also tested --hold, --revision, --onto, --remote.

This is horrible and git specific, but fixes a case where people are using "arc
patch --nobranch ..." when they're not currently on a branch.
The old code assumed you were on a branch and used getBranchName() to record
this, in order to return to that branch later and cherry-pick the patch.
When not on a branch, and using arc patch --nobranch, this was trying to return
to the branch '(no branch)'.
Now, I detect that we're not on a branch and just record what HEAD is instead.

Checkout the SHA of master (so I'm on master, but not on a branch) then try to
patch it with a feature diff:

- When you diff only working copy changes, we currently incorrectly identify all your open revisions as belonging to the working copy. Instead, correctly identify none of them as belonging to the working copy (in theory, we could go farther than this and do path-based identification like SVN, but with --amend in hg 2.2+ this workflow should be going away in the long run).

- Fix a bunch of Mercurial stuff:
- Our use of '.' is wrong, and based on a misunderstanding on my part of the behavior of `hg diff --rev . --rev .`, which means "ignore the second --rev flag", not ". means working directory state". As far as I know there's no explicit way to say "the working copy plus all its changes".
- The `--prune` argument to "hg log" does not support symbolic names like ".^". Use revsets instead.
- Reduce the number of times we need to run `hg branch`.
- We can safely use "." to mean "the working copy revision", and do not need to do "hg --debug id" or similar.
- Generally simplify some of the nonsense in the implementation left over from me having no idea how Mercurial works.

Summary:
New optional mode. If you set 'base' in local, project or global config or pass '--base' to 'arc diff' or 'arc which', it switches to DSL mode.
In DSL mode, lists of rules from args, local, project and global config are resolved, in that order. Rules can manipulate the rule machine or resolve into actual commits. Provides support for some 'arc' rules (mostly machine manipulation) and 'git' rules (symbolic ref and merge-base).
Test Plan:
Ran unit tests. Also:
```$ arc which --show-base --base 'arc:prompt'
Against which commit? HEAD
HEAD
$ arc which --show-base --base 'git:HEAD'
HEAD
$ arc which --show-base --base 'git:fake'
Usage Exception: None of the rules in your 'base' configuration matched a valid commit. Adjust rules or specify which commit you want to use explicitly.
$ arc which --show-base --base 'git:origin/master'
origin/master
$ arc which --show-base --base 'git:upstream'
Usage Exception: None of the rules in your 'base' configuration matched a valid commit. Adjust rules or specify which commit you want to use explicitly.
$ arc which --show-base --base 'literal:derp'
derp
$ arc which --show-base --base 'arc:halt'
Usage Exception: None of the rules in your 'base' configuration matched a valid commit. Adjust rules or specify which commit you want to use explicitly.
$ arc set-config --local base git:origin/master
Set key 'base' = 'git:origin/master' in local config.

Summary:
Using .arc as the scratch and per-repository configuration directory
has some unfortunate consequenses in the real world. Among other
things, people forget to .gitignore it so it gets checked in.
Test Plan:
the only thing that seems to use this is the relative commit setting
for git. This diff consists of 2 commits, one for the .gitignore and
one for everything else.
Comment out the portion of my .git/config that defines the upstream
for the branch. Run arc diff --only with HEAD^ in
.arc/default-relative-commit. See that .gitignore is not included in
the resultant diff, that .arc no longer exists, and that .git/arc
exists and has HEAD^ in .git/arc/default-relative-commit.

Summary:
This adds basic support for mutable history for arc diff and arc amend for
mercurial. This is purely opt-in (so it shouldn't affect anyone who doesn't want
this feature) by explicitly setting
"immutable_history" : false
in arc configuration.
This also fixes another instance of weird behaviour for multiple heads - the
first instance was fixed here:
https://github.com/facebook/arcanist/pull/28
Test Plan:

When ##arc diff## produces an update diff, it should list only commits that are
ancestors of the current revision - not ones from other heads.

Summary:
- When you run "arc diff" in Mercurial, we currently give you an empty template. Instead, prefill a likely template by parsing messages, as we do for Git.
- Unify Git and Mercurial logic for acquiring messages, since `getLocalCommitInformation()` now provides this information. This should improve Git performance, and allows us to delete some code.
- Merge messages more intelligently. Currently, we just overwrite fields. Instead, merge arrays (like ccs, reviewers, tasks) and concatenate strings (like summary and test plan). We need to special case "title", see inline.
- @csilvers: this is a precursor to implementing "--reviewers", etc.

Summary:

Although this patch is dumb, it's certinaly safe, and can only do something wrong if the user has environmental variables like H, P, T, or x01, in which case they're sort of asking for it.
