Summary:
Recently, in D4097 or one of the precursors I refactored this. However, when $rev is null parseBaseCommitArgument() throws ("This VCS does not support commit ranges."). Shield the call so it only happens if if $rev is nonempty (we still want to make the call, so "arc lint --rev x" on SVN will throw and inform the user that "--rev" is incorrect usage).
(@vrana, this was reported by FB and might be worth pushing.)
Test Plan: Ran "arc diff --preview <path>". Grepped for other parseBaseCommitArgument() callsites and verified they don't have similar issues.

The missing piece is the starting point of the branch.
I was thinking about using `arc.land.onto.default` but we also need to get 'origin'.
This is also the last step of a simple workflow where underlying VCS is not abstracted away.

Summary:
Currently, if you run `arc` in arcanist/ or libphutil/ and your PATH and on-disk configuration are set up so a different version of arc or libphutil are the ones that actually load, we fail with an exception like "running arcanist in a different copy of arcanist is not supported".
This causes problems for Harbormaster, since we'd like to be able to run 'arc' in a copy of libphutil/ and have it execute unit tests for that copy rather than failing abruptly. So, if we detect that we're in arcanist/ or libphutil/, execute 'arc' again with the same arguments but force it to load the working copy in place of either the 'arcanist/' or the 'libphutil/' that it decided to load.
This is pretty much horrible black magic.
Test Plan: Ran 'arc list --trace' inside copies of libphutil/ and arcanist/ outside of the normal include chain. Saw it detect these, emit a message, and re-execute itself correctly.

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. :/

Summary:
This method is used in three cases:
# For unit tests, to set the range to 'HEAD^' or '.^' in an agnostic way.
# 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.
Test Plan: Ran unit tests, "arc upgrade", "arc patch", "arc amend".

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.

This changes arc land's hg support to allow you to land a branch or bookmark that has nested branches/bookmarks. Example:
// Initial state:
// -a--------b master
// \
// w--x mybranch
// \--y subbranch1
// \--z subbranch2
//
// arc land --branch mybranch --onto master :
// -a--b--wx master
// \--y subbranch1
// \--z subbranch2
Test Plan:
Created several repos like in the summary and ran 'arc land' and 'arc land --keep-branch'. Did this with both bookmarks and named branches. Scenarios tested:
- mybranch having no child commits
- mybranch having a child branch with several commits
- mybranch having two child branches
- mybranch having a child branch which has two more child branches
No code was added outside of a "if ($this->isHg)" so I didn't run git arc land.

Summary:
See chatlog from https://secure.phabricator.com/chatlog/channel/%23phabricator/?at=37257
Basically, the install's developers sometimes use "git merge master" instead of "git rebase master" to pull changes from master into their branch. When we run "git rebase master" at the end, this creates a lot of conflicts.
Instead, optionally run "git merge master". This should be equivalent in our case (where we always rebase) and much better in their case (where they sometimes merge).
We're both going to use it for a bit and see if it creates problems. If it improves the "sometimes-merge" workflow without affecting the "always rebase" workflow, we can make it a default. If it improves theirs but damages ours, we can keep it a flag/option. If it's just terrible, we can figure out something else.
Test Plan:
Ran `arc land --mergeup --trace <feature> --keep-branch --hold`, see P624 for output. Observed merge update strategy and general success.
Also verified the conflict:
$ arc land --mergeup --merge
Usage Exception: Arguments '--mergeup' and '--merge' are mutually exclusive: The --merge strategy does not update the feature branch.

Summary:
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.

Summary:
See discussion in D4056. In `findRevision()` we call `loadWorkingCopyDifferentialRevisions()`. However, this method depends upon the state of the working copy, because the end of the commit range it examines is HEAD. Prior to D4056 we checked out the target branch before calling `findRevision()`; after D4056 we call it earlier.
This isn't problematic in the `arc land` case, but in the `arc land <branch>` case it means we may fail to identify a revision, or identify the wrong revision, because HEAD isn't where we expect it to be.
Instead, unconditionally check out the target branch before finding the revision.

There is one big decision: How to get linters version.
I've created `getCacheVersion()` which is supposed to be bumped every time engine or any linter is changed.
This is not very nice but the other alternative (detect this automatically) seems worse:
- The engine may be outside repo and may or may not be under version control so getting its version through something like `git log` may not be even possible.
- If it is in the same repo then every rebase will obsolete the whole cache.
Even though bumping the version manually is PITA I still think it's a better solution.

$ time arc lint --cache 1
# verified file
$ arc arc lint --cache 1
