Summary:
FB runs some linters on background and it's a magnificent hack using `ParallelLinter` (two instances), `BackgroundLinter` and `FutureLinter`.
I want to simplify this by resolving the futures in engine instead of in some virtual linter.
It also seems like a better place to do it.
It should also fix caching problems I have with them (because the virtual linters don't know about the cache at all).
Test Plan: None yet.

Summary:
Fixes T2175. Git generates patches which have "\n" line endings on every system. We currently generate patches with system-dependent line endings.
Git accepts system-dependent line endings in almost call cases, but part of the parser tests for "\n" explicitly. T2175 has an example of this.
Test Plan:
Ran `arc export --git --revision D4366 > export.git` on a Windows machine, verified "\n" line endings. Ran the same with `--unified`, verified "\r\n" line endings.
(I didn't add any unit tests for this because it's Windows-dependent and very difficult to test meaningfully right now -- i.e., test that appliable patches are generated -- since the git reconstitution test doesn't run on Windows either, because we can't yet untar things there.)

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.

- mybranch having a child branch with several commits
- mybranch having two child branches
- mybranch having a child branch which has two more child branches

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.
