Summary:
This guards against stability issues with the output format of 'git
blame' (such as git config, localization (ref T5554) or future changes).
For example, `git config blame.blankboundary true` breaks `arc cover`
before this patch.
Test Plan:
* Set `git config blame.blankboundary true` on a test repo.
* Ran `arc cover`. It failed with an exception ("Bad blame?").
* Applied this patch.
* `arc cover` works.

Summary:
Ref T5554. Both the current branch name (if on a branch), as well as the
list of all local branches, can be retrieved without having to parse the
output from "git branch".
Unfortunately, there seems to be no git plumbing for "get list of
branches containing this commit" yet.
(see http://marc.info/?l=git&m=141408477614635&w=2)
For that case, this commit whitelists the output from "git branch" using
the known valid branch names from "git for-each-ref".
Test Plan:
Set up a test repo with this structure:
```
| * Commit B1, on branch "subfeature"
| /
| * Commit A1, on branch "feature"
|/
* Commit M1, on branch "master"
|
```
In `subfeature`, I tried:
* `arc which --base 'git:branch-unique(master)'`
* `arc feature`
After that, I detached my HEAD (don't worry, I got better) and tried again.
Nothing looked broken.
(Tested with git 1.7.2.5 and 2.5.0.)

Ref T5554. This makes git remote URL detection locale-agnostic.
The previously suggested `git config remote.origin.url` command does
almost the same, but does not support the URL rewriting features in
git-config (`url.<base>.insteadOf`).
This one does, although it has the unintuitive behavior of just printing
the passed remote name when the remote does not exist, or even when
called outside a git repo.
Test Plan:
* Switched to non-english locale in which git has a translation.
* Ran `arc which` on the Arcanist repo. It could not determine the remote URI.
* Applied patch, `arc which` found the URI.

Summary:
Introducing `--head` caused us to run `git diff base..head` explicitly.
However, we can now hit this workflow:
- We resolve `HEAD` as commit `aaaa1`.
- This is cached.
- We notice dirty working copy changes and prompt the user to amend them to HEAD.
- The user accepts the amend.
- We amend, creating commit `bbbb2`.
- We dirty the commit range and reload the working copy. This //does not// dirty the cache of HEAD.
- We run `git diff`, but it uses the old cached HEAD: `git diff base..aaaa1`.
- This works fine (`aaaa1` still exists, it's just not on any branch) but produces the wrong diff (without amended changes).
To resolve this, implement the "dirty the cache when the range reloads" hook.
Also never try to amend if the user provides `--head`.
Test Plan:
Ran `arc diff --only --trace` in a working copy with a new commit and some uncommitted changes.
- Prior to this change, saw a `git diff base..aaaa1` command and the wrong diff.
- After this change, saw a `git diff base..bbbb2` command and the correct diff.

Summary:
Ref T4343. Continues the process of reducing the prominence of Arcanist Projects. Primarily:
- Query Phabricator to identify the working copy based on explicit configuration, or guess based on heuristics.
- Enhance `arc which` to explain the process to the user.
- The `project_id` key is no longer required in `.arcconfig`.
Minor/cleanup changes:
- Rename `project_id` to `project.name` (consistency, clarity).
- Rename `conduit_uri` to `phabricator.uri` (consistency, clairty).
- These both need documentation updates.
- Add `repository.callsign` to explicitly bind to a repository.
- Updated `.arcconfig` for the new values.
- Fix a unit test which broke a while ago when we fixed a rare definition of "unstaged".
- Make `getRepositoryUUID()` generic so we can get rid of one `instanceof`.
Test Plan:
- Ran `arc which`.
- Ran `arc diff`.
- This doesn't really change anything, so the only real risk is version compatibility breaks. This //does// introduce such a break, but the window is very narrow: if you upgrade `arc` after this commit, and try to diff against a Phabricator which was updated after yesterday (D8068) but before D8072 lands, the lookup will work so we'll add `repositoryPHID` to the `differential.creatediff` call, but it won't exist in Phabricator yet. This window is so narrow that I'm not going to try to fix it, as I'd guess there is a significant chance that no users will be affected. I don't see a clever way to fix it that doesn't involve a lot of work, either.

A git submodule looks a lot like a normal git repo, but the .git
directory is replaced with a file that git reads to find the real
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
git directory is a directory named .git at the toplevel of the tree, we
use the appropriate git command to get the correct git directory.

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.

# 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.
