Summary:
Fixes T4349. Two issues:
- As discussed in T4349, we would trim the entire output and then require spaces when matching. This choked incorrectly if the last line of a file contained only whitespace. Use `phutil_split_lines()` instead, and regexp things more reasonably.
- We were capturing the line text, not the commit, as "revision". This isn't actually used elsewhere, but was obviously wrong. Make this consistent with Git/SVN.
Test Plan: Rigged a call up and saw reasonable output after the patch, on a working copy which threw before the patch.

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.

Summary:
Fixes T1277. The rules we use to figure out the root of the working copy get a bunch of edge cases wrong right now. A particularly troublesome one is when a user has a `/.arcconfig` or `/home/.arcconfig` or similar, which raises a completely useless and confusing error message (T1277).
Rewrite these rules to get all the edge cases correct and do reasonable things in the presence of stray `.arcconfig`. There are a bunch of comments, but basically the algorithm is:
- From the top, go down one directory at a time until we find ".svn", ".git", or ".hg".
- In Subversion, keep going down looking for ".arcconfig". In Git and Mercurial, look for ".arcconfig" only in the same directory.
- Now that we've figured out the VCS root (where the ".vcs" directory is) and the project root (where the ".arcconfig" file is, if it exists), build an identity.
This logic was also spread across three different places. Consolidate it into one and add some logging so we can figure out what's going wrong if users run into trouble.
Test Plan:
- Ran VCS (`arc list`) and non-VCS (`arc help`) commands in Git, Mercurial, and Subversions roots and subdirectories. Also ran them in non-VCS directories. Ran them with and without .arcconfig. All the outputs seemed completely reasonable.

...I want (1), but `emailuser` means (2). Instead, extract (1) with `getDisplayName()` and (3) with `getAddress()` using PhutilEmailAddress.
The implementation in Mercurial is not particularly sophisticated or magical (it just looks for "@" and "<") so we aren't really missing anything by doing this ourselves, at least today.

Summary:
Previously, arc patch would create a new commit under the existing
current bookmark in mercurial. There have been two discussions about what the
right behavior should be (D3334 and D3658). One side wants no commit at all,
and one side wants a commit under a new bookmark. The current implementation is
the worst of both worlds :(
This change makes it create a new bookmark at the revision's base before commiting,
same as the --bookmark flag used to do (which is now obsolete). That way the
existing bookmark doesn't move (in mercurial >=1.8). This is the same behavior
git has, which is convienent for groups migrating between the two.
Also makes hg's getCanonicalRevision handle svn revisions just like git. This way
arc patch will try to apply the patch to the appropriate revision in the history.
Test Plan:
Ran:
arc patch - Verified it created a new bookmark and commited on top of the
revision's base commit.
arc patch --nobranch - Verified it put the new commit on top of the current
bookmark without a new bookmark.
arc patch --nocommit - Verified it left all the changes in the working copy.

getRawDiffText did not include the working copy changes (which it does

The logic I removed was added in D1954 to support diffing against

two: the one prior to finding the revision (only applies if the user specified
--branch), and the one at the end to leave the user in a good state.
Also got rid of a 'hg outgoing' call when phases are supported. Also changed
the hg-subversion detection to just look for .hg/svn instead of running 'hg
svn info', which was taking 4 seconds.
Now arc land takes about 50 seconds. Still much worse than git's 25 seconds.

Fix this by returning nodes for these rules instead of revsets. The "arc:this" rule is automatically used in some operations, like "arc amend", so users can hit this during normal workflows, not just with weird `--base` rules.

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.

Summary:
Record author email information in `arc diff`, so we can recreate it in `arc patch` and elsewhere without creating any kind of email exposure issues.
In Mercurial, we currently store the whole string ("username <email@domain.com>"). Make this consistent with Git.
Test Plan: Created git and hg diffs, saw authorEmail populated.

Summary:
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.
Test Plan: Changed `git` to `girt`, ran `arc list`, saw a reasonable exception. Changed back to `git`, saw git detected.
