Summary:
Mercurial 'arc land --hold' was taking 90+ seconds on our large
repository. Since most of arc land doesn't require any particular working
directory, I've changed the mercurial logic to avoid all updates except for
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.
One big hot spot is in the two 'hg rebase' calls, which account for 25 seconds
(versus 11 seconds of git).
Test Plan:
Tested arc land with mercurial and git. Tested with and without the --branch
options.

Summary: This chunk of code is kind of iffy and not really correct, but make it not fail, at least.
Test Plan:
- Added a file named `swamp@2x.jpg` to a working copy.
- Used `svn propedit svn:mime-type swamp@2x.jpg@` to incorrectly set its mime type to `text/plain`.
- Ran `arc diff`.
- Saw `arc diff` "correctly" change its mime-type to a binary mime type. This isn't really correct, but doing it successfully is better than throwing an exception.

Summary:
After D4383, we escape the base commit when constructing a command like this:
hg log --rev (base::. - base)
However, if the base commit is a revset like ".^", we now escape it and Mercurial looks for a commit named ".^" (a valid mercurial branch name) instead.
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.
Test Plan: Ran "arc amend" in a Mercurial repository, didn't fatal out.

RELATIVE COMMIT
If you run 'arc diff', changes between the commit:
acf7600e6e Temporarily restore apache/license linters
...and the current working copy state will be sent to Differential, because
it is the merge-base of the upstream of the current branch and HEAD, and
matched the rule 'arc:upstream' in your args 'base' configuration.
You can see the exact changes that will be sent by running this command:
$ git diff acf7600e6e728395..HEAD
These commits will be included in the diff:
3580555e4b30598f WIP
MATCHING REVISIONS
These Differential revisions match the changes in this working copy:
(No revisions match.)
Since there are no revisions in Differential which match this working copy, a
new revision will be created if you run 'arc diff'.

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:
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.
