Summary:
Previously, running arc lint on a set of changes that only
existed in your working copy threw an exception in mercurial repos.
It was trying to use the revset "...." (i.e. the range from . to .),
which didn't parse. Even if I fix that it still doesn't work because
getRawDiffText did not include the working copy changes (which it does
in git). I removed the check so the function now acts the same as in
git and arc lint works on working copy changes. I've seen this error before
in other places so hopefully this change will also fix any other areas,
that depended on getRawDiffText working the same as git.
The logic I removed was added in D1954 to support diffing against
uncommited changes. That workflow should be unchanged. arc diff will
still prompt the user if there are uncommited changes, and the user can
still choose to abort or continue.
Let me know if I missed something important which makes this a bad idea.
Test Plan:
Edited a file in the working directory of a hg repo.
arc lint
Verified lint ran successfully.
Also ran arc diff and land with and without working copy changes to make sure
they still work. I'd kill for some tests in this area...

Summary:
Add linting capability for detecting files which contain
syntax introduced by unresolved merge conflicts. The detection is
file-type-agnostic (the only requirement is that the file is a text
file).
Test Plan:
Tested in three ways.
The first way is to add all three forms of syntax to a file to
indicate a merge conflict. HPHP will pick this up as a syntax error
before this linter reaches it.
The second way is to add the syntax in a comment. In that case, this
linter will show three warnings. For example:
$ arc lint ArcanistMergeConflictLinter.php
>>> Lint for arcanist/src/lint/linter/ArcanistMergeConflictLinter.php:
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
20
21 foreach ($lines as $lineno => $line) {
22 /*
>>> 23 >>>>>>>
24
25 =======
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
22 /*
23 >>>>>>>
24
>>> 25 =======
26
27 <<<<<<<
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
24
25 =======
26
>>> 27 <<<<<<<
28
29 */
The last test was to test on various different file types, including
JavaScript, PHP, an animated GIF, a PNG, and a Bash file to make sure
the file type detection worked. Each of the aforementioned tests
passed.

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.

- 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.
