ba78000b38 Make arc patch create a bookmark by default in hg
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.

Also verified arc patch still works with git.

2900ab6abd Added automatic stash / unstash support for Git in arc diff.
Summary:
- Added arc.autostash option to have this behaviour off by
default (but configurable on a per-project basis).
- Automatic stashing of changes now informs the user of how
to restore their working directory if Arcanist unexpectedly
terminates.
- Fixed an issue with finalizeWorkingCopy when the workflow
didn't require a clean working copy.

Test Plan:
Test `arc diff` when there are changes in the working
directory; by default it should tell you to stash or commit.
Turn on the arc.autostash option and try again; it should
automatically stash with a message on how to recover, and
it should restore the working directory automatically under
almost any circumstances (other than an unrecoverable error).

9963323b91 Make arc land for hg more robust to failures
Summary:
Adds error handling for several kinds of failure in arc land for
mercurial.  Previously it would often leave the repo in a confusing state
if something failed.

- Aborts the land if pull brings in a diverged 'onto' branch.
- Aborts the rebase if there is a conflict. This leaves the repo exactly as
it was before, so the user is not left with a half finished rebase.
- Don't delete the original non-squashed branch until the push succeeds.
- If the push fails, strip the temporary squashed commit. This leaves the
'onto' branch back on the latest commit from the server, and leaves the users
original nonsquashed branch around.
- Always leave the user back on their original branch after an error.

Test Plan:
Ran arc land:
- with pull causing a diverged 'onto' bookmark
- with the 'onto' bookmark already diverged
- with the rebase causing conflicts
- with a push that failed due to a commit hook
- with a successful land
- with a successful collapse and land

In all failure cases the repo was left exactly as it was before arc land,
except for the push-failed case, where the only change was that the branch
was correctly on top of the destination branch due to a successful rebase.

Used bookmark name "foo bar-gah" to test that crazy bookmark names still work.

Summary:
Arc patch was committing with -A (--addremove) which meant any random

Summary: Changes message for `arc land` that displays current branch or bookmark (if none is specified) to appropriately use the term 'bookmark' when on a bookmark in an hg repository.

~/test/hg-test$ hg branch

Usage Exception: Source testmark is a bookmark but destination default is not a bookmark. When landing a bookmark, the destination must also be a bookmark. Use --onto to specify a bookmark, or set arc.land.onto.default in .arcconfig.

Summary:
arc diff called 'hg cat' twice for every image binary in the diff.
This turns out to take 1 second per call on a large repo because mercurial

commands.  This makes the cost constant relative to the number of
images being uploaded.

0cb1b7efad Fix arc lint on working copy changes in mercurial repos
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...
