c8efb41811 Fix hg arc land on hg-svn repos
Summary:
arc land on a hg-svn repository would fail because arc land
uses 'hg push -r' to specify which revs to push which is not supported
by hg-svn. Now we just use 'hg push' which, when used against svn, only
pushes the current branch (which happens to be the branch we're trying to land).

We can't use standard 'hg push' for non-svn repos though because when used
against a vanilla hg repo 'hg push' pushes all branches.

Also remove --new-branch from 'hg push' because it's extremely
unlikely that a person wants to create a new branch on the server via
arc land.

Test Plan:
Ran arc land on a normal hg repo, verified it used 'hg push -r'.
Ran arc land on a hg-svn repo, verified it used 'hg push' and it pushed the
correct changes.

a1b902b190 Cache results of repository linters
Summary:
The cache key is repository base revision and hash of all modified files.
It isn't perfect in SVN where every file might have a different revision.
It's also suboptimal as just committing or amending changes the cache key even if the files contents weren't modified.
We can improve it later, perhaps by using previous revision and files modified since it.

Test Plan:
Changed granularity of XHPAST linter to repository.
Linted the same repo twice, verified that it was read from cache the second file.
Changed a single file, verified that all files were re-linted.

880964af83 Allow hg arc land when no rebase is necessary
Summary:
Previously, trying to arc land in a mercurial repo would
fail if the local branch was already at the tip of the onto branch
(since hg rebase exited with code 1).  This change makes it check
if a rebase is needed before executing the rebase.

Test Plan:
hg init foo
cd foo
hg bookmark master
touch a && hg add a && hg commit -ma
// setup your .arcconfig
cd ..
hg clone foo foo2
cd foo2
hg bookmark mybook
touch b && hg add b && hg commit -mb
arc land --onto master --revision <your rev number>

Arc land should succeed.  I also tried landing when a rebase was
necessary and it still worked.

40102252bf Fix arc diff when run from a git submodule
Summary:
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.

Test Plan: submit a diff from a submodule

38e2e1336f Generate Git patches with "\n" metadata line endings unconditionally
Summary:
Fixes T2175. Git generates patches which have "\n" line endings on every system. We currently generate patches with system-dependent line endings.

Git accepts system-dependent line endings in almost call cases, but part of the parser tests for "\n" explicitly. T2175 has an example of this.

Test Plan:
Ran `arc export --git --revision D4366 > export.git` on a Windows machine, verified "\n" line endings. Ran the same with `--unified`, verified "\r\n" line endings.

(I didn't add any unit tests for this because it's Windows-dependent and very difficult to test meaningfully right now -- i.e., test that appliable patches are generated -- since the git reconstitution test doesn't run on Windows either, because we can't yet untar things there.)

59e13f666f Correct spelling for "arc" commands
Summary:
I type "arc brnach" about 300 times per day.

  - Allow arc commands to be specified by unique prefix ("exp" for "export", "lib" for "liberate").
  - Allow arc commands to be specified by unique levenshtein edit distance <= 2 ("brnach" for "branch", "halp" for "help", "ptach" for "patch").
  - Reorganize code out of "arcanist.php".

I think this will be uncontentious because arc commands are rarely destructive, but if people complain we can either require certain commands be typed exactly (maybe "land"?) or allow this feature to be disabled in configuration.

219dbe2374 Refuse writing to undeclared properties in workflows
Summary: I don't know how to not be strict here plus we (Arcanist developers) don't have access to user's error log.

Test Plan:
Undeclared `ArcanistDiffWorkflow::$console`, then:

  $ arc diff

2871d00f96 Allow checking out branches in arc branch
Summary:
The main added value is loading the branch name from revision.
Sometimes I know the revision ID but I don't know the branch name.

The missing piece is the starting point of the branch.
I was thinking about using `arc.land.onto.default` but we also need to get 'origin'.

This is also the last step of a simple workflow where underlying VCS is not abstracted away.
In future, we can implement this for other APIs.

Test Plan:
  $ arc branch new_branch
  $ arc branch new_branch
  $ arc branch D4168
