Summary: See T1635. I'm going to make an effort to rewrite this in a way that's safe in 32-bit PHP, i.e. without bcmath. Add test coverage to limit the chance I screw it up.
Test Plan: Ran unit tests.

Summary: This diff format is used by de-facto mercurial GUI called "TortoiseHG".
It is available as the only way to copy diff into clipboard (right click commit,
select "export", select "copy patch". I added this format support into arcanist
so revisions in Differential can be created from TortoiseHG via simple copy-
paste. Unit test added, manually tested.

Summary: When you run `hg diff -r x:y`, we get two "-r" arguments in the diff header. Currently, we parse this incorrectly.
Test Plan: Added unit test which previously failed; test now passes.

Summary:
New optional mode. If you set 'base' in local, project or global config or pass '--base' to 'arc diff' or 'arc which', it switches to DSL mode.
In DSL mode, lists of rules from args, local, project and global config are resolved, in that order. Rules can manipulate the rule machine or resolve into actual commits. Provides support for some 'arc' rules (mostly machine manipulation) and 'git' rules (symbolic ref and merge-base).
Test Plan:
Ran unit tests. Also:
```$ arc which --show-base --base 'arc:prompt'
Against which commit? HEAD
HEAD
$ arc which --show-base --base 'git:HEAD'
HEAD
$ arc which --show-base --base 'git:fake'
Usage Exception: None of the rules in your 'base' configuration matched a valid commit. Adjust rules or specify which commit you want to use explicitly.
$ arc which --show-base --base 'git:origin/master'
origin/master
$ arc which --show-base --base 'git:upstream'
Usage Exception: None of the rules in your 'base' configuration matched a valid commit. Adjust rules or specify which commit you want to use explicitly.
$ arc which --show-base --base 'literal:derp'
derp
$ arc which --show-base --base 'arc:halt'
Usage Exception: None of the rules in your 'base' configuration matched a valid commit. Adjust rules or specify which commit you want to use explicitly.
$ arc set-config --local base git:origin/master
Set key 'base' = 'git:origin/master' in local config.
$ arc which --show-base
origin/master
$ arc which --show-base --base 'git:HEAD^'
HEAD^
$ arc which --show-base --base 'arc:yield, git:HEAD^'
origin/master
$ arc which --show-base --base 'arc:global, git:HEAD^'
HEAD^
$ arc which --show-base --base 'arc:global, git:merge-base(origin/master)'
