Summary:
See D4049, D4096.
- Move commit range storage from Mercurial and Git APIs to the base API.
- Move caching up to the base level.
- Store symbolic name and resolved name separately, so we can re-resolve the correct commit from the symbolic name after dirtying caches.
- Rename `supportsRelativeLocalCommit()` to `supportsCommitRanges()` (old name wasn't very good, and not consistent with new terminology like the `--base` flag).
- Rename `getRelativeCommit()` and `setRelativeCommit()` to `getBaseCommit()` and `setBaseCommit()`.
- Introduce `reloadCommitRange()` and call it from `reloadWorkingCopy()`.
I think this fixes the problem in D4049, and provides a general solution for the class of problems we're running into here, with D4096. Specifically:
- We no longer get dirty caches, as long as you call reloadWorkingCopy() after changing the working copy (or call a method which calls it for you).
- We no longer get order-of-parsing-things problems, because setBaseCommit() reloads the appropriate caches.
- We no longer get nasty effects from calling `requireCleanWorkingCopy()` too early.
Test Plan: This is pretty far-reaching and hard to test. Unit tests; ran various arc commands. :/

Summary:
This allows using new methods without the need for bumping version number.
The usage is not neccessary because we already bumped the version number for this but I wanted to have a callsite.
Test Plan:
Made a typo in method name, then:
$ arc lint --only-new 1

Summary:
We can add `GRANULARITY_DIRECTORY` and `GRANULARITY_REPOSITORY` later.
Repository granularity may use current commit + changes.
Directory would need to use hashes of all files in dir which would be quite expensive.
Test Plan:
$ echo '<?php class A extends B {}' > A.php
$ arc lint --cache 1
$ arc lint --cache 1
$ echo '<?php class B {}' > B.php
$ arc lint --cache 1
$ arc lint --cache 1
$ rm B.php
$ arc lint --cache 1
$ arc lint --cache 1

Summary:
There is one big decision: How to get linters version.
I've created `getCacheVersion()` which is supposed to be bumped every time engine or any linter is changed.
This is not very nice but the other alternative (detect this automatically) seems worse:
- The engine may be outside repo and may or may not be under version control so getting its version through something like `git log` may not be even possible.
- If it is in the same repo then every rebase will obsolete the whole cache.
Even though bumping the version manually is PITA I still think it's a better solution.
Test Plan:
$ time arc lint --cache 1
# verified file
$ arc arc lint --cache 1
# added some debug output to see the cached results
# also observed better time (.57 s instead of 2.19 s)

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in unit tests and LICENSE file.

Summary:
When some linter throws then we don't print any result.
This is bad in case when the linter threw e.g. because of syntax error in some file which some other linter will tell us about.
Test Plan: Threw from a linter, made lint error in a file, saw error then exception.

Summary:
Currently, adding a new workflow requires you to override ArcanistConfiguration, which is messy. Instead, just load everything that extends ArcanistBaseWorkflow.
Remove all the rules tying workflow names to class names through arcane incantations.
This has a very small performance cost in that we need to load every Workflow class every time now, but we don't hit __init__ and such anymore and it was pretty negligible on my machine (98ms vs 104ms or something).
Test Plan: Ran "arc help", "arc which", "arc diff", etc.

HPHP now autoloads in `is_subclass_of()`.
I've left the `class_exists()` check as the code is more explicit.

}
is_subclass_of('C', 'stdClass');

Summary:
We want to have a class of lint problems which are displayed to author and attached to revision but don't require excuse in diff workflow.
Lint advices already serve this purpose but no linters emit them because they need `--advice` flag to be processed.
By always enabling advices, we can switch more linters from warnings to advices and don't stop the diff workflow for them.
This diff also bumps down default severity of TODO rule.
Test Plan: Made lint advice mistake, ran `arc lint`.

Summary:
This uses a similiar approach as with postponed unittests, allowing
the lint workflow/engine to report postponed linter names. After
the lint engine is run, a separate method is used to collect any
postponed linters and these are reposted to the diff via the
"arc:lint-postponed" property.
Also, a ##diff.wasCreated## was added allowing hooks to be called
immediately after the call ##differential.creatediff## with the
returned diff ID.
Test Plan:
Created diffs with a dummy lint engine which always reports a
postponed linter.
