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.

Summary:
If linter with file cache granularity stops linting then we don't run it on the same path next time.
But we still run linters with non-file cache granularity causing that they run even on the paths that would be stopped otherwise.
Test Plan:
Put global granularity linter after Generated linter.
Caused an error from this linter but in ignored path.
Verified that 'stopped' is saved in `lint-cache.json`.
Linted the same files second time, verified that the path is still skipped (wasn't before).

Summary:
Some errors (duplicate declaration, invalid number of arguments) have more related places.
We need to notify user if he changes any related place.
This could be currently achieved by triggering errors instead of warnings or by including both files in the range (impossible if the locations are in different files) or by issuing multiple errors.
All options are too aggressive.
Test Plan: Issued error on unmodified line with other location on modified line.

Summary:
FB runs some linters on background and it's a magnificent hack using `ParallelLinter` (two instances), `BackgroundLinter` and `FutureLinter`.
I want to simplify this by resolving the futures in engine instead of in some virtual linter.
It also seems like a better place to do it.
It should also fix caching problems I have with them (because the virtual linters don't know about the cache at all).
Test Plan: None yet.

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.

$ 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)

Another solution would be to extend `ArcanistLinterTestCase` from `ArcanistArcanistLinterTestCase` and return null in `getLink()` to avoid code duplication but I prefer clean class hierarchy.

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.
