3602d2aa15 Break arc land run() into smaller functions
Summary:
Refactor the arc land code into several
functions so it's easier to maintain. This is in
preparation for adding hg support to arc land
in my next commit.

Without this refactor, adding hg support makes the run()
function too big.

Test Plan:
Set up a git repo and clone with a branch scenario.
Example: https://secure.phabricator.com/P614
Ran and verified:
arc land
arc land --keep-branch
arc land --merge
arc land --merge --keep-branch
arc land --hold
arc land --revision <another phabricator rev>

b549f565c9 Add a very basic Scala (SBT) linter.
Summary:
SBT is the most common Scala buildsystem. This adds an extremely basic and
slightly horrible linter to check SBT's output for warnings and errors.

Test Plan:
Tested this with a Scala project I've been working on for some time.
It seemed relatively sane.

db25adb069 Parse "--help" correctly in arc
Summary:
We delegate parsing to `PhutilArgumentParser` but then skip the parts of the code which do something with this flag.

In particular, `arc --help list` just runs `arc list`.

See https://github.com/facebook/arcanist/issues/58

Test Plan: Ran `arc --help`, `arc list --help`, `arc --help list`, `arc --help help --help`. Got expected help in all cases.

3cfd58c29c Allow caching lint results
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)

22d8e7467b Allow running arc diff without git commit
Summary:
There's quite some logic in here:

- It automatically decides whether to create a new commit or amend.
- It partially respects 'default-relative-commit'.
- However if it points to a closed revision then it creates a new commit.

Resolves T2025.

Test Plan:
`arc diff` on:

- Clean committed repository.
- Dirty repository without commit since 'default-relative-commit'.
- Dirty repository with non-revision commit since 'default-relative-commit'.
- Dirty repository with revision commit since 'default-relative-commit'.
- `arc diff HEAD^` on dirty repository on top of closed revision.

c8409bb5b2 Fix an issue where arc diff would loop indefinitely for a property change
Summary:
When we hit a diff which is missing file context, we try to pull it synthetically later. This works for moves and copies, but currently fails for property changes. Since it failed, we didn't have context, so we'd try to pull it again...

The general problem this creates is that when you mark a file "+x" without changing it, we can't show you the content in Differential. Not a huge deal. In some future diff, I'll build the content synthetically.

Adds commits to cover this behavior:

66d204be81 Delete license headers from files
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.

d96eaed097 Partially revert D3748
Summary:
D3748 attempted to improve the behavior of `arc diff` when dealing with files merged from another branch, but had the side effect of marking all normal edits and deletes as adds. Revert this side effect, at least. This likely degrades the merging case, but it's comparatively rare, and editing/deleting files is very common.

I'll make an effort to fix this properly (and back it with DirectoryFixture tests) when I deal with T1947.

Test Plan: Ran `arc diff --preview` for a change that edits or removes files.

519e23f3a4 In arc diff, always check that you own a revision before trying to do anything with it
Summary:
Some users assume they can update anything, not just revisions they own (see https://github.com/facebook/arcanist/issues/54).

Currently, if you `arc patch` or `arc amend` and get a commit message, then `arc diff` for a revision you don't own, we:

  - Fail early with a very confusing message ("You can not review a revision you own!") if you are on the "Reviewers" line, until D3820.
  - Or fail very very late with a good error message, but after lint, unit and update messages.

Instead, check that you own the revision as early as we can.

Test Plan: Tried to update revisions I didn't own, got good error messages early on (with D3820).

6be5cfd104 Split paths on "diff --git" lines correctly in more cases
Summary:
See T1973. In T1675, we addressed parsing of diffs with `--no-prefix` or custom `--src-prefix` and `--dst-prefix` flags. However, this inadvetently broke diffing of files with spaces in their names, which Git does not quote. They look like this normally:

  diff --git a/old file b/new file

Prior to D3744, we accidentally got this right by looking for the `a/` and `b/`. However, we no longer do, and instead produce nonsense results.

This problem is difficult because for files with spaces, `git diff --no-prefix` may generate an ambiguous line like:

  diff --git a b c d e f g

From this line, we have no way to deterine if this moves "a" to "b c d e f g", or "a b c d" to "e f g", or anything in between. In some diffs we have more information later on, but in some cases we do not, e.g. for binary diffs without `--binary`.

Try to get this right in as many cases as possible:

  - If there are quotes, we can unambiguously get it right. This only happens for filenames with quotes or unicode characters, however.
  - If there is exactly one space, we can unambiguously get it right.
  - Interpret the common case of `a/<anything> b/<anything>` in the most-likely-correct way again.
  - Interpret the rare case of `<anything> <that same thing>` in the most-likely-correct way.
  - Complain about any `a b c d e f g` garbage.

Test Plan: Ran unit tests. Created a diff of a file called "File With Spaces".
