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.

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).

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.

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.

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".

Summary:
We have coverage for generating patches, applying them, and making sure they reproduce the original repository state. However:
- The code uses simplified patch generation which omits some flags like `-M` and `-C`, and generally produces less rich patches than we really produce. Instead, produce patches the same way `arc diff` does.
- We don't test the intermediate change representation. In theory it's not too important because if we get it wrong the output should be wrong, but in practice it makes it easier to nail down issues. We can also generate less-rich patches which still apply correctly, but would prefer not to.
- Similarly, we don't test the intermediate patch representation. This is almost entirely redundant with simply applying the patch, but easier to visualize.
Add coverage for all that stuff and fix some bugs with `-M` / `-C` patch generation that weren't caught under the simpler patch generation.

Summary:
This is horrible and git specific, but fixes a case where people are using "arc
patch --nobranch ..." when they're not currently on a branch.
The old code assumed you were on a branch and used getBranchName() to record
this, in order to return to that branch later and cherry-pick the patch.
When not on a branch, and using arc patch --nobranch, this was trying to return
to the branch '(no branch)'.
Now, I detect that we're not on a branch and just record what HEAD is instead.
Test Plan:
Checkout the SHA of master (so I'm on master, but not on a branch) then try to
patch it with a feature diff:
