Summary: Fixes T2112. These are fairly common now, and are used as the storage format for `hg export` and mq in most installs.
Test Plan: Ran unit tests, used `arc patch --patch`, uploaded some diffs manually.

Summary: Ref T2296. This error is unreachable right now -- when I fixed all the "\r\n" stuff, we always end up with a nonempty first line for an empty input. Do this test earlier and more explicitly. This results in a less useful error: "expected (some junk) on line 1" instead of "can't parse an empty diff".
Test Plan: Tried to parse an empty diff, got a "you can't parse an empty diff" error.

Summary: See D3963. Instead, parse these diffs so they'll work with `--raw`, etc.
Test Plan:
Generated a failing diff, added it as a test case. Fixed issue. Ran test suite. Ran `arc` against it:
$ git -c diff.suppress-blank-empty=true diff HEAD | arc diff --raw --only --conduit-uri=http://local.aphront.com:8080/
Reading diff from stdin...
Created a new Differential diff:

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:

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:
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.

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:
- I caused $parser to be reused in D3732 which I belived was safe, but actually isn't. We end up writing to the same changes. We should make it safe but there's some mess in Phabricator that needs to be cleaned up first.
- One minor error code thing, variable is undefined.
Test Plan: Ran `arc export --git` on a moved file, got a better result. Ran some command which made me hit the other case and didn't get a fatal anymore.

Summary: See T1675 for discussion. We currently strip `[abicwo12]/` from Git patches, but the user can provide arbitrary prefixes with `--src-prefix` and `--dst-prefix`, or strip prefixes entirely with `--no-prefix`. In these cases, trust they know what they're doing rather than rejecting the diff.
Test Plan: Added a bunch of tests. We have existing tests for `diff.mnemonicprefix` and normal prefixes.

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

paste. Unit test added, manually tested.
