Summary:
We want to use it for `yield` and `invariant_violation()` which throws.
Having node instead of token would be better but this would be enough.

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:
See D2049, D2050. Identify reuses of locals as iterator variables. Before raising an error, we require:
- Variable is declared before the loop.
- Variable is used after the loop, ignoring uses as an iterator variable.
I think this identifies all problems with a very low false positive rate (the false positives are suspicious/unconventional code, but not necessarily errors).
Also fix an issue identified by the linter.
Test Plan:
- Verified this identified the bugs in D2049 and D2050.
- Ran linter against libphutil/, arcanist/ and phabricator/ (see D2051, this, and next diff).
- Ran unit tests.

Summary:
See T795. I think ~all classes in the classtree should be "abstract" or "final",
but I provided "@concrete-extensible" if you really have "Rectangle extends
Square extends Shape" or something.
I'm not totally sure this should be enabled globally by default, maybe I should
default it to DISABLED and then enable it for libphutil/arcanist/Phabricator? It
feels like it might be a little overbearing to push on everyone by defualt.

Summary:
XHPAST encounters a parse-depth problem on some files because PHP
5.2 has an un-overridable parse depth limit for JSON. The text of this error
says it is a "warning" but we currently raise an error. Make it a warning
instead.
The JSON depth is 20 until PHP 5.2.3, where it becomes 128. After PHP 5.3
it defaults to 512 and is user-configurable, which will allow us to resolve
this issue in nearly all cases.
Since I made if/else express as a list in the AST, this only actually arises
in long binary chains, most commonly string concatenation, like:
$out = 'a'.'a'.'a'.'a'...
...where each string is a variable or HTML tag and the program is constructing
a complicated document.
At some point I'll add some PHP 5.3 massaging to the XHPAST decoder itself to
raise this limit to something more huge.
Test Plan:
Ran "arc lint --lintall" on a file with a very deep binary
expression tree ("1 + 1 + 1 ...") and received a warning instead of an error.
