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.

- As I recall, the intent of "generateFile" was that these warnings would replace all the other warnings for that file, under the theory that if one warning caused regeneration of
the file the other warnings were irrelevant.
- However, this code never had any effect and I haven't seen any issues with the behavior.
- So, just remove it.

Summary:
In Mercurial, we figure out if the working copy is dirty with "hg diff", and do a somewhat expensive merge-base / outgoing operation if the relative commit isn't set. We can set the relative commit earlier and avoid some extra work.
We also may incorrectly cache this state (diff from merge-base of outgoing to tip) and pass the wrong rev and file dirty list to the linters.
Test Plan: Made commits which changed (A, B) and then (A). Ran "arc diff tip^". Before this change, observed full outgoing + merge base resolve and both "A" and "B" passed to lint. Observed execution of fewer commands and lint executing against "A" only after this change.

In cases where a codebase is not UTF-8, we will attempt an conversion,
if an alternative encoding is given/configured.
This is now possible in two ways:
- by configuring one under repository tracking in diffusion
- by passing an --encoding option to the workflow
If the first is not available we will make a conduit call
to do an extra check and see if an encoding is configured directly with
phabricator.
Test Plan:

it in, via stdin, or downloaded a known problematic revision from
phabricator, and they applied where they otherwise failed.

Summary:
- When you try to "arc patch" a change which adds or removes a trailing newline or alters a file with a trailing newline near the newline, the patch fails because we fail to reconstuct the "\ No newline at end of file" line.
- We don't currently record enough information about these diffs to reconstruct them with a sensible amount of effort. Store the "\ No newline at end of file" line instead of just a flag.
- There are some special rules for these lines; implement them.
NOTE: This causes some display glitching in Differential, but nothing major; I'll fix that in a followup patch.
Test Plan:
- Created a diff which added a trailing newline, removed a trailing newline, and altered a file without a trailing newline near the end of the file.
- Verified that the git version of this patch and the 'arc export --git' version of this patch are (essentially) identical.
- Verified that "arc diff" + "arc patch" can apply these changes.
