Fix tab indentation missing in Diffusion

This seems to be a specific of how browsers are dealing with
spaces/tabs. Multiple spaces works just fine, but multiple
tabs were treating as a single space which breaks indentation.

Now made it so tabs are replaced with 4 spaces. Not ideal but
still better than fully unreadable code. This also matches to
how differential is handling tabs.

Ref T2495. See: <https://github.com/facebook/phabricator/issues/487>

Begin making change parsers testable

Summary:
Ref T4327. There are a bunch of other probably-related tasks too, some linked there.

We have some rare/unusual bugs in the change parsers, mostly in Subversion, but it's terrifying to touch them because they're complicated and fragile and have no test coverage.

To fix this stuff, I want to make them more testable. In particular, they basically end with this big INSERT right now. Instead, I'm going to make them return objects representing the data to be inserted, then have the common infrastructure do the insert. This gives us two benefits:

  - Reduced code duplication on the insert;
  - we can stop before the insert and have unit tests examine the objects.

This swaps the Git parser over, but doesn't swap the hg/svn parsers yet. I'll do those separately, the SVN one looks a bit tricky.

Test Plan:
  - Used `scripts/repository/reparse.php` to reparse a Git commit, with `--trace`. Verified it looked the same as before and the SQL that was executed seemed reasonable.
  - Did the same for `hg` / `svn` commits, to make sure I didn't derp anything. These aren't expected to do anything differently.

Mailgun receive support

Summary:
As you've suggested, I took the SendGrid code and massaged it until it played nice with Mailgun.

btw - unless I'm missing something, it appears that the SendGrid receiver lets you spoof emails (it performs no validation on the data received).

Test Plan: Opened a task with Mailgun. Felt great.

Add more Subversion unit tests

Summary:
Ref T4327. Adds additional SVN tests to cover:

  - replacing a file with a file;
  - replacing a file with a directory;
  - removing a directory with files in it;
  - adding a directory with files;
  - copying a directory and adding and deleting files inside it.

Test Plan: Ran unit tests. One of these has a slightly irregular parse, see inline.

Improve exception reporting behavior for core exceptions

Summary:
See <https://github.com/facebook/phabricator/issues/487>. If an exception is thrown too high in the stack for the main exception handling to deal with it, we currently never report a stack trace. Instead:

  - Always report a stack trace to the error log.
  - With developer mode, also report a stack trace to the screen.

Test Plan: Added a high-level `throw` and hit both cases. Got traces in the log and traces-under-developer-mode on screen.

Do not perform write in PhabricatorDaemonLogQuery by default

Summary:
See <http://github.com/facebook/phabricator/issues/487>. By default, we perform a write in this query to moved daemons to "dead" status after a timeout. This is normally reasonable, but after D7964 we do a setup check against the daemons, which means this query is invoked very early in the stack, before we have a write guard.

Since doing this write unconditionally is unnecessarily, surprising, and overly ambitious, make the write conditional and do not attempt to perform it from the setup check.

(We could also move this to a GC/cron sort of thing eventually, maybe -- it's a bit awkward here, but we don't have other infrastructure which is a great fit right now.)

Test Plan: Hit setup issues and daemon pages. Will confirm with user that this fixes things.
