Introduce "bin/repository" for repository management

Summary:
Nothing new or exciting here yet, just moving the random scripts/repositories/ things to bin/repository. Also add `repository list`.

(Console stuff comes from D2841.)

Test Plan: Ran `repository list`, `repository pull`, `repository discover`, `repository discover --verbose`, `repository help`.

Add a --repair flag to "bin/repository discover"

Summary:
If a repository is missing commits because they mysteriously vanished, there's no reasonable way to get them back right now. Provide a way to ignore the state in the database and rediscover the entire repository unconditionally.

We don't queue any reparses or anything, but when I move reparse into this script we can hook things up or something. This generally shouldn't be too important anyway.

Test Plan: Ran `repository discover --repair` on Phabricator.

Use subprocess output streaming to improve performance of Git commit discovery

Summary:
Improve performance of large discovery tasks in Git by using subprocess streaming, like we do for Mercurial.

Basically, we save the cost of running many `git log` commands by running one big `git log` command but only parsing as much of it as we need to. This is pretty complicated, but we more or less need it for mercurial (which has ~100ms of 'hg' overhead instead of ~5ms of 'git' overhead) so we're already committed to most of the complexity costs. The git implementation is much simpler than the hg implementation because we don't need to handle all the weird parent rules (git gives us to them easily).

Test Plan:
Before, `discover --repair` on Phabricator took 35s:

  real	0m35.324s
  user	0m13.364s
  sys	0m21.088s

Now 7s:

  real	0m7.236s
  user	0m2.436s
  sys	0m3.444s

Note that most of the time is spent inserting rows after discover, the actual speedup of the git discovery part is much larger (subjectively, it runs in less than a second now, from ~28 seconds before).

Also ran discover/pull on single new commits in normal cases to verify that nothing broke in the common case.

Remove leading "/" so that "git cat-file" works

Summary:
When the absolute path is used for load file (loadFileContent(()), it fails in git. For example:

  /var/repo/page_admin_app
  > git cat-file blob '4d6c03923006d6c444660f2c734fe03e10fd20bd':'/ios/PageAdminApp/Resources/splash/De           fault-Portrait@2x~ipad.png'
  fatal: Not a valid object name 4d6c03923006d6c444660f2c734fe03e10fd20bd:/ios/PageAdminApp/Resources/s           plash/Default-Portrait@2x~ipad.png

This is breaking the auto-closing for about 8 revisions like

https://phabricator.fb.com/rPPA4d6c03923006d6c444660f2c734fe03e10fd20bd ...
https://phabricatorcator.fb.com/rPPA51acb7e482aab0c491b530ed19dddc741d50f673 ...

Test Plan:
- reparsed https://phabricator.fb.com/rPPA4d6c03923006d6c444660f2c734fe03e10fd20bd successfully with corresponding differential revision being closed.

- verified that without leading '/', loadFileContent for svn still works. Both of the following commands worked (note the double '/' right before 'tfb':

  svn cat svn+ssh://svn.vip.facebook.com/svnroot//tfb/trunk/www/flib/intern/cachearchiver/regenerators/wurfl/CacheArchiveWurflRegenerator.php@579700

Prevent Firebug from crashing in Firefox 13 / Window 7

Summary:
Simpler fix for D2572. Not entirely sure why Firebug is crashing Firefox. It appears to be callstack depth related, possibly? You can sort of reproduce this like this:

  >>> var f = function(n) { n && f(n - 1); }
  >>> f(10000); // Takes a few ms to run.
  >>> f(40000); // Takes a few ms to run.
  >>> f(50000); // Hangs Firefox.

If there are 2,000 files, we currently hit a stack depth of around 4,000 with the pass() rules, so it seems like we should be 10x short of exploding.

Anyway, this keeps us from increasing stack depth for menus that aren't currently open and stops Firebug from crashing.

Test Plan: Clicked 2000-diff revision in Firefox.
