Fix an issue with pulling Subversion blame data

Summary:
Fixes T4067. The way `DiffusionCommitQuery` works prevents it from loading SVN identifiers in some cases without additional constraints, since "12345" might be an SVN revision 12345, or it might be the first 5 characters of a Git commit hash.

Introduce `withRepository()` as a shorthand for `withDefaultRepository()` + `withRepositoryIDs()`. This tells the query to:

  - Only look in the given repository; and
  - use the more liberal identifier resolution rules while doing so.

The practical impact this has is that blame tooltips in SVN work again. The other queries which are fixed here were never run in SVN (which doesn't have first-class branches or tags); I've cleaned them up only for completeness.

Test Plan:
  - Viewed blame in SVN, saw information again instead of empty tooltip.
  - Viewed brnaches/tags in Mercurial and Git.

Fix weird issue where INF is not respected in PHP 5.5

Summary:
After upgrading to PHP 5.5, the conduit list was not fully visible because
INF was being treated as "0" for some reason. Fixed by making it a PHP_MAX_INT

Update configuration instructions for Apache 2.4

Fixes T4061. Following the instructions in the documentation with Apache 2.4 (which is installed
with Ubuntu 13.10 and other distributions) will result in a "403 forbidden" error.

The instruction provides information on how to fix it.

Test Plan: Tested on apache 2.4 install

Tighten a regular expression in `repository.create`

Summary:
See <https://github.com/facebook/phabricator/issues/433>. We were missing a "^" here.

This should be moved over to transactions soon and then we can get rid of the duplication. :/

Test Plan: Tried to create a repository with callsign "9X", got a helpful error about "ALL UPPERCASE LETTERS".

Add support for landing to hosted Mercurial repos.

Summary: I've kept this as close as possible to the Git version for ease of review and later refactoring of them both together. At minimum, the functions to get the working dir should probably be cleaned up one day.

Test Plan: Landed a revision.

Naunce - capalities for Source object

Summary: another little piece here that basically just adds some permissions to source editing. serving it up before I do anything too complicated to make sure it seems kosher. in terms of what comes next this form needs to be dynamic based on source type so there'll be some fun there. That said, I plan to implement a more simple "phabricator form" only version to start here and flesh out a few other things like queues with that.

Test Plan: set permission to no one for source edit and got a nice error page.
