ostree 2012.7

[Colin Walters <walters verbum org>]

The major changes here are:

1) There's now a separate gnome-ostree module that is equivalent to the
   jhbuild modulesets: http://git.gnome.org/browse/gnome-ostree
2) ostbuild is massively rewritten; the generated contents.json is now
   *much* closer to the source manifest.  When you want to rebuild just
   a few parts after getting a binary tree, the build system now
   doesn't have to do a significant reverse engineering effort.
3) Various speedups in the core VCS
