ostree 2013.6

[Colin Walters <walters verbum org>]

OSTree v2013.6 is out:

https://git.gnome.org/browse/ostree/tag/?id=v2013.6

This is a quick followup release mainly to drop our GLib dependency back
down to 2.34, as it has been for a while; I accidentally introduced use
of 2.36 symbols.

I'm a bit tempted to drop the GLib dependency down even farther to 2.32
since that's what's in Debian Wheezy, if someone actually wants that, do
let me know.

Besides that, notable changes:

* Thanks to Javier for U-boot support!

* A fix for the "too many open files" bug that some people were hitting:
https://bugzilla.gnome.org/show_bug.cgi?id=706380

* I wrote a fair bit more gtk-doc, which is now online at
  https://people.gnome.org/~walters/ostree/doc/
  This replaces most of the technical content of the wiki:
