OSTree v2016.7

[Colin Walters <walters verbum org>]

OSTree v2016.7 is now available:

https://github.com/ostreedev/ostree/releases/tag/v2016.7

This release is almost entirely bugfixes.  Most notable is a fix for a
relatively rare race condition in the pull code on cleanup (after
completion), and also a memory leak.

Besides that, there are improvements for the test suite, some more
porting away from libgsystem, a bugfix for static deltas important to
flatpak, build tweaks for older glib, etc.

Thanks to all contributors!
