Release 2016.8

First, there's some ongoing work in this release to support
systems without an initramfs, which is common in the classical embedded
space.  Thanks to William Manley and Gatis Paeglis!  I expect in the
future to do more work on improving ostree for the embedded case, such
as making more dependencies optional, and notably supporting libcurl.

In working on OCI/OSTree integration, we realized that some
APIs like checkout and archive import weren't introspectable.  There's
a new checkout API that use booleans rather than bitfields, and the
previous one is deprected.

Thanks to Simon McVittie for improving the test suite, and extending
it to Debian on Travis.

This release is also notable for the completion of the port to "libglnx",
so OSTree no longer depends on libgsystem.

Besides that, this release is mostly bugfixes.

Thanks to all contributors!
