Fixes for hashes not having intrinsic order

[Daniel Macks]

Two bugzilla items:

https://bugs.freedesktop.org/show_bug.cgi?id=79666
https://bugs.freedesktop.org/show_bug.cgi?id=79689

involve user-visible output that is randomly ordered because pkg-config is dumping a hash-table in whatever order the GHash uses internally. Having the output sorted makes it easier to read or process...just a matter or sorting the list of keys before spewing the key/values to stdout. Each has a patch, but I'm not sure the right kind of sorting is being done. Please let me know if there's more work needed on them.
