Subject: [PATCH 1/4] thread: Fix preexisting uncrustify problem
uncrustify seems to want a little more indentation, so this

Subject: [PATCH 2/4] tests/dbusmock-templates/rtkit: Add
MakeThreadHighPriority
mutter will soon need to call an additional method in RTKit,
MakeThreadHighPriority.
In preparation for that, this commit stubs it out in the
dbusmock template.
