Converting every single file at the same time in one commit is
guaranting backporting conflict hell.

eg if I'm backporting a patch from src/qemu, it is much
saner if I can cherry-pick the "Ptr" conversion from src/qemu
and only deal with conflicts in that, not the entire soure
tree.

So if we're going to do this conversion, IMHO the actual commits
need to be way more granular. At the very least I think this
needs to be split per driver, with tests/ associated with their
driver. The util/ directory needs to be split up and likewise
the conf/ directory per object type I think.

Also dropping usage of the "Ptr" should be separate from dropping
the typedefs themselves as I think that'll make conflicts easier
to deal with.
