This is needed for synchronization: motions will have to start
(with a specific start time offset) from a point in the code where
only the motion object is available.
I added/used LLMotionController& in a previous commit, this was
now changed into a pointer. There is (obviously) not much reason
for that, but also no disadvantage: the diff relative to LLs code
doesn't get larger since the references where already added, too.

For these standard motions, the viewer likes to very frequently
flood-call startMotion/stopMotion sometimes, which at the very
least needs a LLUUID lookup in a std::map. In particular, this
is done for two of them for every avatar in the sim every frame.
This code makes it possible to test if that makes sense by
merely doing a bit test.
