Device enumeration now happens at startup and then is managed exclusively through hotplugging instead of full redetection. The device name list now has a unique "handle" associated with each item and SDL will pass this to the backend so they don't have to figure out how a human readable name maps to real hardware for a second time. Other cleanups, fixes, improvements, plus all the audio backends updated to the new interface...largely untested at this point, though.
