Update to latest from DRI CVS. Primary new feature is mostly-complete smpng

locking, and the apparently unnecessary locking for -stable has been removed.
This may fix issues with missed interrupts since April, which manifested
themselves as slowdowns or hangs in radeon, in particular. Many cleanups also
took place.  In the shared code, there are improvements to r128 driver
stability.
