- don't bother trying to fix compiler optimization flag tests. they're
badly broken/linux spcific, and we don't use them anyway.
- the net source client became a "real" client (executable), instead of
an "in process" client (plugin)
- previous sun_driver patches accepted upstream, plus:
* fix cycle timing in duplex mode by moving calculations and function
calls out of the poll() synchronization loop
* shorten xrun and silence writing/reading messages
* remove unused variables
* attempt to stop continuous playback underruns in duplex mode that are
caused by the capture buffer overrunning
* try harder to make sure we have pristine buffers after
sun_driver_start()
* use native endian audio encodings
* report a delay when poll() times out, instead of effectively running
a null cycle
now jack works on my r10k sgi :)
