This adds two missing features to our QEMU threading and locking abstractions, qemu_thread_join and qemu_cond_timedwait, and then converts compat AIO, compatfd, and several audio subsystems. This not only saves a few lines of code, it also allows to apply certain thread and lock parameters centrally which is specifically important when using SCHED_FIFO.
Note that patch 6 is untested. Am I right that the other threads coreaudioVoiceOut::mutex addresses are created by the coreaudio core? Just curious. Furthermore note that the changes to posix-aio-compat.c depend on patches in Kevin's latest pull request.
