Subject: [PATCH 1/4] alsa: get rid of a number of assert()s
Instead of hitting an assert when any of the plugin functions is called
in an invalid context we should return a clean error to make sure
programs are not unnecessarily aborted.
This should fix issues such as http://pulseaudio.org/ticket/595

Subject: [PATCH 2/4] pulse: use PA_CONTEXT_IS_GOOD where applicable
PA_CONTEXT_IS_GOOD is a safer way to check whether a context is still
valid.
This patch also bumps the version requirement of libpulse to 0.9.11.

Subject: [PATCH 4/4] pulse: call pa_threaded_mainloop_wait() to handle spurious wakeups
pa_threaded_mainloop_wait() can wake up for no reason, according to the
specs of the underlying POSIX ptrhead_cond_wait() docs, so we need to
call it in a loop here which should be cleaner anyway.
