If threads A and B queue operations simultaneously, it would
previously be possible for B's operation to complete and wake thread A
from cond_wait, which would fail its condition check and then deadlock
as only thread B is awoken when A's operation completes.
This change wakes all threads waiting on the cond var, and each thread
already checks its condition before choosing to continue.

When there is no PA server running, some older PulseAudio versions
have pa_mainloop_iterate fail instead of setting the connection state
to failed. So, we should also check the connection state after exiting
the loop to ensure it really succeeded before continuing.

PulseAudio doesn't make any buffer size guarantees. With some hardware
and some configurations, PulseAudio will fail to allocate the full
buffer requested by the application. So, we have to store the data
within winepulse until there is enough room in the PulseAudio buffer
to accept it.

winepulse depends on PulseAudio to allocate the entire requested
buffer size. If it allocates less than that size, then mmdevapi
clients may not be able to write as much data as they expect. So, we
should warn the user that the PA buffer is too small.
This is a common symptom of users setting the PULSE_LATENCY_MSEC
environment variable, which would help in some situations with
winealsa, but is no longer required with winepulse.

PulseAudio doesn't support MIDI, so we forward to ALSA to provide MIDI
support for winepulse users.
