1fb9311d82 Lock the device before calling aluHandleDisconnect 
PulseAudio causes an assert if being relocked inside a callback on the worker
thread, where aluHandleDisconnect is called. We can assume it's already locked
there, so just make sure the device is locked before being calling it.

209d09ae13 Avoid locking PulseAudio's mainloop when starting and stopping capture 
The mainloop is already locked by the caller, and double-locking interferes
with the subsequent wait.

92dde81296 Add rudimentary latency tracking for mmdevapi 
This won't be as granular as it could be, since it only updates when the wakeup
event trips (which may or may not happen more often than OpenAL's mix updates).
A more correct method would be to query GetCurrentPadding directly, but that
would require sending a message to the processing thread and waiting for a
reply, since we can't guarantee COM on the calling thread.

0865db564f Move the device lock into the backend function table 
For backend-specific implementations: this should hold the audio mixer loop for
playback devices, and provide recursive mutex behavior.

ac4fc4026c Add a device method to retrieve the active latency 
This is effectively the time until the next update will be heard by the user,
or the closest approximation thereof, in nanoseconds.

f42f655ea9 Don't unlock the pulseaudio mainloop when mixing 
Lock contention could cause a lengthy delay between mixing and writing the
audio. There shouldn't be any risk of dead-locking as the device lock should
never be held when the mainloop gets locked.

785f52aa29 Only try float32 with DSound when specifically requested 
Some hardware drivers seem to have a bug where a buffer descriptor with a
32-bit float sample type ends up creating a non-float32 buffer.

051195a991 Avoid failing if ALSA can't set a buffer or period time near to our request 
These functions should not fail, but there seem to be bugs that cause them to
sometimes. We're flexible enough to handle almost anything it throws back at us
though, so anything is better than nothing here.

90ca6675c2 Allow PulseAudio to spawn a server by default 
Since only one backend is used at a time now, the issues with device ownership
aren't really prevelant anymore. An application that tries to open all
enumerated devices won't run into the problem of spawning a server and end up
preventing other backend devices from working.

0db9730a50 Add an option to allow PulseAudio to move streams 
This could be made the default, if there's a safe way to update the AL device
specifier.

92827cc467 Clamp the ALSA buffer time between min and max if setting near fails 
It seems there's some bugs with snd_pcm_hw_params_set_buffer_time_near that
cause it to return "invalid argument" despite a valid nearby buffer time being
available. Clamping the buffer time seems to mitigate the issue a bit.
