Since it may rely on the enumerated device list that could be updated
asynchronously.

d70912c034 Remove the QSA backend 
It's been broken for who knows how long, and could really do with a rewrite for
the new interface anyway.

a27096dd63 Dynamically allocate voice channel data 
Rather than allocating for a full 8 channels for each voice, when the vast
majority will only need 1 or 2. The voice channel data is relatively big since
it needs to hold HRTF coefficients and history, and this will allow increasing
the maximum number of buffer channels without an obscene memory increase.

bf50f227b9 Use a busy-wait when synchronizing against the mixer 
The mixer should have higher priority than any thread that can make AL calls,
so even on single-core systems, it shouldn't stall the mix. It will, however,
return back to the caller as soon as it can, while yielding will give up the
timeslice if there's any other thread waiting to process even if the mix is
almost done.

78251fd7e6 Fix voices being forced to update without valid properties 
When starting a voice, the source ID was set before its first update struct was
provided, creating a small window where a listener or effect slot update could
force a voice to update without it having any valid properties to update with.
Supplying the update struct first would create a different race, where the
mixer could see a voice without a source but with an update struct, causing the
update struct to be 'freed' without being applied.

The fix here is to provide the update struct before setting the source ID, and
change the mixer to ignore update structs for voices without a source ID. This
can pseudo-orphan the updates that get set on a voice just as it stops, leaving
the struct unusable until the voice is used again, or the voice gets deleted
which will clear it. But it allows the update struct to stay in place and get
applied once the voice gets a source ID.
