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.

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.

Instead of searching from the beginning of the voice list for each source, just
continue searching from the last source's voice.

a8162a77c2 Use an array of ALvoice pointers for the active voices 
This allows growing the array atomically with the mixer since the ALvoice
objects themselves don't move, and a new larger array of them can be swapped in
without blocking the mixer.

04e5b23286 Don't bother looping the calculated source offset 
The offset shouldn't be in a non-wrapped state when playing, and when not
playing it's always 0 anyway.

8665f404a5 Always start streaming sources from the start of the queue 
For sources that don't start with an offset, at least. This is necessary so the
completed buffer event will give the correct count if it starts with null or
empty buffers that become processed.
