d45dd9c668 Remove the sinc8 resampler option 
Perf shows less than 1 percent CPU difference from the higher quality bsinc
resampler, but uses almost twice as much memory (a 128KB lookup table).

2448f88e70 Return some device latency by default 
A device will never have 0 latency. OpenAL Soft itself uses a sample buffer
length of UpdateSize*NumUpdates, and during playback will have about
(NumUpdates-1) periods filled, more or less. Without a more accurate
measurement from the playback system, this is better than reporting 0.

909193a345 Reorganize ALvoice members 
This places the Send[] array at the end of the struct, making it easier to
handle dynamically.

5a50c46c22 Make ALsourceProps' Send array dynamically sized 
ALsourceProps' Send[] array is placed at the end of the struct, and given an
indeterminate size. Extra space is allocated at the end of each struct given
the number of auxiliary sends set for the device.

0d19a20901 Make the source state atomic 
Since it's modified by the mixer when playback is ended, a plain struct member
isn't safe.

Also explicitly link with libz for alffplay, since static ffmpeg libs need it.

9f10ae466c Convert the OpenSL backend to the new backend API 
This also removes the buffer queue callback's call to aluMixData, which could
potentially block on a mutex.

Chris Robinson
3cc88b0aab Use an all-pass series on each late reverb line 
This attempts to improve the smoothness of the late reverb decay by passing
each line through multiple all-pass filters. Some work is still needed to work
better in high-density and not-so-high-diffusion environments.

This also removes the decay from the early reflections, since it's no longer
continuous feedback.

1ebfce4cac Improve the ambisonic upscaling methods 
This now takes advantage of the differences seen in generated decoder matrices
for first-order compared to second- and third-order, such that with the
appropriate frequency-dependent scaling applied to first-order content, the
result is identical with a higher-order decoder matrix compared to a first-
order matrix for the same layout.

Chris Robinson
cbb796bf31 Use ALsizei for sizes and offsets with the mixer 
Unsigned 32-bit offsets actually have some potential overhead on 64-bit targets
for pointer/array accesses due to rules on integer wrapping. No idea how much
impact it has in practice, but it's nice to be correct about it.

9f23d17333 Use second-order ambisonics for basic HRTF rendering 
This should improve positional quality for relatively low cost. Full HRTF
rendering still only uses first-order since the only use of the dry buffer
there is for first-order content (B-Format buffers, effects).
