TODO:
- directsound: incomplete and somewhat broken
- osx: understand why AudioQueueGetCurrentTime can return negative mSampleTime
- test (and fix) sub-prefill size data playback
- report stream delay instead of position; leave position calculation to user
- capture support
- capture and output enumeration and configuration
- also expose default hardware config to allow decisions on speaker layout
- prefill occurs at different times in each backend:
- pulse prefills async off worker thread after init
- coreaudio prefills during init
- alsa prefills async after start
- expose configured prefill size; may differ from requested latency
- solved by exposing stream delay
- xruns may occur in user callback but also in audio hardware
may need to expose details of hardware xruns to user api
- document thread safety
- document which calls may block, and when effects take effect
- document what's permissible inside callbacks
- implement basic channel mapping for surround
- vorbis has documented mapping based on channel count (if mapping type ==
0) -- http://xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-800004.3.9

/*
Microsoft wave audio docs say "samples are the preferred time format in which
to represent the current position", but relying on this causes problems on
Windows XP, the only OS cubeb_winmm is used on.
While the wdmaud.sys driver internally tracks a 64-bit position and ensures no
backward movement, the WinMM API limits the position returned from
waveOutGetPosition() to a 32-bit DWORD (this applies equally to XP x64). The
higher 32 bits are chopped off, and to an API consumer the position can appear
to move backward.
In theory, even a 32-bit TIME_SAMPLES position should provide plenty of
playback time for typical use cases before this pseudo wrap-around, e.g:
(2^32 - 1)/48000 = ~24:51:18 for 48.0 kHz stereo;
(2^32 - 1)/44100 = ~27:03:12 for 44.1 kHz stereo.
In reality, wdmaud.sys doesn't provide a TIME_SAMPLES position at all, only a
32-bit TIME_BYTES position, from which wdmaud.drv derives TIME_SAMPLES:
SamplePos = (BytePos * 8) / BitsPerFrame,
where BitsPerFrame = Channels * BitsPerSample,
Per dom\media\AudioSampleFormat.h, desktop builds always use 32-bit FLOAT32
samples, so the maximum for TIME_SAMPLES should be:
(2^29 - 1)/48000 = ~03:06:25;
(2^29 - 1)/44100 = ~03:22:54.
This might still be OK for typical browser usage, but there's also a bug in the
formula above: BytePos * 8 (BytePos << 3) is done on a 32-bit BytePos, without
first casting it to 64 bits, so the highest 3 bits, if set, would get shifted
out, and the maximum possible TIME_SAMPLES drops unacceptably low:
(2^26 - 1)/48000 = ~00:23:18;
(2^26 - 1)/44100 = ~00:25:22.
To work around these limitations, we just get the position in TIME_BYTES,
recover the 64-bit value, and do our own conversion to samples.
