Add floating point volume handling to AudioMixer
Use floating point volume in AudioMixer mixing when floating
point input is used with the new mixer engine.
AudioResampler is updated to take floating point volume to match.
Both legacy integer and floating point mixer engines work.
For now, integer volume is used when the new mixer engine
runs in integer input mode, for backward compatibility with
the legacy mixer. The new mixer engine will generally run in
floating point input mode. When the legacy path is removed,
the integer volumes will be removed.

Replace int bitDepth with audio_format_t in Resampler
Remove mBitDepth from class (not used).
Replace with audio_format_t in factory method to distinguish
between float and pcm 16-bit.

Update test-resample to handle multichannel
Option -c # specifies number of channels (mono default).
Option -s to specify stereo is removed (-c 2 replaces).
Option -h to specify WAV header is removed (WAV is now default).

Improve dynamic audio resampler filter generation
Improve dynamic audio resampler filter generation speed by 2x.
The resulting filters should be the same (excepting roundoff).
Also added check for upsampling sample rate changes to share
previously generated filters.
Modify the profiling to improve output format and sampling result
reliability.

Add ability to read .wav files to test-resample
Previously test-resample could only read .raw files, and the input
sample rate had to be specified. Now the input sample rate is derived
from the input file. This also allows us to read 8-bit PCM files,
and other formats such as floating-point in the future.
However, the ability to read raw files is lost.
A workaround is to use sox or equivalent on the host.

Fix several test-resample BufferProvider bugs
Previously getNextBuffer always returned the same data address over
and over. Now it correctly returns the right portion of the input buffer.
Previously getNextBuffer always returned the total number of frames in
the input, which might be larger than the size requested by the caller,
and/or larger than the number of remaining input frames. It also always
returned successfully, even when there should be no frames available.
This violates the contract for getNextBuffer. Now getNextBuffer will
return the maximum of the number of frames requested, and the number of
remaining frames available. If that maximum is zero, getNextBuffer will
return an error instead.
Previously releaseBuffer would silently allow releasing more frames than
were actually gotten, which violates the contract for releaseBuffer.
Now releaseBuffer checks for this and logs a message if it happens.
Add 'v' (verbose) option to log buffer provider calls.
