aaudio: loopback test improved
Check to make sure input capacity is large enough.
Add -B option to set input capacity.
Handles variable callback size better when setting up the
loop for Legacy mode.
Narrower impulse.

aaudio: fix loopback test, track magnitude drift
Loopback test was still reporting some glitches.
These were false alarms due to:
* starting input before output causing an overflow
* not waiting for the input to reach equilibrium with the output
* detecting slow drift in magnitude as a glitch
I changed the logic for setting up a test
and track slow changes in magnitude.
Now the rare glitch seems to be a real glitch.

aaudio example: fix loopback test
Support both I16 and FLOAT format.
Silence output at beginning when skipping buffers. Was sometimes spewing noise.
Print more information when it fails so we can debug the failure.
Fix getting framesPerBurst from wrong stream.
Track when read gets too few frames.

aaudio_loopback: use WAV files, reject low gain
Save recording in a WAV file instead of a RAW file.
Add a test mode that reads a WAV file, for debugging auto-correlation.
Cleanup printed reports.
Discard more input buffers at beginning.

Use -Werror in frameworks/av/media/libaaudio
* Remove unused local variables, labels, functions, private fields.
* Fix warning of unused return result.
* Use template functions in .h file to avoid warning of unused static functions.
