AudioFlinger: Fix Tee logging
1) Fix bad WAV files for tee sources that aren't 16 bit PCM.
2) Allow multiple RecordThread tees instead of one.
3) Allow dump from non-fast MixerThreads (e.g. deep buffer).
4) Parallelize tee dumping for improved concurrency;
dump outside of AF lock.
5) Async dumping to allow dump to be issued in time critical code.
6) Improve file naming to distinguish record vs playback tracks,
threads, and dump reason.
7) Allow Tee insertion anywhere in code with global running
Tee management.
8) Increase resolution of filename time to msec avoid file overwrite.
9) Dump track data upon removal from active tracks to improve
timeliness of dumped data.
10) Dump tee data on tee destruction.
11) Refactor Tee code out of AudioFlinger.cpp; minimize footprint.
AudioFlinger enabling code requires Configuration.h define TEE_SINK;
this is disabled, hence avoiding regression risk.
Test: Enable tee log, repeatedly call dumpsys, examine files.
