[autotest] audio_quality_measurement: Ignore false alarm
Ignore false alarm of "noise before/after sine wave" when it is too
close to the start/end of the sine wave.
We determine start/end of sine wave by frequency of a block.
We detect noise before/after sine wave by magnitude of a block.
The block near start/end of sine wave will have magnitude that
might be incorrectly treated as noise. Add a 0.01 duration to account
for that edge effect.
This is especially easy to seen in WebRTC loopback test because the
magnitude of sine wave is large in the beginning, and then it becomes
much smaller when it stablizes.
Also add debug message for start/end detection.
BUG=chromium:667674
TEST=run audio_AudioWebRTCLoopback test.

[autotest] audio_quality_measurement: Ignore detected noise at edge
In the beginning and the end of data, there will be false alarm noise
caused by edge effect of Hilbert transform. We should ignore them.
See the docstring of NEAR_DATA_START_OR_END_SECS for detail and example.
BUG=chromium:663616
TEST=use check_quality tool to check the quality of the file attached on
the issue.

[autotest] audio: add audio quality measurement module
Add quality measurement tools:
- Detects artifacts
-- noise before playback
-- noise after playback
-- delay during playback
-- burst/pop
- Detects scenarios
-- volume changing detection
- Noise estimation
Add audio quality measurement unittest.
