7b122fb62a alsabat: add system power management S3 test
Support audio pause/resume for playback and capture. The user can
pause alsabat playback/capture threads by sending a signal. The patch
provides a method for QA to quick test audio during system s3.

0cfe406618 alsabat: add noise detection
Alsabat reports error when noise above threshold be detected.
Use either of the options below to designate the threshold. (e.g.
if the ratio of noise to signal is 5%, the snr is about 26dB.)
    --snr-db <value in dB>
    --snr-pc <value in %>

The noise detection is performed in time domain. On each period
of the sine wave being analyzed, alsabat substracts a clean sine
wave from the source, calculates the RMS value of the residual,
and compares the result with the threshold. At last, alsabat
returns the number of periods with noise above threshold. 0 is
returned when the source is clean.

e1b7a5f376 alsabat: add a single channel sine wave generator
Add function generate_sine_wave_raw_mono(). It serves as a single
channel sine wave generator, to provide data for calculation (e.g.
for noise analysis).
The function is similar to generate_sine_wave(), but a lite revision.
It has no dependency on bat channels and target frequency, no malloc
inside, no data conversion from float to integer samples, and supports
one channel only.

4157528808 alsabat: add round trip audio latency test
Audio latency is the time delay as an audio signal passes through
a system. There are many kinds of audio latency metrics. One useful
metric is the round trip latency, which is the sum of output latency
and input latency.

The measurement step works like below:
1. Listen and measure the average loudness of the environment for
one second;
2. Create a threshold value 16 decibels higher than the average
loudness;
3. Begin playing a ~1000 Hz sine wave and start counting the samples
elapsed;
4. Stop counting and playing if the input's loudness is higher than
the threshold, as the output wave is probably coming back;
5. Calculate the audio latency value in milliseconds.

  the structure is more reasonable, the function API is simplified
  and no need file cleanup in thread loop.
  2. Replace the wav header processing lines with a general function
  (update_wav_header()), which can be reused in other sections.
  3. Add pthread_exit() for thread to exit safely in single line mode,

3bf8e79c3b bat: Avoid local signal.h file
The local header file named as "signal.h" causes mysterious compile
error when built with an old glibc.
 signal.h:27: error: conflicting types for 'sin_generator_init'
 ./signal.h:27: error: previous declaration of 'sin_generator_init' was here
 signal.h:28: error: conflicting types for 'sin_generator_next_sample'
 ./signal.h:28: error: previous declaration of 'sin_generator_next_sample' was here
 ....

This turned out to be the conflict of signal.h; namely, pthread.h that
is included before our local signal.h also includes "pthread.h".
Since our local "signal.h" has a higher priority, it gets loaded
instead of the expected pthread's one.  Then we load it again, and it
screws up.

Although it's basically a bug of pthread, it's anyway not good to have
a header file conflicting with the standard header file.  So, let's
name it more explicitly as specific to BAT, bat-signal.h, for avoiding
such a conflict.
