The fprintf() command prints only "#!/bin/sh". For some reason
this has been ignored by interpreter but as clear error it is
better to fix.

The changes to scripts/host-testbench.sh and earlier to process_test.m
have unintentionally dropped valgrind run from test.
This patch enables valgrind for process_test.m runs and fixes
issue in test run octave side function to silently ignore
error about failed shell command. Normally test fail when there
is no data or incorrect data, but a valgrind failure with correct
test output was passed.
Valgrind output becomes visible if testbench run trace stderr
redirection to file is disabled. If not done valgrind error would
stop the test but the analysis would not be printed to console.

This patch adds to chirp test (executed first usually) plot of

The gaussian (or other normal distribution shape) dither impacts
too much 16 bit signals. The triangular probability density
function (TDPF) is a sufficient compromise between added noise energy
and de-correlation of PCM samples.
This change improves for 48 kHz 16 bit audio measurement the THD+N
from -62.6 dB to -73.6 dB.

The trace print slows down the test a lot while the testbench
trace output is not needed usually in these audio quality
tests. The test script can set .trace to redirect trace to a file
that is also a lot faster than scrolling the trace in Matlab
or Octave shell.

This patch adds to command line switch -n for output channels count.
Existing -c is for in channels, new -n is for out channels count. Out
channels count is same as input if -n is not present. Switch -q is
added to quiet the trace output if it is not needed.
The Matlab language test scripts for components are updated to use
the -t config.sh interface of comp_run.sh. It allows more flexible
control of input and output streams.

The main change in this patch is to allow process_test to use
frequency dependent masks for frequency response and THD+N. It
allows tests with pass/fail criteria for components like EQs
and DCblock. SRC test not really changed but the small changes
in passing test controls are updated there as well.
In EQs tests the process test can decode the theoretical response
from setup blob. The measured frequency response is compared to
that.
The test print and plot output look is improved for nicer reports.
The runtime plots opening is disabled for batch mode operation
but the plots now appear to test output directory in png format.

The criteria of overall -3 dB RMS attenuation was too tight
for sample EQ responses to pass. With new -6 dB criteria the
used EQ loudness responses do not trigger error.
The chirp test is only a quick generic component health check so this
is not critical. The other AES17 tests will catch minor characteristic
changes.
The other changes are cosmetic and improve result print and plot
output look.

Chirp test signals confused the test signal begin marker position
seek and caused false test fails. The test stimulus may produce
stronger cross correlation level than the actual marker. Also
the check omitted that the cross correlation max could be negative
so the test was changed into power domain and use first/last
cross correlation peak above threshold as test begin/end position.

This patch adds a shell script sof_test_perf.sh that measures
gain, frequency response, and total harmonic distortion plus
noise for a remote device.
Matlab or Octave is needed. The shell script launches by default
Octave to process the signal generation and test results analysis
scripts.
The remote device must be set to be accessible by ssh without
passwords. An external high quality USB sound card is recommended
as analog interface to connect to test device's analog interface.
The configuration file sof_test_perf_config.m must be edited for
the remote device's user account, audio device, audio format, and
capture sound card audio device, and audio format.

The tests created lot of unnecessary fails when testing with S16_LE
format. The test pass criteria for THD+N, DR is relaxed for tests
with 16 bit data.
Since the gain of SRC conversions was lowered to -1 dB the test
case for gain need to be updated. The gain is retrieved from
src_param() function. An exception is added for FS1 == FS2 case
when data is passed through. In that case expected gain is 0 dB.
The frequency response measurement grid does not necessarily cover
the exact upper frequency of pass-band. Therefore the min. upper
passband frequency is scaled by 0.99. This avoids measurement
technique related fails in test.
The chirp spectra test case was updated to use for RMS level criteria
for testing the level of signal. The peak level was less robust and
caused unnecessary test fails.
The option to not open plot windows during test is set. It improves
speed of test and avoids display clutter.
