This patch avoids the need to main SOF ABI version information in
Matlab/Octave file eq_get_abi.m for equalizer tools. The ABI
header is fetched via new "-p" command line option for sof-ctl.
The BSD 3 clause copyright text is also updated to new short style.

The existing IIR response names are not all upper case. This patch
removes the conversion to upper case to be able to automatically
generate the topology m4 syntax example equalizers.
Without this patch run of example_iir_eq.m script causes successive
topologies build to fail.

This patch fixes the wrong file path to output example EQs and places
an identifier string to high-pass responses used in topology embedded
filter setup. The identifier is needed to correctly refer in topology
to right response when there are several similar type EQs in the
topology e.g. two separate IIR filters.
A new 16 kHz rate high-pass filter export is added into the script to
be used in voice pipelines.

This patch replaces all the filter coefficients to avoid the
unpleasant effect of samples saturation that the previous 0 dB max.
gain scaled coefficients could cause. The saturation of transients
may still happen but it should be more rare.
The filter coefficients scaling is changed from fixed pass band peak
align (to 0 dB) into DC gain controllable via new parameter gain in
src_param.m.

This patch updates the provided example responses as data for
sof-eqctl and in the include files for topologies. The updates into
Matlab scripts are included also. The FIR and IIR example script is
updated to contain all examples.
The patch includes also a bug fix into IPC handler where the check
against SOF_IPC_MSG_MAX_SIZE is off by one and caused it to reject
all set data commands (to the EQs).

This patch adds 50 kHz into SRC generator script for std and tiny
profiles. The src generator script is cleaned up and the default
conversion matrix is moved into caller script for easier maintenance.
The plots appearance is improved and the generated coefficients code
look is improved to pass the git pre- and post-commit script
requirements.
The SRC test bench scripts are updated for changed locations. A SRC
playback topology is used for test bench and real device usage.

This patch adds into filter tools retrieving of ABI version from a
single function (a quick solution) and updates all configuration
data tools to apply the user ABI header.
The confusing platform_max_channels struct field is renamed to
channels_in_config (the EQ channel map) that creates many updates. The
EQ response plot title is fixed.
Finally new functions to decode IIR and FIR settings blobs is added.
