This patch adds checks and errors for fopen() failures. The check
is useful with setup scripts paths changes. Aborting the script
avoids the errors in blob exports to be missed.

The sof_ucm_blob_write.m is an updated copy of blob_write that
exports binary blobs with header that is suitable for ALSA UCM's
cset-tlv command. The UCM requires binary files so the default
binary export is changed for every component setup script to this
format.
The ASCII decimal numbers .txt format export remains suitable for
sof-ctl tool.

This patch modifies script example_dblock.m to create in
addition to existing default coefficients blob with parameter
R=0.98 a set of blobs those provide (-3 dB) cut-off frequencies
20, 30, 40, 50, 100, 200 Hz for 16 kHz and 48 kHz for various
usages. Human understandable parameters for blobs helps to select
the configuration for the needed dcblock usage.
The parameter value R for given frequencies is calculated
with iterative function dcblock_rval_calculate(). A closed
form equation might be possible to derive from the transfer
function. If such is found this function can be replaced with
quicker equation -- or with more advanced faster converging
iteration.
The topology blob export functions are also modified to add
comment line for exact build command.

This patch re-structures function example_multiband_drc() to
let it generate multiple differentiated configurations. The
computation of blob is moved to new function export_multiband_drc().
The script now generates default (same as before) and pass-through
blobs.
Inside the function the paths for tplg1 and tplg2 are updated as
well as locations of data blobs for sof-ctl. The run of export
function creates blobs for both tplg1 and tplg2 with SOF IPC
versions three and four.
check_create_dir() common function is added to avoid error with
missing directory for export and for warning message about
already existing directory that just using mkdir() would do.

This patch enables running example_drc.m script with Matlab.
The endifs are changed to end. And mixed usage of endfunction
and end is corrected to just end. The unnecessary
semicolons from function declarations are deleted.

This patch changes a bit structure of example_drc to export
conveniently several different blobs. The changed script
exports configurations blobs for disabled and enabled mode.
Two functions for IPC4 and topology2 compatibility are
generalized from EQ to common directory. The EQ and other
tools will be updated to later to use the common get_abi()
and tplg2_write() functions.

This commits adds the scripts to generate the bytes control blob
for the DCB. It also provides some generic scripts to convert
valid binary blob to a csv or binary file (usable by sof-ctl)
or an m4 byte control topology file.
This commit adds two new folders under tools/tune
- dcblock: scripts to generate the blob in Octave
- common: scripts to convert any generic blob to a config file.
