This patch updates the locations of "make install" libraries default
install locations into shell script to run SRC test cases. The script
also now prints the used LD_LIBRARY path to ease setting up code
debugging.
The segfault of testbench executable is fixed by returning a valid
pointer reference instead of a NULL from test dummy function
arch_schedulers_get(). The rest of testbench version of schedule.c
was also updated to be like the current real version module.
Finally in the testbench.c main the file names string pointers are
initilizated to null as well as the word length parameter to avoid
a segfault if executable is started without command line arguments
to see the usage help text.

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.

Currently SRC returns error when 0 size input or output data is detected
and pipeline interpretes this as fatal xrun error. This could happen
for example when host dma has no time to fill in first iteration of
samples. So instead of error, return PPL_STATUS_PATH_STOP as SRC in the
middle of the pipeline should handle also occasional 0 size data.

This patch avoids the need to main SOF ABI version information in

This patch adds command line option "-g" to generate and with help
of options "-o <file>" to store the current ABI version header data
into file. Use "-b" to change the default CSV format to binary.
It is used by external tools to create configuration data blobs for
SOF audio processing components.
The parameter for size is the configuration data payload size with
the size of sof_abi_hdr struct excluded. It does not impact the
the length of printed header. It just places the length into the
correct location in the header.
This patch also fixes the permissions of file output. The mode
need to be provided for open() to avoid having no access to
created file and allow overwrite of existing file.

This patch implements the new version of EDF scheduler.
This is the first basic implementation, which can be easily extended
in the future.
Previous implementation had two major flaws:
- Tasks could only be preempted based on the interrupt level on which
they have been scheduled, so it was limited based on the hardware.
- This led to the system not fully utilized, so we could never achieve
full EDF functionality.
The new implementation uses only one software interrupt and allows for
dynamic context switching between different tasks based on the deadline.
Also for some cases priority is taken into consideration e.g. for idle
and almost idle tasks, which don't have deadline at all and should be
executed only if the system is free. All other normal tasks should have
the same priority. Task chosen to be run is executed on passive level,
so automatically can be preempted by every interrupt. Every task has
its own private stack on which current context is saved and restored
if needed. Note that main firmware loop is task scheduled with
idle priority, so it will be executed only after every other task
is completed.

This change introduces new DAI driver ops: get_handshake and get_fifo.
They shall be used to obtain DMA handshake and FIFO address information.
The motivation for this is the required by ALH ability
to retrieve this information during runtime,
based on parameters passed to us by the kernel/driver.
The DAIs no longer have to have hardcoded platform data (fifo/handshake),
the computation of those now may happen directly
in the DAI driver implementation.
