Obtain all test parameters from the configuration files. The defaults
are defined in the pcm-test.conf file. The test count and parameters
may be variable per specific hardware.
Also, handle alt_formats field now (with the fixes in the format loop).
It replaces the original "automatic" logic which is not so universal.
The code may be further extended to skip various tests based
on the configuration hints, if the exact PCM hardware parameters
are not available for the given hardware.

In preparation to adopting a better, more comprehensive approach to
adding the coverage that was just added using some changes from Jaroslav
which were sent at the same time the recently added improvements were
being applied drop what was applied. This reverts:

The values in the one example configuration file we currently have are the
default values for the two tests we have so there's no need to actually set
them. Comment them out as examples, with a rename for the tests so that we
can update the tests in the code more easily.

This initial code does a simple sample transfer tests. By default,
all PCM devices are detected and tested with short and long
buffering parameters for 4 seconds. If the sample transfer timing
is not in a +-100ms boundary, the test fails. Only the interleaved
buffering scheme is supported in this version.
The configuration may be modified with the configuration files.
A specific hardware configuration is detected and activated
using the sysfs regex matching. This allows to use the DMI string
(/sys/class/dmi/id/* tree) or any other system parameters
exposed in sysfs for the matching for the CI automation.
The configuration file may also specify the PCM device list to detect
the missing PCM devices.
v1..v2:
- added missing alsa-local.h header file
