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.
