Bug fixes in matrix driven test and some minor changes in perf media test.

Bug fixes in matrix driven test and some minor changes. Also, adding
media_matrix_data_public.csv for videos that are in
trunk/deps/avperf/{bear,tulip}. 

Bug fixes includes:
* CSV file abnormality
* the order of returned tuples in _GenerateMediaInfo and LookForMediaInfoInCompactFormByNickName was incorrect
* not recognize the second column of CSV as tag
* par_filename was not set in the case of matrix driven test. 

Added features:
* -c and -z option to control the number of tests

Please be descriptive and specific and the CL title and description.
The rule of thumb is that a chrome/chromeos developer unfamiliar with your work
should be able to make some sense just by looking at your commit log.
In particular, mention 'media perf' somewhere. 'Bug fixes in matrix driven test
and some minor changes' doesn't help much.
