Updating all python QA programs in gnuradio-core to output XML files.
Also fixed gr_unittest.py to print to the screen and fail make check properly if there's an error.
Need to find a way to use XML runner with main() to fail make check and output to screen, too.
Merged r7001:7035 from jcorgan/t202 into trunk. Implements ticket:202, converting qa code in core to new top block code.
Three issues exist and have been separately logged:
qa_bin_statistics.py - ticket:199qa_rational_resampler.py - ticket:210qa_stream_mux.py - ticket:211...
Updated license from GPL version 2 or later to GPL version 3 or later.
