-Added optional post_split FIFO.

Read back BG settings after it has been enabled, to check that BG enable is recognized in the dp_clk domain.

Excluded libs are not compiled but are mapped to work to avoid compile error when mentioned in the LIBRARY clause.

-merged transpose generics in g_reorder_seq 

- removed unused constants 

- Added record for transpose generics

Ported tc_mmf_wpfb_unit.py and tc_mmf_wpfb_unit_functional.py to RadioHDL because of used data file paths.

SVN copied tb_mmf_wpfb_unit.vhd and used modelsim_copy_files to copy the data files to the build directory.
