396b73c7f7 ac3dec: Remove unneeded context variable, num_cpl_subbands. It is also 
not needed for spectral extension or enhanced coupling since it is
redundant information, so I am removing it from decode_band_structure()
as well.

bad5537e2c Use full internal pathname in doxygen @file directives. 
Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.

987903826b Globally rename the header inclusion guard names. 
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
