4f84e728da aacdec: Reduce the size of buf_mdct. 
It was doubled in size for the LTP implementation. This brings it back
down to its original size.

fe2ff6d247 Separate format conversion DSP functions from DSPContext. 
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

bb2d8e9f05 aacdec: Rework channel mapping compatibility hacks. 
For a PCE based configuration map the channels solely based on tags.
For an indexed configuration map the channels solely based on position.

This works with all known exotic samples including al17, elem_id0, bad_concat,
and lfe_is_sce.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

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_".

b0f5852a13 Use ff_imdct_half() and vector_fmul_window() for IMDCT and windowing. Reduce 
buffer sizes accordingly. This produces a ~10% overall decoding perfomance
