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.

ed492b61db Add an HE-AAC v1 decoder. 
A large portion of this code was orignally authored by Robert Swain. The rest
was written by me. Full history is available at:

84dc2d8afa Remove DECLARE_ALIGNED_{8,16} macros 
These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

981b8fd777 Don't lock the channel output configuration based on the first value seen for 
non extradata formats. Instead lock it only after the successful decoding of a
frame. This fixes issue 999.

6308765cb5 Ignore subsequent channel configurations after the first in an AAC file. The 
current code doesn't handle them properly, and they are a dubious construction
at best.

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_".

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