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.
