918d0584a4 mpegaudio: move some struct definitions from mpegaudio.h
These structs are only used in mpegaudiodec.c, so move them there
and remove no longer needed #include lines from mpegaudio.h.

c4f5c2d6f4 Move some mpegaudio functions to new mpegaudiodsp subsystem
This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

4bac1bbc3b mpegaudio: add _fixed suffix to some names
This adds a _fixed suffix to the fixed-point versions of things
with both float and fixed-point variants.  This makes it more
consistent with other dual-implementation things, e.g. fft.

92ea249d7d mpegaudio: remove OUT_MIN/MAX macros
These macros are no longer needed after the s32 output was removed.
Change the relevant code to use av_clip_int16() instead of using
explicit limits.

6bb6fb05ba mpegaudio: remove CONFIG_MPEGAUDIO_HP option
The low quality mode is off by default and never tested.  The high
quality mode is also plenty fast enough.

3a2e80ecbc mpegaudio: remove CONFIG_AUDIO_NONSHORT
This fake option cannot be enabled by normal means, and the
floating-point decoder should provide the higher quality this
option presumably was intended for.

This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

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_".
