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.

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.

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.

mpegaudio: call ff_mpegaudiodec_init_mmx() only from float decoder
...
The mmx code is floating-point only, and this function does not know
from which decoder it is called. Without this change, the integer
decoder only "works" because the size of the context struct is smaller
in this case, and the mmx init function writes the function pointer
outside the allocated context.
Fixes issue 2054.
