mpegaudiodsp: Change type of array stride parameters to ptrdiff_t
...
This avoids SIMD-optimized functions having to sign-extend their
stride argument manually to be able to do pointer arithmetic.

mpegaudio: move ff_mpa_enwindow to a separate file
...
This table is used only by mpegaudiodsp and mpegaudioenc. Separating
it allows dropping some dependencies from mpc[78] and qdm2.

Fix ff_mpa_synth_filter_fixed() prototype
...
The prototype should use the same typedefs as the definition, or it
will fail where int32_t is not int (DOS apparently).

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.
