82ab61f901 lavc: use avpriv_ prefix for some mpegaudio symbols used in lavf. 
Specifically, ff_mpa_freq_tab, ff_mpa_bitrate_tab, ff_mpa_decode_header,
ff_mpegaudio_decode_header.

bde2c1c7fe mpegaudiodec: Fix av_dlog() invocation. 
Some parameters passed to the av_dlog can be either float or int, depending on
the mode the file is being compiled as.  Cast those parameters to float and use
appropriate conversion specifiers.

6f1ec38ce2 mpegaudio: clean up compute_antialias() definition 
This merges the float and fixed-point versions of the compute_antialias
function, fixes invalid array indexing, and eliminates a dead copy of
csa_table.

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.

35d597d556 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.
