180bf988bc mp3on4: create a separate flush function for MP3onMP4. 
The correct decoder private context needs to be used.
This fixes mp3on4 playback and seeking in avplay.

53c8443ad2 mp3on4: ensure that the frame channel count does not exceed the codec channel 
count.

This also allows for checking output data size based on the actual
number of channel instead of the maximum number of channels.

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.

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.

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.
