Diego Biurrun aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name. 
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

Mans Rullgard 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.
