Support for playback of atrac3 audio in rm, in sim. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22311 a1c6a512-1295-4272-9138-f99709370657

atrac3.c
Submit interim version of FS#10565. Performance optimization of atrac3 decoder for ARM. Introduce ASM routines for multiplications and two synthesis loops, refactured parts of synthesis and windowing. Speeds up decoding by a factor of 2.4 on PP502x. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22548 a1c6a512-1295-4272-9138-f99709370657

atrac3_arm.S
#endif
Sync codeclib bitstream code with upstream ffmpeg code. Build ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code. Speeds up cook decoding by 2-3% on h300 and flac by 25% on h300, also speeds up flac decoding by 2% on c200 (decoding speed of cook on c200 is unchanged). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27430 a1c6a512-1295-4272-9138-f99709370657
