6f392693b8 AAC: Another gapless fix, this one for the end of the file. The real size of the last frame was lost in r29727, as indicated by Yusaku Inui in FS#12185, so bring it back. Now the decoded length of test1_nero.m4a (in FS#12185) only differs by one sample compared to Foobar2000 (Rockbox has one more leading sample, for some reason). Also moved a few lines to a better place.

e62b9a9aae libtremor: Implement a memory configuration for targets that don't use separate iram for codecs. 
Such targets would previously default to using the configuration for targets with small iram which uses an extra memcpy per block.
This saves 2MHz decoding a 128kbps vorbis file on the Gigabeat S and saves a bit of codec buffer.
Patch from FS#11268, also replaces patch from FS#12147.

4909e09267 FS#12141 by Sean Bartell 
Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note:
* The old MDCT has been removed.
* Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs.
* I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib.

c537d5958e Commit FS#12069 - Playback rework - first stages. Gives as thorough as possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once.

a602f46d69 Rework of libfaad in several areas. Allow removal of malloc with a new define FAAD_STATIC_ALLOC (in common.h). For now malloc is not fully removed but used by a few arrays needed for AAC-HE SBR+PS only. Reason to keep malloc is to have this amount of memory available for AAC-LC files which might require large m4a tables. The changes make the allocation routines much smaller, better centralized and allow to move duplicated code from aac.c/raa.c to libfaad. The rework includes removal of (now and former) unused code as well.

68199cc195 Major rework of the m4a parser for aac/alac playback, seek and resume support. As a result the memory consumption was drastically reduced. This allows to play several files with long duration -- especially on low memory targets. The change builds a lookup table from m4a's sample_to_chunk[] and chunk_offset[] and completely removes the allocation of the large tables chunk_offset[] and sample_byte_size[]. To be able to remove reading and allocating sample_byte_offset[] the aac and alac decoder now buffer a fixed amount of bytes for each frame. The generated lookup table is used for seek/resume and skipping bytes in empty chunks (aac decoder only). The precision for seek/resume is somewhat lower but still equals 0.5 sec for the worst case. Fixes FS#8923.

6510973223 Give playback engine better control over the codec. Codec simply follows commands and doesn't concern itself with audio state. Get track change notification in on the actual last buffer insert of the track because now audio simply waits for a track change notify from PCM on the last track and it must be sent reliably. This is still at an intermediate stage but works. Codecs and plugins become incompatible.

In switch_thread, make the call to profile_thread_stopped from an inline asm block to make sure the sp is pointing to the right place before storing the context. This apparently worked by luck with the old Gcc.
The workaround used for coldfire in the codeclib's __cyg_profile_func_enter does not work with newer gcc, however the workaround isn't needed for those so enable it only for coldfire gcc version < 4.

67efbc1387 libtremor: 
Merge in upstream revision 17375.
This removes tremor's internal ogg code and now uses libogg instead so a bunch of changes are just adjusting to the new api. Also brings in improvements to vorbisfile which fixes FS#10484.
Disabled a lot of unused code in the libogg files and moved some small functions into the ogg.h header so they can be inlined. Some small tweaks to fix warnings.

b965c24c0b ffmpeg flac does actually support up to 192k sample rates, and my test file seems to decode fine, so lets enable it. Note that using 192khz is over 6 times slower then 44.1khz on my test file, so I recommend sticking to more reasonable bitrates.

f51189fa4d Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on packed multiply instructions. Additionally, improves scheduling on arm9 and arm11 and forces cache alignment of buffers on all targets. Accuracy is slightly reduced, but still greater then 16 bit. Clip+ CPU clock required for LP2 files decreases by 13MHz and ARM11 by 18MHz. No performance or accuracy changes on armv4 or non-arm.
