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.

2358fabb70 Optimization to latest aac decoder changes. Significantly reduce loop count in m4a_check_sample_offset() during standard playback. Before this change the loop count increased with each decoded chunk and for each frame.

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.

11b7a4fb26 Add a safety check in the resume seek code, just in case.

ee6a74e7e3 We seeked one chunk too far when resuming m4a files.

411023c6be Rework m4a seek/resume code. Seek/resume does now also work properly with files having sample_to_chunk of 1 or 2.

008c368c87 Commit first part of FS#10832 by Juliusz Chroboczek. Allows playback of unstreamable AAC/ALAC files by stepping through the file to find the index, potientially rebuffering. This is likely to impose a battery life hit on files which are unstreamable and not much smaller then the buffer, but should not impact streamable files at all.

d6ae8edc13 Commit both patches in FS#10833 - Protect against division by zero in AAC (mp4) codec by Juliusz Chroboczek. Adds some return value checking so that faad errors don't crash rockbox when decoding broken or unsupported files.

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles. 
Many #include lines adjusted to conform to the new standards.
