96f02a9aa9 is_codec_thread() is not needed anymore since PCM buffer calls other than volume level are no longer made by the voice thread.

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. Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible.

56dd75d204 Purge buffer and codec APIs existing exclusively in support of mpa.codec and fix that to not require them: buf_get_offset and ci.advance_buffer_loc. Sort APIs; everything must become incompatible. :(

7d2ab2df5f Remove malloc_buf references from playback.c since it's no longer used for anything and align the codec slack space buffer that is now use as the malloc buffer.

cc889e9d60 Change the thread api a bit. 
* Remove THREAD_ID_CURRENT macro in favor of a thread_self() function, this allows thread functions to be simpler.
* thread_self_entry() shortcut for kernel.c.

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.

b15aa47c56 All kernel objects in code shared amongs targets (core, plugins, codecs) should be declared SHAREDBSS_ATTR as any core could potentially touch them even though they seem only to involve threads on one core. The exception is target code for particular CPUs where proper allocation is fixed. playlist.c was a little odd too-- use one mutex for the current playlist and a separate one for created playlists (still pondering the necessity of more than one).

7345ac124e Submit FS#11918: Add 2 more codec types to be able to differentiate between AAC / AAC-HE and MPC SV7 / SV8. Additionally handle ATARI soundfiles in get_codec_base_type() as intended.
