483c40285b Notify the buffering thread when a handle is added, so it can go into filling mode. This is some sort of a replacement for the ATA idle callback. It will interrupt an ongoing buffering process (buffer_handle), but not for long enough to be a problem. 
Should fix a problem reported by Dave Hooper where inserting tracks into the playlist would flush the buffer and not refill it, sometimes causing the inserted tracks to be skipped.

659fe5a35b Fix FS#6215 (player crashes after trying to resume deleted music file). As mentioned in the lastest comment, the problem was in trying to resume at an offset larger than the size of the file following the one that was deleted. This revealed a crash in the buffering code, which gets a fix, but we also need to intervene earlier in the track loading so that the track that gets played will be from its start.

ecec94043d Check that the pointer isn't NULL before dereferencing it, just to be safe and to allow using bufgetdata to know how much data is available. Also remove a few trailing spaces.

774fd19c37 Checking for total free buffer space isn't correct. What we need to check is the space available for the particular handle we want to rebuffer.

e24454f8b3 Buffering callbacks rework. There is now one callback for all the events that can occur. Callbacks are now registred only once instead of being removed after having been called. 
Fix FS#8092 by flushing the audio when a rebuffer is needed.
Also add some comments here and there.

398d9fd8b4 Hopefully the last word on getting rid of yield_codecs loops (cut read chunk to 16kB). Sansa ata driver also didn't yield enough so buffering would starve other threads. Bump priority of audio thread to keep UI more responsive.

9d4bed7ff0 Album art support. Based on FS#3045, but heavily modified to adapt to MoB and for cleanness. 
The cover pictures are loaded from external bitmaps. JPEG and embedded art are not supported. The pictures will only be drawn on the main display. There is no resizing but it is possible to specify the WPS bitmap size in the bitmap names (e.g. cover.100x100.bmp).
The bitmaps are stored in the main buffer and read directly from there. Currently, duplicate bitmaps will simply be present several times in the buffer, but this will be improved.
To enable for a target, #define HAVE_ALBUMART in its config file.
For more information, see the wiki page: http://www.rockbox.org/wiki/AlbumArt.

1df1e7b0c7 Remove unused conf_preseek from buffering.c and all of its accountraments. This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements. It may also belong in buffering not playback, haven't decided for sure
