Does away the statically-allocated track list which frees quite
a fair amount of in-RAM size.
There's no compile-time hard track limit.
Recommended TODO (but not right away): Have data small enough use
the handle structure as its buffer data area. Almost the entire
handle structure is unused for simple allocations without any
associated filesystem path.

HAVE_IO_PRIORITY was defined for native targets with dircache.
It is already effectively disabled for the most part since dircache no
longer lowers its thread's I/O priority. It existed primarily for the
aforementioned configuration.

It is trivial to obtain all required information from the allocated
handles without maintaining global indexes. In fact, it is less
complicated and increases general thread safety.
Other miscellaneous changes (some are nice to do at this time due to
required alterations, with some particularly more relevant than others):
* Handle value 0 will no longer be returned as a valid handle but all
failures will still return a negative value. Creates consistency with
buflib and removes the need to explicitly initialize them.
* Linking a new handle is delayed until explicitly
added by the code that called add_handle, keeping it invisible
until every operation succeeds, which is safer thread-wise. If anything
fails, the handle itself may just be abandoned rather than reqiring it
be freed.
* Dump the special handling to slow buffering when the PCM buffer
is low that calls PCM buffer functions. It doesn't seem to help much
of anything these days and it's a bit of a nasty hack to directly
tie those bits together. It can of course be put back (again!) if
there really is a need for it.
* Make data waiters ping the buffering thread more than just once if
the request is taking too long. Somehow I figured out how the requests
could get forgotten about but can't remember why months later after
making the change in my branch. :-)
* Neaten up some code by using (inline) functions and packing down
parameters; remember handle allocation and movement attributes in the
handle itself rather than figuring it out each time they're needed.

It's not useful to do it since you need to write back the code to disk to be able to load it from memory, it also requires writing to an executable directory.
Keep it for the simulator for the sake of simulating.

Playback now has a few albumart slots. Anything (most importantly: skins) can obtain such a slot.
The slot has fields for the size which is passed to bufopen then to image_load to buffer the albumart with the proper size.
Currently there's 1 slot. We can increase it for remotes if we want. Custom statusbar will increase it.

Fix FS#8092 by flushing the audio when a rebuffer is needed.
Also add some comments here and there.

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.

buffering.c and buffering.h implement the new buffering API. playback.c is translated to that API. For more information about the whole concept, see http://www.rockbox.org/wiki/MetadataOnBuffer.
There should be no major visible changes, but most existing bugs remain (though fixing them should be easier now that playback.c is a bit less complex) and there probably will be new ones. Please report any problem!
Next step is to adapt cuesheet support, which is partly disabled here, and of course fix as much bugs as possible.
