dfff938dff Get rid of useless playlist probing and fix up some data types.
Playback checked the files' presence before attempting to buffer
the track. Just get rid of that and save an extra open/close call.
It will find out if the path is bad when the metadata fails.

Fix some size_t/off_t conflation. No need to update plugin version
because no plugin actually uses bufopen().

c1a01beded Playback: Move internal track list onto buffer
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.

5b08f1a5b9 Remove I/O priority. It is harmful when used with the new file code.
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.

36615815bf Buffering: Remove buf_ridx and buf_widx; these data are verbose.
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.

5a8f5b8330 Provide a reasonable fix for FS#12093 - Playback hanging after codec/playback rework. Also, get rid of an impossible buffering case (BUF_USED is always less than buffer_len) and remove a buffering API that is not used anywhere and shouldn't be needed (plugin API has to be incompatible).

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.

86cab2e27a Disable buffering codecs (and code generally) on RaaA.
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.

e9c10189e9 Rework albumart buffering internally to allow for mutliple albumart sizes.
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.

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.

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

dcca586a9b Improve upon my hackity hack from before by separating audio into two types: that which may be large and can be streamed and that which is small and cannot be streamed. While modifying types, allow codecs to split across the buffer wrap and dig out/move around the code that reads a codec off of the buffer to facilitate that simple sounding change.

3e3c43c747 Finally commit Metadata on Buffer!
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.
