ecd9bcf3cb Commit FS#10605 - stable playback on low memory swcodec targets by Matthias Schneider. Should allow stable playback on targets with less then 4MB of RAM and sofware decoding such as the Sandisk Clip, c200v2, m200v4 and probably others. Fixes several problems in buffering that occured when the files to be buffered weren't much smaller then the ring buffer size. Fixes a bug where move_handle would corrupt the audio buffer when trying to copy a handle that both wrapped around the highest address in the ring buffer and overlapped part of the source and desination ranges. Moves the decision in playback.c about when to update the current track handle from audio_check_new_track to after the metadata has been buffered. Corrects several other minor pieces of code. I've logged about 100 hours without a crash on various players with this patch but its possible it breaks some combination of players and features I haven't thought to test.

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.

* Move strncpy() from core to the pluginlib
* Introduce strlcpy() and use that instead in most places (use memcpy in a few) in core and some plugins
* Drop strncpy() from the codec api as no codec used it
* Bump codec and plugin api versions

216424a27f Fix the lock contention stall during cover art load, by adding a separate modify mutex for the buffer. Operations that modify contents of a buffer entry can still proceed, but ones that add or remove buffer entries, or move them 
in memory, will still block. Some members of struct memory_handle also need an earlier init in bufopen to make sure that buffer stats aren't trashed.

8cfbd3604f Use cookies for thread identification instead of pointers directly which gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required.

3625be4803 Fix FS#9319 and its (probably) duplicate, FS#9576. They both describe the boost remaining active after a change of the dynamic playlist, an issue added in r17109. 
The fix is to notify the buffering thread whenever an ID3 handle is created via bufopen (as is done in the other cases of bufopen).

2f8a0081c6 Apply FS#9500. This adds a storage_*() abstraction to replace ata_*(). To do that, it also introduces sd_*, nand_*, and mmc_*. 
This should be a good first step to allow multi-driver targets, like the Elio (ATA/SD), or the D2 (NAND/SD).

4e2de44b44 A rather big change to how tracks are loaded: there are now two parts to the process and metadata loading is done by the buffering thread (except for the first unbuffered track). The audio thread now calls audio_load_track, and once the metadata is loaded, the buffering thread sends an event which will make the audio thread call audio_finish_load_track. This one then takes care of the rest of the loading. 
This method makes skipping noticeably faster for unbuffered tracks, and especially backwards.

27cf677339 Add a complete priority inheritance implementation to the scheduler (all mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed.

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.
