Thomas Martitz 2a8eacdbfc Buflib: Make shrinking and buflib_available() smarter. 
* shrinking now considers freespace just before the alloc-to-be-shrinked,
  that means less (or sometimes none at all) is taken from the audio buffer.
* core_available() now searches for the best free space, instead of simply the end,
  i.e. it will not return 0 if the audio buffer is allocated and there's free space
  before it. It also runs a compaction to ensure maximum contiguous memory.

audio_buffer_available() is also enhanced. It now considers the 256K reserve buffer,
and returns free buflib space instead if the audio buffer is short.

This all fixes the root problem of FS#12344 (Sansa Clip+: PANIC occurred when
dircache is enabled), that alloced from the audio buffer, even if it was very
short and buflib had many more available as free space before it.

backlight.c 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). 2011-02-14 11:27:45 +00:00
