* app/tile_swap.c
* app/tile_swap.h
* app/tile_manager.c
* app/tile_manager.h
* app/pixel_region.c
* app/pixel_region.h: asynchronous swapin on systems with pthreads.
This version is not at all tuned, and the only interface which makes use
of it now is pixel_region_{g,s}et_{row,col}. Other functions which know
ahead of time the area that they will be needing can request that it be
asynchronously swapped in via the pixel_region_get_async() function.
Compiles and survives basic testing.
* app/tile_swap.c: made the g_message errors a little smarter instead
of popping up a ton of dialogs
* app/layer.c
* app/channel.c
* app/gdisplay.c
* app/gimprc.c: some code cleanups

Modified tile swapping to preswap dirty tiles, using a thread if
threads are enabled in configure or a gtk_timeout if they're not. The
code appears stable but could use improvement. Be careful when
working in here; there are four sets of semaphores and getting the
locking wrong will cause deadlocks or tile corruption. I'll try to
write up a document describing what's going on in here sometime soon.
