Add IO priority handling. Currently all IO has equal priority, except the dircache scanning thread which is lower. This fixes the slow boot problem for me, with the added benefit that actual audio playback also starts faster.

Lots of the changes are due to changing storage_(read|write)sectors() from macros to wrapper functions. This means that they have to be called with IF_MD2(drive,) again.
