ef3e129b65 Much simpler implementation of large virtual sector support, not needing larger sector buffers and not touching file.c at all. secmult is simply used to normalize all sector counts to 512-byte physical sectors. * Moved MAX_SECTOR_SIZE definition to config-*.h, and enabled it for iPod Video only. MAX_SECTOR_SIZE now only enables checking for alternate disk layouts due to sector size (as iPod Video G5.5 is presented as having 2048-byte _physical_ sectors to the PC). Large virtual sector support in fat.c is always enabled.

ae66c2b9ee Add support (runtime detection) for 2048 bytes/sector filesystem. 
Large sectors are enabled for iPod Video (including 5.5G) only. Might
still cause FS corruption (however, unlikely), so beware! Based on
FS#6169 by Robert Carboneau.

2436dbabe7 Update dircache startcluster at file close when writing. Fixes bug when creating small files (dircache startcluster remains 0 because fat write doesn't occur until close).

ab78b04680 Implemented directory caching. No more waiting for disk to spin up while 
browsing when cache is enabled (system -> disk -> enable directory
cache). Cache building on boot is transparent except the first boot.
