115b2bf68d Calculate the nibble/word/dword index of the FAT entry in the sector 
centrally in getFATblock.

f6716cd74b "clussec" can be of CLUSTER size if we divide by an adjusted "words per 
sector"(FAT16), or "dwords per sector"(FAT32) value instead of multiplying
it first. For FAT12 the *3/2 works out a little differently: here we
first multiply by 3 and then divide by the number of "nibbles per sector".

bb7f10fafc Reverted bad optimization -- (unsigned)Cluster2 may have the high 4 bits set 
with LONG_LAST_CLUSTER.

490a27b857 Some of Arkady's fattab optimizations -- the others only increase the kernel 
size for Watcom.

0e0abcd685 Added explicit (UWORD) type casts to avoid compiler warnings and sometimes 
save a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of bytes to
be added to SI.

4f1a117069 * FAT32 kernels should ignore the upper word of the cluster number for 
FAT16 partitions (just like FAT16 kernels do)
* added extra checks to make sure that invalid FAT entries are never
  followed
* made put_console() public to be able to print a message in case of
  FAT corruption
* some small optimizations and header cleanups (some suggested by Arkady)
