This patch reorganizes heap memory usage by dosfsck and mkdosfs
to support limited-memory embedded systems - in particular, those
based on Xilinx's Microblaze processor. It also adds a few comments.

* FAT16 filesystems with 65525 clusters or more will be rejected
(Before, this was not tested for. Up to 65535 clusters were accepted
as good).
* For FAT32 filesystems with less than 65525 a warning message will be
output.
Macro MSDOS_FAT12 is now replaced by FAT12_THRESHOLD to make it
consistent with the definition in mkdosfs and to remove the dependency
on the kernel version.
