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.

<lnussel@suse.de> to fix handling of zero heads and sectors:
* the HDIO_GETGEO ioctl works on device mapper devices but returns
zero heads and sectors. Therefore let's a) assume dummy values in
that case in mkdosfs and b) don't consider such fat file systems as
invalid in dosfsck. The Linux kernel accepts them anyways.

<karlt@karlt.net> to fix dosfsck zero slot crashes:
* Fixes crashes due to zero slot numbers causing a negative offset in
the call to copy_lfn_part in lfn_add_slot. On amd64 this results in
a SIGSEGV in copy_lfn_part. On x86 the result is heap corruption and
thus sometimes a SIGSEGV or double free abort later. (Closes:
#152550, #353198, #356377, #401798).
