- Add idempotency guards so the structures can be used in other utilities.
- Update bpb structs with reserved fields.
- In direntry struct join deName with deExtension. Although a
fix was attempted in the past, these fields were being overflowed,
Now this is consistent with the spec, and we can now share the
WinChksum code with NetBSD.

Remove checks for BOOTSIG[23] from FAT32 bootblocks.

There seems to be very little documentary evidence outside this
implementation to suggest a these checks are neccessary, and more
than one camera-formatted flash disk fails the check, but mounts
successfully on most other systems.

Forced commit to note that my previous commit was a Darwin merge.

Spell the BPB member of the 7.10 bootsector as bsBPB rather than bsPBP to
be like all the other bootsectors. Apple has done the same it seems.

Axe more unused GEMDOS code that was #ifdef atari.

Fix typo: seperate -> separate.

Seperate does not exist in the english language.

$Id$ -> $FreeBSD$

Update MSDOSFS code using NetBSD's msdosfs as a guide to support
FAT32 partitions. Unfortunately, we looked around here at
Walnut Creek CDROM for any newer FAT32-supporting versions
of Win95 and we were unsuccessful; only the older stuff here.
So this is untested beyond simply making sure it compiles and
someone with access to an actual FAT32 fs will have
to let us know how well it actually works.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
