5b46738372 Eliminate dir_close(). 
Its only purpose left was to flush buffers, which isn't necessary after
just open/read, so we can move that to dir_write().

7b89e44274 Make merge_file_changes more direct dealing with SFTs and merge the 
"close open files setfattr wants to change" functionality there.

a0382d32e4 Eliminate dos_setfsize, dos_setftime, and dos_lseek, by just using the SFT. 
dos_setfsize still needed to merge changes for SHARE so the call was replaced
by a new dos_merge_file_changes() call.

2092745236 Force near fnode use to use either fnode[0] or fnode[1] instead of the

26f116a217 More secure FAT handling: Avoids risk of cross links for example if 
you reboot while files are open... Reported by Hardi Stengelin :-).

Always test *link_fat* result. New function is_free_cluster.  Extra
checks in *link_fat* (bad r/w offset, i/o, write) and *next_cluster*
(dangling chain: bad value in chain) with short messages (no msg for
bad chain start). Shorter "Bad DPB" (FAT size) msg.  More comments!

Update FS INFO on disk only when needed.  Check if chain EOF was at
expected place when extending.  Call *link_fat* before! *setdstart*
when a FAT chain grows.   [Q: Does 0 byte write always trunc? Why?]

f63eea565a Made the main fnodes far so they can be in UMBs. 
Internally the kernel uses two near fnodes though, to save on codesize
and fmemcpy's if necessary. Having memory management on two fnodes is
a little silly but I just want to make sure with the panic message
that we never accidentally try to use three near fnodes at the same time.
(two are used at the same time by rename, commit, and merge_file_changes).
This can be cleaned up later.

Anyway. 644736 bytes free conv memory isn't bad.

05cd65a193 Merge find_fat_free() and extend() -- they were almost identical. 
Have a simplified clause for f_cluster == FREE.
Set f_cluster = FREE in shrink_file if the file is set to 0 bytes; in
that case we should set the current cluster to FREE even if it is
currently a LONG_LAST_CLUSTER.

ce290a033f Eliminate f_back field. 
extend() now uses f_cluster instead of f_back, while map_cluster makes
sure it's not set to LONG_LAST_CLUSTER (but to the cluster before it)
when calling extend().
extend() and first_fat() now return the new cluster number or
LONG_LAST_CLUSTER, just like find_fat_free()
Hopefully I didn't break anything... Initial testing was successful.

a few sanity checks to dir_close and dir_write.
