f5696a4a7e For read/write don't update sft_posit in dosfns.c anymore so fatfs.c takes
care of it.

76c967d581 Remove usage of the fnode f_flags field where it is not relevant anymore.
Because of the explicit dir_write() calls we only need them in situations
where SFTs where used, that is for open files but not for directories.

f57099220b Introduce clear_dir() to clear a directory, this was code shared between
dos_mkdir() and extend_dir(). Now dos_mkdir() calls this function to clear
the new directory, and then creates the . and .. entries using higher level
functions instead of dealing with the blocks directly.

fedf951beb Eliminate the fnode F_DDIR flag which has no SFT equivalent:
f_sft_idx==0xff can do the same. rwblock() is never called for directories
so the checks could be removed.

4a6e5677ad Change dos_rmdir to only use 1 fnode. It now first checks if the directory
is empty and then opens the parent and deletes the real directory.

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.

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.
