3a16a4c755 Eliminate fcbname[] on the stack: we can use dm_name_pat in the dirmatch 
structures instead.

a21bcd8a85 Split 8.3 FCB-style filename extraction from ParseDosName into a new 
ConvertNameSZToName83 function, also used by dir_open().

match structure with fields dm_entry and dm_dircluster.

ec30074f48 Make the fnode f_flags completely equal to the SFT sft_flags. 
Rename SFT_FDIRTY to SFT_FCLEAN to avoid confusion.

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.

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().

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.

7083b0a4fa On close or commit, only update those directory entry fields that have an

ba75006b67 Use explicit dir_write() instead of letting dir_close() do the writing. 
This is to prepare for an updating version to deal with SFTs.

d39420dc11 Add f_dirsector (sector containing dentry) and f_diridx (index within 
sector) fields to the fnode, to make fnodes more compatible with SFTs.
Use them to simplify dir_read() and dir_write().

2092745236 Force near fnode use to use either fnode[0] or fnode[1] instead of the 
allocation scheme. This eliminates the checks done in inthndlr.c because
the f_count field is no longer checked.

the kernel should not return a volume label in that case.

ecfcb9be29 dir_read() no longer updates the diroff counter. This eliminates the NEW 
field, simplifies remove_lfn_entries(), and avoids a bug if you delete
the first entry in the root directory on FAT32.

5d712fc2a6 Avoid bitfields for fnodes, using flags instead.

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.

c73ee8084a Remove the 65535 check for root directories. It's checked against 
a different limit later anyway later, and it breaks remove_lfn_entries...

11a7b69e5c Make f_diroff an entry offset so it can be 16bits. Enforce the 65536 
entry limit in dir_read(). Saves 80 bytes or so + 2 bytes in every f_node.

0e0abcd685 Added explicit (UWORD) type casts to avoid compiler warnings and sometimes 
save a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of bytes to
be added to SI.

5567aba08b Fixed bug #1722: dir_close() was called for normal files (via map_cluster 
and find_fat_free). This completely messed up rwblock. Removed these calls
(for directories they are already covered at a higher level) and added
a few sanity checks to dir_close and dir_write.

4f1a117069 * FAT32 kernels should ignore the upper word of the cluster number for 
FAT16 partitions (just like FAT16 kernels do)
* added extra checks to make sure that invalid FAT entries are never
  followed
* made put_console() public to be able to print a message in case of
  FAT corruption
* some small optimizations and header cleanups (some suggested by Arkady)
