76f1c10a4e Eliminate xlt_fd(), save_far_f_node(), and the redundant fnode f_mode field.

c179284147 Remove redundant checks for fnodes==0 since the checks are done in dosfns.c. 
Replace global f_nodes[] array by f_sft_idx fields in the fnodes.

d7d201a53b This is the main change to eliminate far fnodes. 
SFT info is copied from and to the two near fnodes.
Some cleanups still follow.

d39420dc11 Add f_dirsector (sector containing dentry) and f_diridx (index within

bec1b777f4 New version: fdkernel.lsm, version.h to 2038 / Mar 9 2008 
(newest source file is 2008-03-09, initclk.c revision 1359)
Changelog file history.txt: added 2038pre and 2038 sections,       
with a lot of "SVN log summarizing" help from Geraldo :-)

ab53a50c49 Mktemp (21.5a) only inserts leading backslash in temp file name 
if no directory given in template if DOS version is 5.
Older and newer DOS versions just use no dirspec in that case.
This helps ftp.sac.sk/pub/sac/pack/iup067.zip exepacker which
tries to rename the temp file to a file in current directory.

Prepared Truename (21.60) to return 0 if okay, 3a00 if char dev
(and not JOIN / network?). May need further coding to actually
have the intended effect...? Note: The shell TRUENAME command
may change names for display!

Changed the "true DOS version" for FAT16 kernels from 5.0 to
6.22 to reflect the updates in 21.5a and 21.60, other 5 / 6
differences are not simply in the kernel but more in COUNTRY,
KEYB, HIMEM, SMARTDRV, DBLSPACE, EMM386, COMMAND and so on.
In addition, 6.22 is a popular version number to report :-).

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.

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.
