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.

896908d6f7 Eliminate DosGetFile -- it is no longer necessary because the filename
is already copied from the fnode.

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.

31bc1f6149 Added support for BUFFERSHIGH as alias to BUFFERS: No new code
but useful for people who are used to writing HIGH everywhere.
Thanks to Christian Wallbaum the hint that config.txt had both.
Removed code which called int 16.1 in a loop before 16.0 - this
would only be useful if you invoke HLT before each int 16.1 ...

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?]

0cc297cf2d The truename function must use the current working directory of
the virtual / created-by-subst drive when it resolves relative
paths, even though truename returns the "real" drive and dir
of where your files actually are in the end. Using the current
directory of the "real" drive made truename give wrong results.

PS: If "subst e: d:\" says "physical path x:\ cannot be made",
then it refers to "making" a root dir. "subst e: d:\foo" works.

f7320f6452 Init HaltCpuWhileIdle to 0 before installing int handlers.
Removed HaltCpuWhileIdle handling from GetBiosKey because it is
only used *before* IDLEHALT is processed anyway - in the config

like "switches /i" would be a way to enable it a bit earlier.

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 :-).
