07d2b24149 Make findfirst/findnext more MSDOS compatible: 
* ignore 0x40 (D_DEVICE) in search attribute.
* if you specify D_VOLID + one or more of D_HIDDEN, D_SYSTEM, and D_DIR you
  will get files *and* volume labels in the specified directory, not forced
  to the root directory.
* VOLID searches must look at the search pattern name too, or do not match.

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.

054631c300 Ported COUNTRY.SYS support from the unstable branch.

if it does not exist, not complain and load the built-in info.

d519f3db40 This change was missed, as the changelog mentioned it was in 2035a already: 
r_si/r_di contents added as documented in PC-DOS Technical Update.
I also moved the CharReqHdr filling in to just before execrh, and
made the command table a static const so it is outside the SDA (OW places
it in CONST2).

b8cabddd8e r1115 set the dpb_subunit but that was wrong for get_cds() called from AX=4409. 
Use a local variable unit to avoid that, and simplify the AX=4409 logic like
in the unstable kernel.

17bd0113b2 Split DosDevIoctl into two calls so execrh can be called with minimal 
stack usage. Always return DE_ACCESS when the device fails instead
of DE_DEVICE, as DE_DEVICE is only used for renames between devices that
are not the same.

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.

f_sft_idx==0xff can do the same. rwblock() is never called for directories
so the checks could be removed.

a0382d32e4 Eliminate dos_setfsize, dos_setftime, and dos_lseek, by just using the SFT.

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 :-).
