cd79fe5f31 Fix 386 register save/restore (FS & GS destroyed across EXEC - SF bug: 3090610) 
Involves:
* before calling INT24 restore 386 registers. Protect again when
  re-entering DOS for "(A)bort"
* INT21/AH=4C and variations restore 386 registers from the user stack
* INT23 (ctrl-break) restores 386 registers
* INT2F/AH=14 protects 386 registers.
* EXECRH is marked to potentially modify FS/GS for OW.

a46d6637fa Use near pointers for printf()s where possible. Problematic is only the 
case where SS!=DS (which happens sometimes in resident code), in which
case va_list/va_arg need to use FAR pointers.
DS!=DGROUP never works, so I corrected that for NLS_DEBUG, by setting DS
in int2f.asm.

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 :-).
