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.

0760d51339 If handle valid, close file in PSP table before the low-level close + 
(perhaps) critical error.
Avoids closing the file twice (and hitting the critical error twice) on
abort/program termination.
Also, close can only return error 6 (DE_INVLDHNDL), not 5 (DE_ACCESS), see RBIL.

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.
