aab06b8a4d Do not use FSINFO structure if it is not present. 
Do some range checks on FSINFO values to make sure they are valid. Fixes
issue reported by dos386 on the mailing list.

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.
