Interrupts / Start using winedos handlers

[Jukka Heinonen]

This patch makes Wine use interrupt handlers declared in winedos for all
RM and PM interrupts. Now, what is left is copying interrupt handler code 
from msdos/* to dlls/winedos/* and removing duplicated stuff from msdos.

Files int12.c, int13.c, int1a.c, int2a.c, fpu.c, int41.c and int4b.c
could be directly copied to dlls/winedos if functions matching pattern
INT_Int??Handler are renamed to DOSVM_Int??Handler and the corresponsing 
functions are removed from dlls/winedos/interrupts.c. Files int2f.c and int15.c 
require only minor changes. Other interrupt handlers (dpmi.c, int11.c, int21.c, 
int25.c, int 26.c and int5c.c) require more work and some of them probably 
should be left to msdos.


Changelog:
  Start using winedos handlers for all interrupts.
