  Modified:    i386/include  apic.h ipl.h smptests.h spl.h
  Log:
  control of new IPI_INTR() entry points.
  #define IPI_INTS in i386/include/apic.h to enable (the default).
  #define TEST_IPI in i386/include/smptests.h for test code (default for now).
  
  removed TEST_DISABLEFOCUS define from smptests.h

  Log:
  new IPI_INTR() entry points.

  This code gives us 4 InterProcessor Interrupts in the IDT table.
  Generically named Xipi2[4567],
   they link to skeleton functions mp_machdep.c:ipiIntr[0123]().
  
  These will be used to send messages between CPUs.  Eventually some will be
  tweaked to do everything in asm inside XipiN, while others will be expanded
  via the skeleton functions.
  
  Support functions in mpapic.c include:
  
  send an IPI INTerrupt containing 'vector' to CPUs in 'targetMap':
  selectedProcsIPI( int targetMap, int vector )
  
  send an IPI INTerrupt containing 'vector' to all CPUs, including myself:
  allProcsIPI( int vector )
  
  send an IPI INTerrupt containing 'vector' to all CPUs EXCEPT myself:
  allButSelfIPI( int vector )
  
  send an IPI INTerrupt containing 'vector' to myself:
  selfIPI( int vector )
