  Modified files:
    sys/alpha/alpha      machdep.c 
    sys/alpha/include    ucontext.h 
  Log:
  Use a spare slot in the machine context to identify the context format
  and to inherently verify its validity.  Alpha signal frames and trap
  frames are different; this field identifies which format the context
  is
  
  Set the machine context format (signal frame) before copying it out
  when sending a signal.
