  Modified files:
    sys/alpha/include    frame.h 
  Log:
  * Move exception_return to exception.s which is a more logical home for it.
  * Optimise the return path for syscalls so that they only restore a minimal
    set of registers instead of performing a full exception_return.
  
  A new flag in the trapframe indicates that the frame only holds partial
  state. When it is necessary to perform a full state restore (e.g. after an
  execve or signal), the flag is cleared to force a full restore.
