  Modified files:
    sys/sparc64/sparc64  machdep.c trap.c 
  - s,tramoline,trampoline, in a comment.
  - Use FBSDID in trap.c
  - Make the global trap_sig[] static as it's not used outside of trap.c.
  - In sendsig() remove an unused variable.
  - In trap() sync with the other archs; for fast data access MMU miss and
    data access protection traps set ksi_addr to the SFAR reg which contains
    the faulting address and otherwise to the TPC reg. Generally the TCP reg
    contains the address of the instruction that caused the exception, except
    for fast instruction access traps (and some others; more refinement may
    be needed here) it also contains the faulting address.
    Previously sendsig() always set si_addr to the SFAR reg which is wrong
    for most traps.
  - In sendsig() add support for FreeBSD old-style signals.
  These changes are inspired by kmacy's sun4v changes and allow libsigsegv
  to build on FreeBSD/sparc64, but it doesn't pass all checks and tests it
  actually should, yet.
