  Modified files:
    sys/dev/ubsec        ubsec.c ubsecvar.h 
  Log:
  Redo locking for proper SMP operation:
  
  o replace driver-global lock with three locks: one for the handling of mcr1
    operations, one for handling of mcr2 operations, and one for the mcr1
    free list
  o mark the interrupt handler MPSAFE
  o don't use locking on detach; disabling interrupts is sufficient (I think)
