8751d0554c - Explicitly name the fields in pcb that we use to store trap state for later 
retrieval, rather than using pad
- save the fault address in sfar for use by the alignment fixup handler
- mask off the trap number, so the context id doesn't confuse the UT_MAX
  comparison

This change fixes alignment fixup handling which is needed for traceroute
to work in spite of its copious unaligned accesses

b3592a5ffb We no longer need to remap hardware trap numbers to sparc64 trap numbers 
as this happens much earlier in trap handling.

The fact that we continued to do this when it was no longer necessary caused
breapoint to map to SIGILL as opposed to SIGTRAP :-(.

5cd3e3457f Make sure we do not sleep while locks are held. Change the malloc(9) 
flags from M_WAITOK to M_NOWAIT. This should not cause any problems
since the calling code appears to properly handle failed allocations.

185877cc43 In contrast to the non-obvious and flexible nature of the optimized bcopy in t1_copy.S (which 
shall retain its CDDL copyright, and thus likely be removed from GENERIC) I have removed the CDDL
from hcall.S because there is zero flexibility in the implementation of hypercalls as they derive
directly from the hypervisor interface which is not copyrighted (ironically the source for the
hypervisor itself is BSD licensed).

It is best to start any bikeshed about this as soon as possible.
