split off thread specific stuff from struct sigacts to struct sigctx, leaving

move other random signal stuff from struct proc to struct sigctx

Some small optimisations:
...
o Avoid checking cputype when the kernel is built for one cpu variant only.
o In writeback(), don't use bcopy() to write a mere 16 bytes of 16-byte
aligned data; it's much quicker to copy it inline.

A small splx()/spl0()/soft interrupt related optimisation. If we're

dropping to spl0, use inline code to check if a soft interrupt is
