* keep coherent SP/PC in gobuf
(i.e., SP that would be in use at that PC)
* gogocall replaces setspgoto,
should work better in presence of link registers
* delete unused system calls
only amd64; 386 is now broken

* heuristic to go farther during stack traces.
* significantly improved Linux thread handing.
acid:
* update to new libmach interface.
prof:
* use new libmach interface.
* multiple thread support (derived from Rob's copy).
* first steps toward pprof-like graphs:
keep counters indexed by pc,callerpc pairs.

these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.
(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)
the longs were rare enough that i don't think
it will cause integration problems.
