* move memmove to arch-specific subdirectories
* add memmove for arm
* add copyright notices marking them as copied from Inferno

cgo/libmach remain unimplemented. However, compilers, runtime,
and packages are 100%. I still need to go through and implement
missing syscalls (at least make sure they're all listed), but
for all shipped functionality, this is done. Ship! ;)

because they are in package runtime.
another step to enforcing package boundaries.

* in 6l, -K already meant check for stack underflow.
add -KK to mean double-check stack overflows
even in nosplit functions.
* comment out print locks; they deadlock too easily
but are still useful to put back for special occasions.
* let runcgo assembly switch to scheduler stack
without involving scheduler directly. because runcgo
gets called from matchmg, it is too hard to keep it
from being called on other stacks.

better mach binaries.
cgo working on darwin+linux amd64+386.
eliminated context switches - pi is 30x faster.
add libcgo to build.
on snow leopard:
- non-cgo binaries work; all tests pass.
- cgo binaries work on amd64 but not 386.

so that == on func means that the
functions originated in the same
execution of a func literal or definition.
before, there was an inconsistency:
func() {x++} != func() {x++}
but
func() {} == func() {}
this CL makes the second case != too,
just like
make(map[int]int) != make(map[int]int)

saving of sp was too far away from use in scanstack;
the stack had changed since the sp was saved.

* 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
