move darwin-amd64 specific code into runtime/darwin/amd64/
repeat for linux.
move rt0 into runtime.a instead of keeping a separate .6 file.
6l seems to have no problem with that.

* syscall:
add syscall.RawSyscall, which doesn't use sys.entersyscall/sys.exitsyscall
add syscall.dup2
add syscall.BytePtrPtr
add syscall.Rusage, RusagePtr
add syscall.F_GETFD, F_SETFD, FD_CLOEXEC
* runtime:
clean up, correct signal handling.
can now survive (continue running after) a signal.

not number of threads. can still starve all the other threads,
but only by looping, not by waiting in a system call.
fix darwin syscall.Syscall6 bug.
fix chanclient bug.
delete $GOMAXPROCS from network tests.
add stripped down printf, sys.printhex to runtime.

- do not print tracebacks if $GOTRACEBACK=0
- set GOTRACEBACK=0 during tests
- filter out pc numbers in errors

- disassemble the instructions in a trace trap to see if it's a run-time trap
- if so, print relevant info
- avoid double-printing traceback on panic

* rewrite lock implementation to be correct
(tip: never assume that an algorithm you found
in a linux man page is correct.)
* delete unneeded void* arg from clone fn
* replace Rendez with Note
* comment mal better
* use 6c -w, fix warnings
* mark all assembly functions 7

* kick off new os procs (machs) as needed
* add sys·sleep for testing
* add Lock, Rendez
* properly lock mal, sys·newproc, scheduler
* linux syscall arg #4 is in R10, not CX
* chans are not multithread-safe yet
* multithreading disabled by default;
set $gomaxprocs=2 (or 1000) to turn it on
This should build on OS X but may not.
Rob and I will fix soon after submitting.

factor the runtime into architecture-dependent and -independent pieces.
ditto for the OS dependence.
