* add gotype string to symbol table
* fill in gotype in 6l for known funcs/vars
* print gotype with nm -t
* load symbol and pc/ln tables into memory at magic address 0x99<<32.
* add sys.symdat() to retrieve raw bytes of symbol table
and pc/ln table.
most of this should be considered experimental
and subject to change.

* rewrite lock implementation to be correct

* 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.
