efc86a74e4 change meaning of $GOMAXPROCS to number of cpus to use,
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.

67addd4e11 symbol table changes
* 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.

	local type T in file x.go T_x -> T·x
	second one T_x_1 -> T·x·1

	method names M on T  T_M -> T·M

correctly handle local embedded types

5383e28ea0 change string([]byte) to pass array, rather than &a[0],
to string convert.  if the byte array has length 0,
the computation of &a[0] throws an index bounds error.

for fixed size arrays, this ends up invoking arrays2d
unnecessarily, but it works.
