54ec719391 fix string range to have full unicode range (up to 10FFFF). 
add test for string range.

test has minor failure: after loop the index == len(s); should be len(s)-1
in this case.  according to spec, vars are left at position at last
iteration.

95100344d3 fix runtime stack overflow bug that gri ran into: 
160 - 75 was just barely not enough for deferproc + morestack.

added enum names and bumped to 256 - 128.
added explanation.

changed a few mal() (garbage-collected) to
malloc()/free() (manually collected).

9f726c2c8b Use explicit allspan list instead of 
trying to find all the places where
spans might be recorded.

Free can cascade into complicated
span manipulations that move them
from list to list; the old code had the
possibility of accidentally processing
a span twice or jumping to a different
list, causing an infinite loop.

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.
