Russ Cox 736903c170 libmach:
* heuristic to go farther during stack traces.
	* significantly improved Linux thread handing.

acid:
	* update to new libmach interface.

prof:
	* use new libmach interface.
	* multiple thread support (derived from Rob's copy).
	* first steps toward pprof-like graphs:
	  keep counters indexed by pc,callerpc pairs.

Russ Cox fb88a01cc2 marginally better thread debugging on Linux.
if you clone inside a traced pid, the child
is automatically attached and stopped,
apparently.

Russ Cox 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.

Russ Cox 34514bdb72 Use a single Make.conf for setting CC, etc.
This makes it easy to build with other flags
(like -ggdb) or other compilers (like cc64).

Russ Cox 9aad9fef76 make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc.
these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.

(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)

the longs were rare enough that i don't think
it will cause integration problems.

type a centered dot when debugging.
