  - moved Object, Type, Scope  out of AST into symboltable
  - moved universe into symboltable
  - removed dead code
- fixed dependency computation (pretty -d filename.go)
- lots of cleanups
- removed tocken channel connection between parser and scanner
  (was cute, but not really needed)

	* 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.
