d94c5aba12 Fix Readdirnames to behave properly if reading in little pieces. Requires storing some 
state in the FD.

This is Darwin only.  Next CL will make Readdir use Readdirnames to generate its files
and move Readdir into portable code, as well as fix Readdirnames for Linux.

187cf78a7c - preparation for setting up types 
- 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)

fc8dca9dac heuristic to stop pulling .6 in from .a 
is not right if the .6 is only for data and
the init function.

instead of that, pick up everything and
let the dead code/data eliminator throw
away the parts that weren't useful.
