IDL cleanup, added AST node, namespace, StageResult

Added the ability to track namespace within the tree to look for
references.  Added a BuildTree and Resolve step.  Added a 
StageResult object to return partial trees and error counts.
Built test search into parser so now test files no longer need
to be specified on the command line.

BUG=77551
TEST= python idl_parser.py --test
