Flesh out VHDL parser engine. Add enough rules to parse a simple VHDL program: Parse library and use clauses, Parse entity declarations, and Parse architecture bodies. Add some parser infrastructure: Handle syntax errors with useful error messages, Include file name and line numbers in parse errors, Add some parser debug aids.
