Daniel Rocco 3c126bad72 test: implement parenthesized expressions, additional tests
- Replace the parser with a recursive descent implementation that handles
  parentheses and produces a stack of operations in postfix order.

  Parsing now operates directly on OsStrings passed by the uucore framework.

- Replace the dispatch mechanism with a stack machine operating on the
  symbol stack produced by the parser.

- Add tests for parenthesized expressions.

- Begin testing character encoding handling.
