Vinnie Falco 9d2c1e5409 Refactor grammar: ...

The Rule concept is changed:

* rules are stateful values
* nested value_type holds the result of parsing
* member function `Rule::parse` is the algorithm
* parse returns `result<value_type>`

And:

* All rfc3986 rules are reimplemented
* New grammar non-terminal elements introduced:
  - char_rule
  - not_empty_rule
  - optional_rule
  - sequence_rule
  - variant_rule
