Reimplement route attribute as a proc-macro. 

This commits also implement the query reform from #608. It also consists
of many, many breaking changes. Among them are:

  * Query parts in route paths use new query reform syntax.
  * Routing for queries is now lenient.
    - Default ranking has changed to reflect query reform.
  * Format routing matching has been fixed.
    - Routes with formats matching "accept" will always collide.
    - Routes with formats matching "content-type" require requests to
      have an equivalent content-type header to match.
    - Requests with imprecise content-types are treated as not having a
      content-type.
  * Generated routes and catchers respect visibility modifiers.
  * Raw getter methods from request were renamed and retooled.
    - In particular, the index parameter is based on segments in the
      route path, not dynamic parameters.
  * The method-based attributes no longer accept a keyed 'path'.
  * The 'rocket_codegen' crate is gone and will no longer be public.
  * The 'FormItems' iterator emits values of type 'FormItem'.
    - The internal form items' string can no longer be retrieved.
  * In general, routes are more strictly validated.
  * Logging from codegen now funnels through logging infrastructure.
  * Routing has been optimized by caching routing metadata.
