Sergio Benitez 61f107f550 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.

Sergio Benitez 56c6a96f6a Overhaul URI types.
This is fairly large commit with several entangled logical changes.

The primary change in this commit is to completely overhaul how URI
handling in Rocket works. Prior to this commit, the `Uri` type acted as
an origin API. Its parser was minimal and lenient, allowing URIs that
were invalid according to RFC 7230. By contrast, the new `Uri` type
brings with it a strict RFC 7230 compliant parser. The `Uri` type now
represents any kind of valid URI, not simply `Origin` types. Three new
URI types were introduced:

  * `Origin` - represents valid origin URIs
  * `Absolute` - represents valid absolute URIs
  * `Authority` - represents valid authority URIs

The `Origin` type replaces `Uri` in many cases:

  * As fields and method inputs of `Route`
  * The `&Uri` request guard is now `&Origin`
  * The `uri!` macro produces an `Origin` instead of a `Uri`

The strict nature of URI parsing cascaded into the following changes:

  * Several `Route` methods now `panic!` on invalid URIs
  * The `Rocket::mount()` method is (correctly) stricter with URIs
  * The `Redirect` constructors take a `TryInto<Uri>` type
  * Dispatching of a `LocalRequest` correctly validates URIs

Overall, URIs are now properly and uniformly handled throughout Rocket's
codebase, resulting in a more reliable and correct system.

In addition to these URI changes, the following changes are also part of
this commit:

  * The `LocalRequest::cloned_dispatch()` method was removed in favor of
    chaining `.clone().dispatch()`.
  * The entire Rocket codebase uses `crate` instead of `pub(crate)` as a
    visibility modifier.
  * Rocket uses the `crate_visibility_modifier` and `try_from` features.

A note on unsafety: this commit introduces many uses of `unsafe` in the
URI parser. All of these uses are a result of unsafely transforming byte
slices (`&[u8]` or similar) into strings (`&str`). The parser ensures
that these casts are safe, but of course, we must label their use
`unsafe`. The parser was written to be as generic and efficient as
possible and thus can parse directly from byte sources. Rocket, however,
does not make use of this fact and so would be able to remove all uses
of `unsafe` by parsing from an existing `&str`. This should be
considered in the future.

Fixes #443.
Resolves #263.
