Sergio Benitez d7f6d82fe4 Implement 'FromForm[Value]', 'Responder' proc-macro derives.
This completes the migration of custom derives to proc-macros, removing
the need for the `custom_derive` feature in consumer code. This commit
also includes documentation, unit tests, and compile UI tests for each
of the derives.

Additionally, this commit improves the existing `FromForm` and
`FromFormValue` derives. The generated code for `FromForm` now returns
an error value indicating the error condition. The `FromFormValue`
derive now accepts a `form` attribute on variants for specifying the
exact value string to match against.

Closes #590.
Closes #670.

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.

Sergio Benitez f171dc9d09 Reorganize repository.
The directory structure has changed to better isolate crates serving
core and contrib. The new directory structure is:

  contrib/
    lib/ - the contrib library
  core/
    lib/ - the core Rocket library
    codegen/ - the "compile extension" codegen library
    codegen_next/ - the new proc-macro library
  examples/ - unchanged
  scripts/ - unchanged
  site/ - unchanged

This commit also removes the following files:

  appveyor.yml - AppVeyor (Rust on Windows) is far too spotty for use
  rustfmt.toml - rustfmt is, unfortunately, not mature enough for use

Finally, all example Cargo crates were marked with 'publish = false'.
