UTF-8 routes. Forms revamp. Temp files. Capped.

So. Many. Changes.

This is an insane commit: simultaneously one of the best (because of all
the wonderful improvements!) and one of the worst (because it is just
massive) in the project's history.

Routing:
  * All UTF-8 characters are accepted everywhere in route paths. (#998)
  * `path` is now `uri` in `route` attribute: `#[route(GET, path = "..")]`
    becomes `#[route(GET, uri = "..")]`.

Forms Revamp
  * All form related types now reside in a new `form` module.
  * Multipart forms are supported. (resolves #106)
  * Collections are supported in forms and queries. (resolves #205)
  * Nested structures in forms and queries are supported. (resolves #313)
  * Form fields can be ad-hoc validated with `#[field(validate = expr)]`.
  * `FromFormValue` is now `FromFormField`, blanket implements `FromForm`.
  * Form field values are always percent-decoded apriori.

Temporary Files
  * A new `TempFile` data and form guard allows streaming data directly to a
    file which can then be persisted.
  * A new `temp_dir` config parameter specifies where to store `TempFile`.
  * The limits `file` and `file/$ext`, where `$ext` is the file extension,
    determines the data limit for a `TempFile`.

Capped
  * A new `Capped` type is used to indicate when data has been truncated due to
    incoming data limits. It allows checking whether data is complete or
    truncated.
  * `DataStream` methods return `Capped` types.
  * `DataStream` API has been revamped to account for `Capped` types.
  * Several `Capped<T>` types implement `FromData`, `FromForm`.
  * HTTP 413 (Payload Too Large) errors are now returned when data limits are
    exceeded. (resolves #972)

Hierarchical Limits
  * Data limits are now hierarchical, delimited with `/`. A limit of `a/b/c`
    falls back to `a/b` then `a`.

Core
  * `&RawStr` no longer implements `FromParam`.
  * `&str` implements `FromParam`, `FromData`, `FromForm`.
  * `FromTransformedData` was removed.
  * `FromData` gained a lifetime for use with request-local data.
  * The default error HTML is more compact.
  * `&Config` is a request guard.
  * The `DataStream` interface was entirely revamped.
  * `State` is only exported via `rocket::State`.
  * A `request::local_cache!()` macro was added for storing values in
    request-local cache without consideration for type uniqueness by using a
    locally generated anonymous type.
  * `Request::get_param()` is now `Request::param()`.
  * `Request::get_segments()` is now `Request::segments()`, takes a range.
  * `Request::get_query_value()` is now `Request::query_value()`, can parse any
    `FromForm` including sequences.
  * `std::io::Error` implements `Responder` like `Debug<std::io::Error>`.
  * `(Status, R)` where `R: Responder` implements `Responder` by overriding the
    `Status` of `R`.
  * The name of a route is printed first during route matching.
  * `FlashMessage` now only has one lifetime generic.

HTTP
  * `RawStr` implements `serde::{Serialize, Deserialize}`.
  * `RawStr` implements _many_ more methods, in particular, those related to the
    `Pattern` API.
  * `RawStr::from_str()` is now `RawStr::new()`.
  * `RawStr::url_decode()` and `RawStr::url_decode_lossy()` only allocate as
    necessary, return `Cow`.
  * `Status` implements `Default` with `Status::Ok`.
  * `Status` implements `PartialEq`, `Eq`, `Hash`, `PartialOrd`, `Ord`.
  * Authority and origin part of `Absolute` can be modified with new
    `Absolute::{with,set}_authority()`, `Absolute::{with,set}_origin()` methods.
  * `Origin::segments()` was removed in favor of methods split into query and
    path parts and into raw and decoded versions.
  * The `Segments` iterator is smarter, returns decoded `&str` items.
  * `Segments::into_path_buf()` is now `Segments::to_path_buf()`.
  * A new `QuerySegments` is the analogous query segment iterator.
  * Once set, `expires` on private cookies is not overwritten. (resolves #1506)
  * `Origin::path()` and `Origin::query()` return `&RawStr`, not `&str`.

Codegen
  * Preserve more spans in `uri!` macro.
  * Preserve spans `FromForm` field types.
  * All dynamic parameters in a query string must typecheck as `FromForm`.
  * `FromFormValue` derive removed; `FromFormField` added.
  * The `form` `FromForm` and `FromFormField` field attribute is now named
    `field`. `#[form(field = ..)]` is now `#[field(name = ..)]`.

Contrib
  * `Json` implements `FromForm`.
  * `MsgPack` implements `FromForm`.
  * The `json!` macro is exported as `rocket_contrib::json::json!`.
  * Added clarifying docs to `StaticFiles`.

Examples
  * `form_validation` and `form_kitchen_sink` removed in favor of `forms`.
  * The `hello_world` example uses unicode in paths.
  * The `json` example only allocates as necessary.

Internal
  * Codegen uses new `exports` module with the following conventions:
    - Locals starts with `__` and are lowercased.
    - Rocket modules start with `_` and are lowercased.
    - `std` types start with `_` and are titlecased.
    - Rocket types are titlecased.
  * A `header` module was added to `http`, contains header types.
  * `SAFETY` is used as doc-string keyword for `unsafe` related comments.
  * The `Uri` parser no longer recognizes Rocket route URIs.

/// `FromTransformedData` is a data guard.
/// A data guard is a guard that operates on a request's body data. Data guards
/// validate and parse request body data via implementations of `FromData`. In
/// other words, a type is a data guard _iff_ it implements `FromData`.
///
/// Data guards are used as the target of the `data` route attribute parameter.
/// A handler can have at most one data guard.
///
/// For many data guards, implementing [`FromData`] will be simpler and
/// sufficient. All types that implement `FromData` automatically implement
/// `FromTransformedData`. Thus, when possible, prefer to implement [`FromData`]
/// instead of `FromTransformedData`.
///
/// [request guard]: crate::request::FromRequest
///
/// ## Example
///
/// In the example below, `var` is used as the argument name for the data guard
/// type `DataGuard`. When the `submit` route matches, Rocket will call the
/// `FromTransformedData` implementation for the type `T`. The handler will only be called
/// if the guard returns successfully.
/// Data guards are the target of the `data` route attribute parameter:
///

/// # #[macro_use] extern crate rocket;
/// # type DataGuard = rocket::data::Data;
/// #[post("/submit", data = "<var>")]
/// fn submit(var: DataGuard) { /* ... */ }
/// # fn main() { }
/// ```
///
/// # Transforming
///
/// Data guards can optionally _transform_ incoming data before processing it
/// via an implementation of the [`FromTransformedData::transform()`] method.
/// This is useful when a data guard requires or could benefit from a reference
/// to body data as opposed to an owned version. If a data guard has no need to
/// operate on a reference to body data, [`FromData`] should be implemented
/// instead; it is simpler to implement and less error prone. All types that
/// implement `FromData` automatically implement `FromTransformedData`.
///
/// When exercising a data guard, Rocket first calls the guard's
/// [`FromTransformedData::transform()`] method and awaits on the returned
/// future, then calls the guard's [`FromTransformedData::from_data()`] method
/// and awaits on that returned future. Rocket stores data returned by
/// [`FromTransformedData::transform()`] on the stack. If `transform` returns a
/// [`Transform::Owned`], Rocket moves the data back to the data guard in the
/// subsequent `from_data` call as a `Transform::Owned`. If instead `transform`
/// returns a [`Transform::Borrowed`] variant, Rocket calls `borrow()` on the
/// owned value, producing a borrow of the associated
/// [`FromTransformedData::Borrowed`] type and passing it as a
/// `Transform::Borrowed`.
///
/// ## Example
///
/// Consider a data guard type that wishes to hold a slice to two different
/// parts of the incoming data:
///
/// ```rust
/// struct Name<'a> {
/// first: &'a str,
/// last: &'a str
/// }
/// ```
///
/// Without the ability to transform into a borrow, implementing such a data
/// guard would be impossible. With transformation, however, we can instruct
/// Rocket to produce a borrow to a `Data` that has been transformed into a
/// `String` (an `&str`).
///
/// ```rust
/// # #[macro_use] extern crate rocket;
/// # #[derive(Debug)]
/// # struct Name<'a> { first: &'a str, last: &'a str, }
/// use std::io::{self, Read};
///

///
/// # Outcomes
///
/// The returned [`Outcome`] of a `from_data` call determines how the incoming
/// request will be processed.
///
/// * **Success**(S)
///
/// If the `Outcome` is [`Success`], then the `Success` value will be used as
/// the value for the data parameter. As long as all other parsed types
/// succeed, the request will be handled by the requesting handler.
///
/// * **Failure**(Status, E)
///
/// If the `Outcome` is [`Failure`], the request will fail with the given
/// status code and error. The designated error [`Catcher`](crate::Catcher) will be
/// used to respond to the request. Note that users can request types of
/// `Result<S, E>` and `Option<S>` to catch `Failure`s and retrieve the error
/// value.
///
/// * **Forward**(Data)
///
/// If the `Outcome` is [`Forward`], the request will be forwarded to the next
/// matching request. This requires that no data has been read from the `Data`
/// parameter. Note that users can request an `Option<S>` to catch `Forward`s.
///
/// # Provided Implementations
///
/// Rocket implements `FromTransformedData` for several built-in types. Their behavior is
/// documented here.
///
/// * **Data**
///
/// The identity implementation; simply returns [`Data`] directly.
///
/// _This implementation always returns successfully._
///
/// * **Option&lt;T>** _where_ **T: FromTransformedData**
///
/// The type `T` is derived from the incoming data using `T`'s `FromTransformedData`
/// implementation. If the derivation is a `Success`, the derived value is
/// returned in `Some`. Otherwise, a `None` is returned.
///
/// _This implementation always returns successfully._
///
/// * **Result&lt;T, T::Error>** _where_ **T: FromTransformedData**
///
/// The type `T` is derived from the incoming data using `T`'s `FromTransformedData`
/// implementation. If derivation is a `Success`, the value is returned in
/// `Ok`. If the derivation is a `Failure`, the error value is returned in
/// `Err`. If the derivation is a `Forward`, the request is forwarded.
///
/// * **String**
///
/// **Note:** _An implementation of `FromTransformedData` for `String` is only available
/// when compiling in debug mode!_
///
/// Reads the entire request body into a `String`. If reading fails, returns
/// a `Failure` with the corresponding `io::Error`.
///
/// **WARNING:** Do **not** use this implementation for anything _but_
/// debugging. This is because the implementation reads the entire body into
/// memory; since the user controls the size of the body, this is an obvious
/// vector for a denial of service attack.
///
/// * **Vec&lt;u8>**
///
/// **Note:** _An implementation of `FromTransformedData` for `Vec<u8>` is only
/// available when compiling in debug mode!_
///
/// Reads the entire request body into a `Vec<u8>`. If reading fails,
/// returns a `Failure` with the corresponding `io::Error`.
