Overhaul URI types, parsers, 'uri!' macro. 

This commit entirely rewrites Rocket's URI parsing routines and
overhauls the 'uri!' macro resolving all known issues and removing any
potential limitations for compile-time URI creation. This commit:

  * Introduces a new 'Reference' URI variant for URI-references.
  * Modifies 'Redirect' to accept 'TryFrom<Reference>'.
  * Introduces a new 'Asterisk' URI variant for parity.
  * Allows creation of any URI type from a string literal via 'uri!'.
  * Enables dynamic/static prefixing/suffixing of route URIs in 'uri!'.
  * Unifies 'Segments' and 'QuerySegments' into one generic 'Segments'.
  * Consolidates URI formatting types/traits into a 'uri::fmt' module.
  * Makes APIs more symmetric across URI types.

It also includes the following less-relevant changes:

  * Implements 'FromParam' for a single-segment 'PathBuf'.
  * Adds 'FileName::is_safe()'.
  * No longer reparses upstream request URIs.

Resolves #842.
Resolves #853.
Resolves #998.

/// Type-safe, URI-safe generation of an [`Origin`] URI from a route.
/// Type-safe, encoding-safe route and non-route URI generation.
///
/// The `uri!` macro creates a type-safe, URL-safe URI given a route and values
/// for the route's URI parameters. The inputs to the macro are the path to a
/// route, a colon, and one argument for each dynamic parameter (parameters in
/// `<>`) in the route's path and query.
/// The `uri!` macro creates type-safe, URL-safe URIs given a route and concrete
/// parameters for its URI or a URI string literal.
///
/// For example, for the following route:
/// # String Literal Parsing
///
/// ```rust
/// # #[macro_use] extern crate rocket;
/// #
/// #[get("/person/<name>?<age>")]
/// fn person(name: String, age: Option<u8>) -> String {
/// # "".into() /*
/// ...
/// # */
/// }
/// Given a string literal as input, `uri!` parses the string using
/// [`Uri::parse_any()`] and emits a `'static`, `const` value whose type is one
/// of [`Asterisk`], [`Origin`], [`Authority`], [`Absolute`], or [`Reference`],
/// reflecting the parsed value. If the type allows normalization, the value is
/// normalized before being emitted. Parse errors are caught and emitted at
/// compile-time.
///
/// The grammar for this variant of `uri!` is:
///
/// ```text
/// uri := STRING
///
/// STRING := an uncooked string literal, as defined by Rust (example: `"/hi"`)
/// ```
///
/// A URI can be created as follows:
/// `STRING` is expected to be an undecoded URI of any variant.
///
/// ## Examples
///
/// ```rust
/// # #[macro_use] extern crate rocket;
/// use rocket::http::uri::Absolute;
///
/// // Values returned from `uri!` are `const` and `'static`.
/// const ROOT_CONST: Absolute<'static> = uri!("https://rocket.rs");
/// static ROOT_STATIC: Absolute<'static> = uri!("https://rocket.rs?root");
///
/// // Any variant can be parsed, but beware of ambiguities.
/// let asterisk = uri!("*");
/// let origin = uri!("/foo/bar/baz");
/// let authority = uri!("rocket.rs:443");
/// let absolute = uri!("https://rocket.rs:443");
/// let reference = uri!("foo?bar#baz");
///
/// # use rocket::http::uri::{Asterisk, Origin, Authority, Reference};
/// # // Ensure we get the types we expect.
/// # let asterisk: Asterisk = asterisk;
/// # let origin: Origin<'static> = origin;
/// # let authority: Authority<'static> = authority;
/// # let absolute: Absolute<'static> = absolute;
/// # let reference: Reference<'static> = reference;
/// ```
///
/// # Type-Safe Route URIs
///
/// A URI to a route name `foo` is generated using `uri!(foo(v1, v2, v3))` or
/// `uri!(foo(a = v1, b = v2, c = v3))`, where `v1`, `v2`, `v3` are the values
/// to fill in for route parameters named `a`, `b`, and `c`. If the named

/// order.

///
/// ## Semantics
/// ## Dynamic Semantics
///
/// The `uri!` macro returns an [`Origin`] structure with the URI of the
/// supplied route interpolated with the given values. Note that `Origin`
/// implements `Into<Uri>` (and by extension, `TryInto<Uri>`), so it can be
/// converted into a [`Uri`] using `.into()` as needed.
/// The returned value is that of the prefix (minus any query part) concatenated
/// with the route URI concatenated with the query (if the route has no query
/// part) and fragment parts of the suffix. The route URI is generated by
/// interpolating the declared route URI with the URL-safe version of the route
/// values in `uri!()`. The generated URI is guaranteed to be URI-safe.
///
/// A `uri!` invocation only typechecks if the type of every value in the
/// invocation matches the type declared for the parameter in the given route,
/// after conversion with [`FromUriParam`], or if a value is ignored using `_`
/// and the corresponding route type implements [`Ignorable`].
/// Each route value is rendered in its appropriate place in the URI using the
/// [`UriDisplay`] implementation for the value's type. The `UriDisplay`
/// implementation ensures that the rendered value is URL-safe.
///
/// Each value passed into `uri!` is rendered in its appropriate place in the
/// URI using the [`UriDisplay`] implementation for the value's type. The
/// `UriDisplay` implementation ensures that the rendered value is URI-safe.
/// A `uri!()` invocation allocated at-most once.
///
/// If a mount-point is provided, the mount-point is prepended to the route's
/// URI.
/// ## Static Semantics
///
/// The `uri!` macro returns one of [`Origin`], [`Absolute`], or [`Reference`],
/// depending on the types of the prefix and suffix, if any. The table below
/// specifies all combinations:
///
/// | Prefix | Suffix | Output |
/// |------------|-------------|-------------|
/// | None | None | `Origin` |
/// | None | `Absolute` | `Origin` |
/// | None | `Reference` | `Reference` |
/// | `Origin` | None | `Origin` |
/// | `Origin` | `Absolute` | `Origin` |
/// | `Origin` | `Reference` | `Reference` |
/// | `Absolute` | None | `Absolute` |
/// | `Absolute` | `Absolute` | `Absolute` |
/// | `Absolute` | `Reference` | `Reference` |

/// A `uri!` invocation only typechecks if the type of every route URI value in
/// the invocation matches the type declared for the parameter in the given
/// route, after conversion with [`FromUriParam`], or if a value is ignored
/// using `_` and the corresponding route type implements [`Ignorable`].
///
/// ### Conversion
///
/// The [`FromUriParam`] trait is used to typecheck and perform a conversion for
/// each value passed to `uri!`. If a `FromUriParam<P, S>` implementation exists
/// for a type `T` for part URI part `P`, then a value of type `S` can be used
/// in `uri!` macro for a route URI parameter declared with a type of `T` in
/// part `P`. For example, the following implementation, provided by Rocket,
/// each value passed to `uri!`. If a `FromUriParam<P, S> for T` implementation
/// exists for a type `T` for part URI part `P`, then a value of type `S` can be
/// used in `uri!` macro for a route URI parameter declared with a type of `T`
/// in part `P`. For example, the following implementation, provided by Rocket,
/// allows an `&str` to be used in a `uri!` invocation for route URI parameters
/// declared as `String`:
///
/// ```rust,ignore
/// impl<P: UriPart, 'a> FromUriParam<P, &'a str> for String { .. }
/// impl<P: Part, 'a> FromUriParam<P, &'a str> for String { .. }

The [`Part`] trait categorizes types that mark a part of the URI as either a
[`Path`] or a [`Query`]. Said another way, types that implement `Part` are
marker types that represent a part of a URI at the type-level. Traits such as
[`UriDisplay`] and [`FromUriParam`] bound a generic parameter by `UriPart`: `P:
UriPart`. This creates two instances of each trait: `UriDisplay<Query>` and
