Sergio Benitez fd294049c7 Update to hyper 1. Enable custom + unix listeners.
This commit completely rewrites Rocket's HTTP serving. In addition to
significant internal cleanup, this commit introduces the following major
features:

  * Support for custom, external listeners in the `listener` module.

    The new `listener` module contains new `Bindable`, `Listener`, and
    `Connection` traits which enable composable, external
    implementations of connection listeners. Rocket can launch on any
    `Listener`, or anything that can be used to create a listener
    (`Bindable`), via a new `launch_on()` method.

  * Support for Unix domain socket listeners out of the box.

    The default listener backwards compatibly supports listening on Unix
    domain sockets. To do so, configure an `address` of
    `unix:path/to/socket` and optional set `reuse` to `true` (the
    default) or `false` which controls whether Rocket will handle
    creating and deleting the unix domain socket.

In addition to these new features, this commit makes the following major
improvements:

  * Rocket now depends on hyper 1.

  * Rocket no longer depends on hyper to handle connections. This allows
    us to handle more connection failure conditions which results in an
    overall more robust server with fewer dependencies.

  * Logic to work around hyper's inability to reference incoming request
    data in the response results in a 15% performance improvement.

  * `Client`s can be marked secure with `Client::{un}tracked_secure()`,
    allowing Rocket to treat local connections as running under TLS.

  * The `macros` feature of `tokio` is no longer used by Rocket itself.
    Dependencies can take advantage of this reduction in compile-time
    cost by disabling the new default feature `tokio-macros`.

  * A new `TlsConfig::validate()` method allows checking a TLS config.

  * New `TlsConfig::{certs,key}_reader()`,
    `MtlsConfig::ca_certs_reader()` methods return `BufReader`s, which
    allow reading the configured certs and key directly.

  * A new `NamedFile::open_with()` constructor allows specifying
    `OpenOptions`.

These improvements resulted in the following breaking changes:

  * The MSRV is now 1.74.
  * `hyper` is no longer exported from `rocket::http`.
  * `IoHandler::io` takes `Box<Self>` instead of `Pin<Box<Self>>`.
    - Use `Box::into_pin(self)` to recover the previous type.
  * `Response::upgrade()` now returns an `&mut dyn IoHandler`, not
    `Pin<& mut _>`.
  * `Config::{address,port,tls,mtls}` methods have been removed.
    - Use methods on `Rocket::endpoint()` instead.
  * `TlsConfig` was moved to `tls::TlsConfig`.
  * `MutualTls` was renamed and moved to `mtls::MtlsConfig`.
  * `ErrorKind::TlsBind` was removed.
  * The second field of `ErrorKind::Shutdown` was removed.
  * `{Local}Request::{set_}remote()` methods take/return an `Endpoint`.
  * `Client::new()` was removed; it was previously deprecated.

Internally, the following major changes were made:

  * A new `async_bound` attribute macro was introduced to allow setting
    bounds on futures returned by `async fn`s in traits while
    maintaining good docs.

  * All utility functionality was moved to a new `util` module.

Sergio Benitez 847e87d5c9 Make 'ws::Stream![]' mean 'ws::Stream!['static]'.
This is in line with the stream macros in Rocket core.

Sergio Benitez 1d2cc257dc Preprocess tungstenite 'ConnectionClosed' errors.
Tungstenite abuses `Err(ConnectionClosed)` to indicate the non-error
condition of a websocket closing. This commit changes error processing
such that the error is caught and converted into a successful
termination of websocket handling.
