This patch renames a number of types and functions making
the API more consistent.
* `Server` -> `Connection`
* `Client` -> `SendRequest`
* `Respond` -> `SendResponse`.
It also moves the handshake fns off of `Connection` and make
them free fns in the module. And `Connection::builder` is removed
in favor of `Builder::new`.
The Connection type is a `Future` that drives all of the IO of the
client connection.
The Client type is separate, and is used to send requests into the
connection.
This change adds a .rustfmt.toml that includes ALL supported settings,
12 of which we have overridden to attempt to cater to our own
proclivities.
rustfmt is checked in the rust-nightly CI job.
Use a temporary private fork of tokio-rustls that uses Rustls 0.12
until tokio-rustls 0.4 is released.
This upgrades, among other things, *ring* to 0.12, which will ensure
that it still builds in the Rust 1.20 release coming this week even if
backward-compatibility-breaking changes to rustc aren't fixed before
the release.
With this change, h2 can build and run without any manual configuration steps for -msvc targets. Previously manual installation of OpenSSL libraries was required.
