Also correct various Socks related types. This commit also
adds a new gun:protocols/0 type as a simpler way of describing
preferred protocols. The protocol/opts tuple is also documented.
This commit also fixes an issue with the default value for the
preferred protocols when using CONNECT over TLS. It was
mistakenly not enabling http2 by default.

The graceful shutdown is implemented through a new 'closing'
state. This state is entered under different circumstances
depending on the protocol.
The gun:shutdown/1 function is now implemented and documented.
It allows shutting down the connection gracefully regardless
of the current state of the connection and for all protocols.
The behavior is entirely dependent on the protocol.
For HTTP/1.1 the connection stays up only until after the
current stream is complete; other streams are immediately
canceled.
For HTTP/2 a GOAWAY frame is sent and existing streams
continue to be processed. The connection is closed after
all streams are processed and the server's GOAWAY frame
is received.
For Websocket a close frame is sent. The connection is
closed when receiving the server's close frame.
In all cases the closing_timeout option defines how long
we wait, as a maximum, before closing the connection after
the graceful shutdown was started.
The graceful shutdown is also initiated when the owner
process goes away; when sending an HTTP/1.1 request
with the connection: close header; when receiving an
HTTP/1.1 response with the connection: close header;
when receiving an HTTP/1.0 response without a connection
header; when the server sends a GOAWAY HTTP/2 frame;
or when we send or receive a Websocket close frame.
Along with these changes, the gun:ws_send/2 function
now accepts a list of frames as argument. Those frames
may include a close frame that initiates the graceful
shutdown.

Flow control is disabled by default. The initial flow value
must be set to enable it (either for the entire connection
or on a per-request basis). Flow applies to all HTTP streams
as well as Websocket. HTTP/2 pushed streams receive the same
value as their originating stream.

This changes the way we connect to servers entirely. We now have
three states when connecting (domain_lookup, connect and
tls_handshake when applicable) and as a result three corresponding
timeout options. Each state has a start/end event associated and
the event data was tweaked to best match each event. Since the
TLS handshake is separate, the transport_opts option was also
split into two: tcp_opts and tls_opts.

Header names can now be provided as binary, string or atom
and Gun no longer requires them to be in lowercase. The list
of headers can also be provided as a map as well.

Also fix an http into http2 for one option.

In particular the switch to gen_statem broke things with
Erlang/OTP before 19.3.
|
|
This is safer as servers may reject too many extra empty lines.
|
|
This cleaner separation gets rid of the implicit body check
that was causing issues for many users. Now the body is
either given explicitly or it is expected via future
gun:data/3 calls.

This fixes HTTP/2 over TLS connections.
The protocol destination option has been deprecated in favor
of a protocols option.

We instead of two new modules, gun_tcp and gun_tls.
They only have 6 functions so far, much less than
what Ranch provided before.
Also renames ssl to tls where applicable. It's still
possible to use the ssl transport option but it's now
undocumented.

This disables the keepalive mechanism entirely.

I just replaced "SPDY" with "HTTP/2" in the documentation.
I suspect that's all that's needed, but if there's something
off we can fix it later.
