X-Forwarded-Port contains the destination port, not the source port,
so it isn't useful for our purposes.
Move parsing of X-Forwarded-* header fields to parseForwarded.
Prior to being registered, upstreamConn.handleMessage doesn't run
in the user goroutine, it runs in a goroutine specific to the
network. Thus we shouldn't access any user data structure from
there.
downstreamConn.updateSupportedCaps is already called from the
eventUpstreamConnected handler in user.run, the call being removed
was unnecessary.

The methods didn't have pointer receivers. Thus the deadline fields
were only updated for the local variable.

... and do not forward INVITEs to downstreams that do not support the
capability.
The downstream capability can be permanent because there is no way for a
client to get the list of people invited to a channel, thus no state can
be corrupted.
... so that the JOIN/history batch takes into account all capabilities.
Without this commit for example, enabling multi-prefix after the batch
makes the client send NAMES requests for all channels, which generate
needless traffic.
This adds the `channel update` service command, which is used to set the
auto-detach, auto-reattach, and message relaying settings of a channel.
Of note is that currently the parser parses `#` as a comment, which
means any `channel update #foo ...` will actually need to be escaped to
`channel update "#foo" ...`
This uses the fields added previously to the Channel struct to implement
the actual detaching/reattaching/relaying logic.
The `FilterDefault` values of the messages filters are currently
hardcoded.
The values of the message filters are not currently user-settable.
This introduces a new user event, eventChannelDetach, which stores an
upstreamConn (which might become invalid at the time of processing), and
a channel name, used for auto-detaching. Every time the channel detach
timer is refreshed (by receveing a message, etc.), a new timer is
created on the upstreamChannel, which will dispatch this event after the
duration (and discards the previous timer, if any).
This adds several fields to the channel database schema and struct.
These fields will be used to add support for customizable message
relaying through BouncerServ, auto-reattaching, auto-detaching.
- RelayDetached is a filter for which notices to relay through
BouncerServ for detached channels.
- ReattachOn is a filter for which messages to trigger a channel
reattach on.
- DetachAfter is the duration after which to automatically detach a
channel if no matching messages are received.
- DetachOn is a filter for which messages will reset the auto-detach
timer.
This commit prevents downstream from sending those commands:
- NICK BouncerServ
- NICK BouncerServ/<network>
The later is necessary because soju would otherwise save the nick change
and, in the event that the downstream connects in single-upstream mode
to <network>, it will end up with the nickname "BouncerServ".
This patch implements basic message delivery receipts via PING and PONG.
When a PRIVMSG or NOTICE message is sent, a PING message with a token is
also sent. The history cursor isn't immediately advanced, instead the
bouncer will wait for a PONG message before doing so.
Self-messages trigger a PING for simplicity's sake. We can't immediately
advance the history cursor in this case, because a prior message might
still have an outstanding PING.
Future work may include optimizations such as removing the need to send
a PING after a self-message, or groupping multiple PING messages
together.

TAGMSG are (in current specs and drafts from IRCv3) only used for
client tags. These are optional information by design (since they are
not distributed to all users), therefore it is preferable to discard
them accordingly to upstream, instead of waiting for all upstreams to
support the capability to advertise it.
It's too easy to setup a reverse proxy which doesn't support the PROXY
protocol, or lets the X-Forwarded-For header fields pass through.
Disable this by default.
To restore the previous behaviour, add `accept-proxy-ip localhost` to
the config file.
