The first reconnection attempt waits for 1min, the second the 2min,
and so on up to 10min. There's a 1min jitter so that multiple failed
connections don't try to reconnect at the exact same time.

This is a mecanical change, which just lifts up the context.TODO()
calls from inside the DB implementations to the callers.
Future work involves properly wiring up the contexts when it makes
sense.
Typically done via:
/notice $<bouncer> <message>
Or, for a connection not bound to a specific network:
/notice $* <message>
The message is broadcast as BouncerServ, because that's the only
user that can be trusted to belong to the bouncer by users. Any
other prefix would conflict with the upstream network.
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.
Instead, always read chat history from logs. Unify the implicit chat
history (pushing history to clients) and explicit chat history
(via the CHATHISTORY command).
Instead of keeping track of ring buffer cursors for each client, use
message IDs.
If necessary, the ring buffer could be re-introduced behind a
common MessageStore interface (could be useful when on-disk logs are
disabled).

This allows to set the list of IPs allowed to act as a proxy. This is
only used for WebSockets right now, but will be expanded to TCP as well
once the PROXY protocol is supported.
This adds support for user create, a new service command only accessible
to admin users. This lets users create other users on the fly and makes
soju start the user routine immediately; unlike sojuctl which currently
requires closing soju, creating the user, and starting soju again.
WebSocket connections allow web-based clients to connect to IRC. This
commit implements the WebSocket sub-protocol as specified by the pending
IRCv3 proposal [1].
WebSocket listeners can now be set up via a "wss" protocol in the
`listen` directive. The new `http-origin` directive allows the CORS
allowed origins to be configured.

This adds support for the WIP (at the time of this commit)
draft/chathistory extension, based on the draft at [1] and the
additional comments at [2].
This gets the history by parsing the chat logs, and is therefore only
enabled when the logs are enabled and the log path is configured.
Getting the history only from the logs adds some restrictions:
- we cannot get history by msgid (those are not logged)
- we cannot get the users masks (maybe they could be inferred from the
JOIN etc, but it is not worth the effort and would not work every
time)
The regular soju network history is not sent to clients that support
draft/chathistory, so that they can fetch what they need by manually
calling CHATHISTORY.
The only supported command is BEFORE for now, because that is the only
required command for an app that offers an "infinite history scrollback"
feature.
Regarding implementation, rather than reading the file from the end in
reverse, we simply start from the beginning of each log file, store each
PRIVMSG into a ring, then add the last lines of that ring into the
history we'll return later. The message parsing implementation must be
kept somewhat fast because an app could potentially request thousands of
messages in several files. Here we are using simple sscanf and indexOf
rather than regexps.
In case some log files do not contain any message (for example because
the user had not joined a channel at that time), we try up to a 100 days
of empty log files before giving up.
