So far Limnoria relied on detecting 'ERROR :closing link' (see doError
in src/irclib.py), but that's not a standard at all, and fails on
Oragono; so we need to do this to check we're disconnected.
Plus, parsing the argument of ERROR is awful in the first place.
setTimeout may be called as a supybot.drivers.poll callback,
which may by the access to supybot.drivers.poll() in _select;
so a crash in setTimeout will propage up to _run(), which would
cause a random driver to be killed because another one failed
and that's bad.
For example:
INFO 2020-05-27T18:40:18 supybot Received SIGHUP, reloading configuration.
ERROR 2020-05-27T18:40:19 supybot Uncaught exception in in drivers.run:

INFO 2020-05-27T18:40:21 supybot Removing driver SocketDriver(Irc object for irchaven).
echo-message ended up in self.state.capabilities_req even though it wasn't
requested, so the bot was stuck in state:
"Waiting for ACK/NAK of capabilities: {'echo-message'}".
prefixes can be rather long, they have rather small cardinality, and
they are repeated a lot in the history; so they take up a sizeable
portion of memory.
And let's also internalize commands and server_tags keys
while I'm at it.
Plugin can opt in to getting echo messages by setting the class attribute
'echo_message = True' if they want to get echos.
This defaults to False in order not to break existing plugins, and because
they usually don't need it (there's outFilter for most cases).
If on an insecure connection: reconnect.
If on a secure connect: store it and do nothing else.
For now, stored STS policies are not read when connecting to an
insecure server.
There's no reason to use it anymore instead of Socket.
It's already missing features compared to Socket, and I don't want to
maintain it anymore so it will keep getting worse.
This change builds all the ircmsg objects directly in irc.reply, with
the original arguments.
A side effect is that if a config var is changed between the initial command
call and the call to '@more', this commit makes it use the old values,
but that shouldn't be too much of an issue.
Closes GH-1405.
I don't see any use for this; and it means a 'channel' converter
called after 'channeldb' returns '#' instead of the actual channel
if it's after 'channeldb' in the arg list and
databases.plugins.channelspecific is False.
The connect() method already adds it, so it was in the list twice
(added both by __init__() and connect()).
This caused _select() to call _read() twice on the same instance,
except there is usually nothing to read on the second call,
so it blocks for up to conf.supybot.drivers.poll().
Fixes c1d3bad64f, which crashed with:

To prevent infinite recursion on startup, because defaultHttpHeaders
gets the value; which is unset, so 'registry._lastModified > self._lastModified'
is True, so .set() is called, so .setValue() is called again.
Parsing the config file needlessly requires an extra read of it,
and is brittle (extra spaces, etc.)
It was especially broken as there was a newline character
at the end of currentLocale, which made everything fail
shamefully.
