* don't check authentication if the network doesn't need to
register
* don't pass through muser for ZNC type messages
* avoid duplicate message for queries containing highlights
* make a copy of the cast for metadata analysis to avoid poisoning it
* set up callback for when the instance is authenticated, so we can
request a LIST immediately if so desired
* separate out seeding functions to populate CHANLIMIT to ease future
work involving other options, such as PREFIX
* Work around Twisted's broken handling of spaces
* Work around Twisted's broken line decoding
* Don't run signedOn twice for relays
* Improved detection of whether the endpoint is connected to ZNC
* Delay a LIST until all configured relays are online
* Discard a LIST if there are no callbacks for it
* Get rid of some double-negative ternary blocks
* Always use simple LIST syntax if it succeeded once after a failed
complex query
* Reject asking for a LIST twice
* Quickly discard any ISUPPORT messages that don't contain things we
need to use
* Detect the server name and drop any messages from the server
* Implement a nick -> user mapping, preventing a superfluous SSCAN on
the entire dataset for when networks are disconnected
* Use one thread for all channels when a network instance is
disconnected, instead of one thread per channel
* Made returns comprising of only a list into tuples
Fix a bug where the channel allocation algorithm failed due to
necessary relays not having been provisioned yet.
Passed the newly created relay numbers to the allocation function
and assumed their CHANMAX would be the same as all other relays for
the same network.
