* 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
* Allocate channels to relays only if they have free space based on
their chanlimit value
* Minify channels by removing ones that are already covered before
passing them off to be joined
* Low-key channel joining with incrementally increasing delay
* Spin up needed instances to be able to cover a certain channel space
* Fix provisioning functions to prevent race conditions with lots of
relays being created at once
* Tweakable switchover from covering all channels to only covering
channels with more users than the mean of the cumulative user count
