73d0e153cf relay: support relaying kills (#520) 
Instead of always bouncing, kills to a relay client are now handled as follows:

1) If the target and source networks are both in any killshare pool, relay the kill entirely
2) Otherwise, iterate over all channels the kill target is in:
    3) If the killer has claim access in a channel, forward the KILL as a kick
    4) Otherwise, bounce the kill (so far, silently)

TODO: kill messages are currently very cluttered, we should make our parser deliver more concise strings...
* GL|unreal has quit (Killed (chary.relay (KILL from GL/chary: Killed (GL (test)))))

9466813ba1 relay: switch to a flexible, pool-based configuration scheme for IP sharing 
This deprecates the "relay::show_ips" and network-specific "relay_no_ips" options, replacing it with the "relay::ip_share_pools" list.

b1248524a9 relay: raise an error when trying to delink a leaf channel from another leaf network 
Previously this would (confusingly) delink the channel from the network the command was called on instead of the intended target.

fee64ece04 relay: fix clientbot op requirement not being checked if the sender is in the target channel 
Also, show a slightly different error when using the command with 'remote', since the clientbot client gets overridden to be the message sender.

c9c937e7a7 relay: block networks not on the claim list from merging in modes when relinking 
This can cause channels to be inadvertently set modes that it shouldn't be on a relink (e.g. modes set by services DEFCON), since relay ignores modes from defined u-lines instead of bouncing them.

e9fe15bd7d [WIP] Further revise the persistent channels implementation 
- Make dynamic_channels per plugin as well as per network to work around relay-service conflicts (#265)
- Introduce ServiceBot.(add|remove)_persistent_channel() to add/remove persistent channels and optionally join/part them
- Introduce ServiceBot.part(), which checks remaining persistent channels list and parts a channel only if it is still not marked persistent
- Refactor automode to autojoin channels on ENDBURST instead of plugin load
- Refactor relay to manage persistent channels on join/part/(de)init, both locally (namespace 'relay_local') and remotely (namespace 'relay_remote')

4a01948647 relay: oops, multiple STATUSMSG prefixes should pick the lowest, not highest (#570) 
This behaviour really isn't consistent across IRCds though...
- Unreal, Hybrid, and charybdis mangle messages at the server side to use the lowest prefix
- InspIRCd throws a "No such nick/channel" error
- Nefarious silently drops messages with multiple prefixes?

81bd1e8474 relay: add basic support for STATUSMSG (#570) 
So far, this code only knows about changing prefixes while keeping mode characters as-is.
A complete but longer solution would be to actually go through irc.cmodes, but I don't
think doing so is necessary given how little STATUSMSG is actually used in production.

d01b9aaa23 relay: improve fallback KNOCK notices 
- Show the network that the /knock originated from (it is *not* obvious when we have a user with no relay client)
- Specifically hint that users with no relay client cannot be invited directly because there is no client to actually /invite!
- Prefer sending the notice to %#channel when halfops are available, as they usually have the power to /invite

4a6f94f8fc relay: add workarounds for u-lined servers 
- Allow ulines to join with modes (this status gets forwarded as part of relay_joins()), but *ignore* this status when checking for claim
    - For U-lined clients to set modes properly and kick, they be on the claim list
- Allow ulines to set modes on ulined clients including itself. These changes are ignored: not forwarded, not bounced, but just left there.
- Ignore uline attempts to set non-list modes - this is mostly for compatibility with Anope's DEFCON, as it would otherwise lead to a mode flood.

This requires commit 9113b34b46, i.e. the get_server() update.
