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.

b50ae89acc relay: check service bot status before remote user presence 
add_persistent_channels() is usable regardless of whether the service bot is ready, so we do not need to break if the remote copy of the service bot doesn't exist.

Closes #606.

f3c2149d7a relay: fix variable confusion when managing service bots 
We should be checking for service bot presence locally, and applying changes on the *remote* network.

2f6c8d2938 Revert "relay: shortcut get_remote_user some more; only grab spawn lock if the user doesn't exist" 
This seems to have caused sporadic duplicate user spawns once more (#602)

This reverts commit 0bc24c94b2.

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')

9d21a5269f relay: speed up shutdowns by not manually splitting off every relay server 
The connection will soon be gone anyways, so this is fairly pointless.

5bffe67416 relay: bandaid patch for freezes on startup when there are a ton of networks 
The side effect of this patch is that it makes large bursts *really* CPU intensive. A proper fix for this will hopefully be introduced in the future.

57f77c676d relay: don't show the network name when routing kicks through a server 
This is redundant, as relay has always spawned subservers for quite some time now.

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.

a425f873b5 relay, inspircd: move endburst delay code to a private API 
This is a very specific hack that shouldn't be extended across the protocol module spec. So far, all other protocol modules ignore the endburst_delay option anyways.

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
