a2cb4daa46 relay: mangle the mode name when forwarding extban->cmode so that +b syntax filters don't trigger 
This should allow bidirectional forwarding between UnrealIRCd +b ~T:block:<glob> and InspIRCd +g <glob> to work.

8fcb5f9df0 relay: ignore static extbans when looking up dynamic extban prefixes 
This fixes #560, which was caused by relay confusing ban_all_registered ($a) with ban_account ($a:), since $a:account also starts with $a.

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.

fa30d3c732 relay: rework fallback message routing to be less annoying (#384) 
- PRIVMSGs from users not spawned on a network are sent via the main PyLink client in the format "<$orignick/$network> <$text>"
    - <PyLink> <user/net> blah blah
- NOTICEs from users use the same format above, and are routed from the relay subserver representing the network that the message originated from
    - Notice(somenet.relay): <user/net> blah blah
- PRIVMSGs from servers are blocked, because they aren't valid on all IRCds and are fairly obscure anyways (suggestsions/improvements welcome)
- NOTICEs from servers are forwarded as raw text, from the relay subserver representing the origin network
    - Notice(somenet.relay): some server announcement
