OperServ: per-IP session limiting with exceptions

Browse source 
The connection that puts an IP over its allowance is killed on connect.
The ircd's per-user IP (UID param 7) is now plumbed through UserConnect and
tracked per-IP in the live network view (incremented on connect, released
on quit).

- [session] default_limit sets the base allowance (0/absent = off).
- OperServ SESSION LIST <min> / VIEW <ip> inspect live counts.
- OperServ EXCEPTION ADD <ip-mask> <limit> [reason] / DEL / LIST override
  the limit per IP-mask (limit 0 = unlimited); event-sourced so they
  federate and survive restart, matched most-permissive-wins.

All admin-gated.
