b72420a8aa Revert "NetworkCore: return the server in get_server if the arg was a server" 
The complete implementation of is_privileged_service() in ec3a94c4ca explicitly checks the entity ID type, so this strange hack is not needed.

This reverts commit 9113b34b46.

f87e646f35 core: use the most recent UID if we have an unresolved nick collision / desync 
This is the one most likely to be correct, assuming IRCds deals with nick collisions properly on their own.

335fb352ec classes: ignore errors on duplicate selector.unregister() 
This should really be fixed more thoroughly: there are still some remaining issues after the port to select, with disconnect / reconnect being triggered twice.

a085aed924 Rework irc.users and User() to transparently create a store of nicks -> UIDs 
- This turns IRCNetwork.users into a new UserMapping class, which stores User objects by UID (str) and provides a 'bynick' dict storing case-normalized nicks to lists of UIDs.
- Turn User.nick into a property, where the setter implicitly updates the 'bynick' index and computes a case-normalized version of the nick (User.lower_nick)

5a00454a8d _parse_modes: apply modes to a temporary mode list as we parse them 
Fixes #573.

Old, broken behaviour:
irc.parse_modes('#test', '+b-bb *!*@new.ban *!*@nonexistent.ban *!*@new.ban')
=> [('+b', '*!*@new.ban')]

Fixed:
irc.parse_modes('#test', '+b-bb *!*@new.ban *!*@nonexistent.ban *!*@new.ban')
=> [('+b', '*!*@new.ban'), ('-b', '*!*@new.ban')]

6a90e99de4 IRCNetwork: do not break on socket BlockingIOError 
On non-blocking sockets, recv() raises BlockingIOError instead of blocking when there's no data to be read.
The correct behaviour is to wait and try again instead of breaking the connection.
