/**
* A name representing an IRC channel on an IRC server, or an IRC user on an
* IRC server, or just an IRC server.
*
* The separator is '%' between the local part (nickname or channel) and the
* server part. If no separator is present, it's just an irc server.
* If it is present, the first character of the local part determines if it’s
* a channel or a user: ff the local part is empty or if its first character
* is part of the chantypes characters, then it’s a channel, otherwise it’s
* a user.
*
* It’s possible to have an empty-string server, but it makes no sense in
* biboumi’s context.
*
* Assuming the chantypes are '#' and '&':
*
* #test%irc.example.org has :
* - local: "#test" (the # is part of the name, it could very well be absent, or & (for example) instead)
* - server: "irc.example.org"
* - type: channel
*
* %irc.example.org:
* - local: ""
* - server: "irc.example.org"
* - type: channel
* Note: this is the special empty-string channel, used internally in biboumi
* but has no meaning on IRC.
*
* foo%irc.example.org
* - local: "foo"
* - server: "irc.example.org"
* - type: user
* Note: the empty-string user (!irc.example.org) makes no sense for biboumi
*
* irc.example.org:
* - local: ""
* - server: "irc.example.org"
* - type: server
