port: ServerStateChecker + module (batch 2 P2)

Verbatim 40250 CServerStateChecker and the ServerStateChecker Python
module replace the stub; PythonBoot owns the instance like
CPythonApplication::m_kServerStateChecker. The fake server gets a state
port that answers CG_STATE_CHECKER the way CInputHandshake and
CInputDB::RespondChannelStatus do; login_flow requests the channel list
after the character list (live: {1: 1, 2: 1}).
