MINOR: connection: add conn_init() to (re)initialize a connection

Browse Source 
This function will ease the initialization of new connections as well
as their reuse. It initializes the obj_type and a few fields so that
the connection is fresh again. It leaves the addresses and target
untouched so it is suitable for use across connection retries.
