Serialise connection creation against concurrent creation and destruction using a global mutex. This is needed to prevent two drivers from attempting to create a connection to the same interface CPort and to cope with a racing connection destroy when moving to driver managed connections. Note that the locking can not (easily) be made more fine-grained as not all connections have an interface, but these are not hot paths anyway.
