initialize the message layer
OSMMsgOpenCall initializes the message layer.
This function takes no arguments.
OSMMsgOpenCall should be called by
each OSM as one of the first actions
in its open routine.
It need only be called once per OSM
(if opened multiple times), but multiple calls cause no problems.
Does not block.
Driver-defined basic locks, read/write locks, and sleep locks may be held
across calls to this function.
