Steve Reinhardt c2cce96a0b sim: fail on implicit creation of orphans via ports
Orphan SimObjects (not in the config hierarchy) could get
created implicitly if they have a port connection to a SimObject
that is in the hierarchy.  This means that there are objects on
the C++ SimObject list (created via the C++ SimObject
constructor call) that are unknown to Python and will get
skipped if we walk the hierarchy from the Python side (as we are
about to do).  This patch detects this situation and prints an
error message.

Also fix the rubytester config script which happened to rely on
this behavior.
