/** creates a connection which can be used for the rowset given
The function tries to obtain a connection for the row set with the following
steps (in this order):
<nl>
<li>If the rowset already has an ActiveConnection (means a non-<NULL/> value for this property),
this one is used.</li>
<li>If row set is part of a database form document (see ->isEmbeddedInDatabase),
a connection for the respective database is used.</li>
<li>If in the parent hierarchy of the row set, there is an object supporting
the XConnection interface, this one is returned.</li>
<li>If the DataSourceName property of the row set is not empty, a connection for this
data source is retrieved.</li>
<li>If the URL property of the row set is not empty, a connection for this URL is
retrieved from the driver manager.
</nl>
The calculated connection is set as ActiveConnection property on the rowset.
If the connection was newly created by the method, then
the ownership of the connection is delivered to a temporary object, which observes the
row set: As soon as a connection-relevant property of the row set changes, or as soon
as somebody else sets another ActiveConnection at the row set, the original
connection (the one which this function calculated) is disposed and discarded. At this
very moment, also the temporary observer object dies. This way, it is ensured that
there's no resource leak from an un-owned connection object.
@param _rxRowSet
the row set
@param _rxFactory
a service factory, which can be used to create data sources, interaction handler etc (the usual stuff)
