dbaccess: handle URL mark as StreamRelPath in ODatabaseContext

With this, dbaccess can not only load .odb files, but also other ODF
packages as well, as long as the URL's mark (the part after the "#")
contains under what namespace the real .odb is.

This will be used for embedding data source definitions into .odt
documents by Writer in a bit.
