Functional as is, but still work-in-progress in the
sense that some things need to be fixed before sending
it as a patch to SVN.

Rework link property configuration system.
This can now handle filters which are added to graphs out of order,
including auto-inserted scale filters. As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.

Use separate fake filters for exporting inputs and outputs from filter graphs.
This makes the code a little less confusing, and is needed for the patch to
improve the link configuration process, to be committed next.
