Upgrade opal to 2.2.8 (from 2.2.4) and ekiga to 2.0.9 (from 2.0.4).
These versions are only available from Ekiga.org, rather than from
the traditionally used site VoxGratia.org...
Turn the previously "hidden" knobs into OPTIONS. Make ekiga accept
whatever versions of opal and pwlib are installed.
Take over maintainership, as I plan to use ekiga myself -- unlike
the current maintainer.
