Import opal-3.4.1 stable release to replace devel/opal-devel

OPAL is the "next generation" of OpenH323 that has a new architecture.
Not only does it support H.323 and SIP, but new VoIP protocols or
devices can be added very easily.
BTW: OPAL is an acronym for Open Phone Abstraction Library, but
that is not really important :)
