Move phonon outside of KDE4

[Fathi Boudra]

Hi,

As many people know, Phonon will be included in the upcoming Qt4.4.0 as
their multimedia framework.
They share the framework with KDE4 and the source code is in KDE repository.

I plan to move phonon outside of kdelibs and phonon backend plugins outside
of kdebase-runtime.
The idea is to make available Phonon to pure Qt programs  and developers.

At least 3 packages are needed:
* libphonon - runtime library
* libphonon-dev - development files (includes, etc...)
* phonon-backends - phonon backends plugins (xine and gstreamer)


This is a draft to have a starting point of discussion to receive feedbacks
from the involved maintainers.
