Remake debug system using the shiny new debug from Amarok
Remove Backend::logMessage(). Convert the old Backend::m_debugLevel to Debug::DebugLevel. Small adjustments to the debug things, including null debug. PHONON_VLC_DEBUG env has the same functionality, except for the value 2, where it has some less output. __FUNCTION__ --> Q_FUNC_INFO everywhere Limited testing done, but it's just debug stuff.
