Update phonon to 4.8.2

4.8.2
* Revised the logic used by PulseSupport to come up with an icon name
  for PulseAudio. If the application has QApplication::windowIcon set
  with an QIcon constructed through QIcon::fromTheme(string) the actual
  icon name will be used. Otherwise the lower-case version of
  QCoreApplication::applicationName is used.
* Fixed building with the compiler clang by reverting a previously
  introduced workaround.

4.8.1
* Prevent a crash when failing to create the preferred backend

4.8.0
* Prevent problems with the CMakeConfig's relative installation path
  resolution when trying to build on a system which has symlinks as part
  of the installation path (e.g. Fedora systems).
* Prevent warnings on PulseSupport shutdown when AudioOutputs are held by
  a global static that is only destroyed after PulseSupport was shut down.
* Sync clang detection code with kdelibs.
* Documented the fact that paused can result in StoppedState if playback
  can not be started.
