Title:
  [SRU] pulseaudio-droid module crashes on start

Status in pulseaudio package in Ubuntu:
  Invalid
Status in pulseaudio source package in Xenial:
  Fix Released

Bug description:
  Ubuntu 16.04 Xenial, and pulseaudio version 8.0-0ubuntu3.4

  [Impact]

   * This bug prevents users (currently Project Halium, UBports, Plasma Mobile) from using the pulseaudio-modules-droid on android devices.
   * This behavior can be seen in Ubuntu Xenial 16.04 with xenial-updates enabled.
   * Last 3 releases of pulseaudio included multiple patches which modified behavior of pulsecore library but required changes were not made in pulseaudio-module-droid.
   * This results in crash in pulseaudio-modules-droid

  [Test Case]

   * Start pulseaudio
   * From another session run pacmd
   * In prompt type load-module module-droid-discover
   * On ubuntu touch devices, it will crash at startup

  [Regression Potential]

   * There is no regression potential for other parts of pulseaudio
  components.
