BlueZ <5.48 does not support Shanwan or Gasia pairing.
This scriptmodule will build & install newer BlueZ 5.50-1 (debian) packages,
needed to allow sixaxis pairing with third-party DualShock 3 controllers
(and improve DualShock 4 compatibility).
The source includes no custom modifications from upstream except
for the inclusion of Raspbian's patches (which are not
intrusive enough to warrant concern about breaking non-Pi systems).
