Welcome back bluetooth handsfree

For some time (since 11.x or earlier I think) Linux has been without bluetooth for some features, (see for example https://forums.opensuse.org/showthread.php/492282-13-1-32-bit-bluetooth-headphones-pair-but-not-connect-work-on-12-3).

In Leap 42.1 fresh install I just had it working through pulseaudio with my Samsung WEP. (Resisting temptation to use exclamation points.)

Thanks to the BT guys for the effort. An important gap refilled.
