Subject: [PATCH BlueZ 1/2]     core: Add AlwaysPairable to main.conf

commit 1880b299086659844889cdaf687133aca5eaf102
Author: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
Date:   Fri Jul 27 11:14:04 2018 +0300

core: Add AlwaysPairable to main.conf

This adds a new option called AlwaysPairable to main.conf, it can be
    used to enable Adapter.Pairable even in case there is no Agent
    available.

Since that could be consider a security problem to allow pairing
    without user's consent the option defaults to false.
