First Out Of Band PTS test

Implementation of SM/MAS/SCOB/BV-01-C

This is first LE Pairing test that is establishing bond multiple times.
In order to make it work, bond removal had to be fixed, together with
link timer. Up till now, the LE connection was kept 20 seconds after
last use. After this patch, the link timeout is only one second, just
like the current android behavior.
