Add Proximity API
Add Proximity API

Covers the Proximity Monitor for Link Loss, Tx Power and Immediate
Alert services. This first proposal considers that the connections
will be managed by the bluetoothd core based on the registered
connection callbacks.

Only one instance of Immediate Alert service is allowed, "Alert Level"
characteristic of this service is used by Find Me and Path Loss. Note
that "Alert Level" for Path Loss is a LOCAL property written in the
Immediate Alert service when the threshold is reached. For Find Me
the user/application needs to actively enable the alert in the Immediate
Alert service. Link Loss has it's own instance of Alert Level
characteristic.
