[PATCH 1/7] Bluetooth: Add RSSI Monitor commands

[anderson.briglia@openbossa.org]

From: Anderson Briglia <anderson.briglia@openbossa.org>

This patch adds two new Management commands: Enable/Disable RSSI Monitor.
These commands are used to handle a list of RSSI monitors, that are
responsible to watch RSSI values from a connection. It is useful for
Proximity profile implementation.
