[PATCH BlueZ v4 0/6] mgmt/device: report link security level to D-Bus clients

["Frédéric Danis" <frederic.danis@collabora.com>]

This series adds connection security-level reporting.
The new MGMT_EV_SECURITY_LEVEL_CHANGED event [1] is documented and
org.bluez.Device1 is updates with new experimental read-only properties
SecurityLevel and EncryptionType.
Those properties can be displayed using "bluetoothctl info".

This is intended to let clients (including test tooling such as btpclient)
observe effective link security changes.
