Subject: [Bluez PATCH v3 0/3] Adding bonded flag to D-Bus property

Currently BlueZ client can't know easily whether a device is bonded or
not. This is causing issues for a number of applications. For example,
in the Nearby Share case, the peer device is paired, but not bonded.
This series will add the "Bonded" property in org.bluez.Device1 D-Bus
interface. Changes are also made in bluetoothctl to show the status of
the bonded flag as well as a list of bonded devices.

Changes in v3:
- Move documentation update to a separate patch
- Add description to bonded and paired
- Add an optional argument to the devices command to filter device list
- Remove paired-devices command

Changes in v2:
- Move one variable declaration to the top following C90 standard

Changes in v1:
- Add "Bonded" to D-Bus interface
- Send property changed signal if the bonded flag is changed
- Show the status of the "Bonded" flag in bluetoothctl
- Add option to show list of bonded devices

Don't worry, I'm fixing it myself.
