[PATCH BlueZ v2 0/6] Add Connectable property to org.bluez.Device

[Kevin Dewald <kevin@simpleble.org>]

bluetoothd records whether each advertising report was connectable,
from the Device Found event's Not Connectable flag, and uses it
internally, for example to pick the bearer to connect and to drop
temporary non-connectable devices when discovery stops. Applications
cannot read it over D-Bus, so they have to guess, e.g. from whether the
device has a name, which is wrong for named beacons and for unnamed
peripherals.

This series exposes it as a read-only Connectable property on
org.bluez.Device1 and on the org.bluez.Bearer.LE1 and
org.bluez.Bearer.BREDR1 interfaces, emitted when it first becomes known
and whenever it changes. bluetoothctl prints it in info, and prints
devices that are discoverable but not connectable in red.

Tested with an nRF52840 switching between ADV_IND, ADV_SCAN_IND and
ADV_NONCONN_IND advertising: Device1 and Bearer.LE1 follow each change,
including PropertiesChanged in both directions on a device kept by
continuous discovery, and the non-connectable profiles, which keep the
discoverable flags, are printed in red.

Changes in v2:
- Add Connectable to org.bluez.Bearer.LE1 and org.bluez.Bearer.BREDR1,
  so the LE value is visible for dual-mode devices (Luiz)
- Print discoverable broadcasters in red in bluetoothctl (Luiz)
- Print LE.Connectable and BREDR.Connectable in info
- Document the property type as boolean, like most of org.bluez.Device
- Rebase on master

Kevin Dewald (6):
  org.bluez.Device: Add Connectable property
  org.bluez.Bearer: Add Connectable property
  device: Add Connectable property
  bearer: Add Connectable property
  client: Print Connectable in info
  client: Print discoverable broadcasters in red
