Add device monitoring feature (hotplug device detection)

Changes:
- Implement libudev 'monitor' interface to detect hotplug devices.
- Forward udev rules as AFB 'subscribe' args to udev_monitoring
objects.
- Filter retrieved property fields through 'mask' argument from
'subscribe' args.
- Generate detached threads (event loop) and data  context for each
client,
so every user can subscribe for device events with their own udev
rules and receive their desired device parameters.
