[PATCH 0/2] Add device statistics interface

[Alfonso Sanchez-Beato <alfonso sanchez-beato canonical com>]

This patch set add a statistics interface for each device so clients can
be notified of current network activity. This happens by
PropertiesChanged signals, which are generated when the measured
magnitudes change, with a minimum time between signals determined by
the RefreshRateMs property. Also, when this property is set to zero,
the interface gets deactivated and no more signals are generated.

These patches are an initial implementation looking for comments. The
underlaying mechanism used to track activity is netlink routing sockets.
For the moment, TxBytes and RxBytes are the only magnitudes measured.
