PM: Shift to signal-based inference of network connection.

Instead of making DBus calls to shill on-demand, and estimating the time
a connection has changed, the RealShillProvider now listens to the
appropriate DBus signal and update its internal state accordingly. Note
that checking for the connection type still requires a DBus call, if the
connection has changed since its type was last checked.

In order to pass all unit tests (including those of PolicyManager and
RealState), there's a substantial portion of DBus mock set up code that
was added. This code will be removed very soon, once we begin injecting
providers into RealState, instead of low-level DBus and/or clock
interfaces.
