PM: ShillProvider now provides the connection tethering mode.

This adds a connection tethering variable to the RealShillProvider.  In
doing so, we:

* Query the default service attributes (type, tethering) eagerly, as
  soon as a default service signal is received (but only if the default
  service has actually changed).

* All variables are reduced to CopyVariable instances, migrating all
  DBus communication logic into the RealShillProvider and eliminating
  the ShillConnector helper class. This also allows us to turn variables
  into contained members and initialize them during construction.
