Use UPower namespace as default DBus name preserving old one
Expose the daemon as org.freedesktop.UPower.PowerProfiles
by default
but we also own the old net.hadess.PowerProfiles
name for
compatibility resons.
Also dbus objects are now registered also in the path
/org/freedesktop/UPower/PowerProfiles
and they implement the
org.freedesktop.UPower.PowerProfiles
interface.
Even in this case we preserve the compatibility with the old ones.
To make this switch as most reliable as possible, the code is now generated for dbus configuration files preserving the previous ones as base.
Tests are now performed checking both names, to ensure again that we're not breaking the expectations for the old APIs consumers.
