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.

We might need to double check this - I'm seeing this:

$ powerprofilesctl 
Failed to communicate with power-profiles-daemon: g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such method “Get” (19)

Expose the daemon as org.freedesktop.UPower.PowerProfiles by default but we also own the old net.hadess.PowerProfiles name for compatibility resons.

Do you have any explanation as to why this was done?

It was something we also discussed in our call, but the point is to advertise p-p-d in the bus as an official FDO project as it is.

The previous namespace will stay in the future, but I also think it's fair to own the fdo name now.
