Implement more full resource policy features.

 * Handle released by manager properly.

Signal resourcesReleasedByManager is different from signal
handleResourcesLost and needs to be handled separately.
Signal handleResourcesLost means some other client has acquired the
resources, thus the resources are lost from us, but if the other client
frees the resources, we will automatically get the resources back.
With resourcesReleasedByManager we lose the resources, and resource
manager releases them as well (same as if client would call release()),
so only way to re-acquire resources in latter case is calling acquire()
again.

This distinction is useful for example in cases where user is listening
to music with headphones connected and removes the headphones, then the
music player shouldn't continue playback until user requests so. But if
user is listening to music when phone call is received, it is convenient
to resume the playback automatically after the call.

 * Implement availability changed.

Availability changed is information whether resources the client is
interested in are available (no higher priority resource classes have
acquired the resources).

 * Implement missing resources released.

Emit resourcesReleased signal when receiving corresponding signal from
libresource-qt.

 * Add mechanism to change used resource class.

Check for environment for special variable, and if the variable has
proper data, use that as the resource class. Can be set with for example
qputenv("NEMO_RESOURCE_CLASS_OVERRIDE", "game");
