The name had a bit conceptual conflicts with MetaKmsUpdate, as it shared its namespace but had no relation to it. Fix this by renaming it MetaKmsResourceChanges (and the corresponding META_KMS_UPDATE_CHANGE_* to META_KMS_RESOURCE_CHANGE_*). The term "resource" is used since that's already used in the signal, and the fact that the changes partly comes from changes in the DRM resource as retrieved by drmModeGetResources.
