Move common code from gluon-mesh-babel and -batman-adv respondd providers to gluon-respondd
In addition this PR contains: - split of gluon-respondd provider into multiple source files - minor additional cleanups in gluon-mesh-babel respondd provider (untested, as the babel respondd provider already doesn't compile prior to these changes...)
