Move common code from gluon-mesh-babel and -batman-adv respondd providers to gluon-respondd

Browse Source 
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...)
