- Delete all obsolete src/components/*_load.cxx files
- Remove obsolete DECLARE_FACTORY_ENTRIES within
  src/components/*_entries.cxx

The removed macros evaluate to NULL on the Gaudi side and have been
kept only for backwards compatibility.

endreq is deprecated, and replaced with endmsg.

Did not replace in log files, or READMEs. Two files which are questionable are
   InnerDetector/InDetAlignAlgs/InDetAlignGenAlgs/src/GeoModelTRT.dev
and
   InnerDetector/InDetRecTools/InDetMultipleVertexSeedFinderUtils/src/PVFindingTrackFilter_cxx
