Revision 1731866

ACE-532 - use more R6 whiteboard goodies:

- simplify the authentication configuration: instead of configuring it per
  endpoint, use a single servlet context helper that only needs a single
  configuration. Patch supplied by @brampouwelse;
- fix the itests to include the new servlet context helper;
- Clean up the remnants of the old endpoint configuration parts that was
  lingering around after all the changes for ACE-532;
- fix up a couple of license headers where missing.
