* reverting [23201], part 2, as current m4 files obviously are not compatible with older gettext releases (should have been part of [23368]

* modules/codec/dmo/dmo.c: backport [16784] add MSS2, MSS1, WMVA, WVP2 and WMVP (still using the old dll name scheme).

* modules/access_output/shout.c: Revert [23295], [23317] and [23318] - Autoreconnect mechanism (not all issues are covered yet for bugfix). Reopened #1167 for now

* disable 10.3 usage, as we can't provide a reliable version due to missing testing possibilities and linking issues against the 10.3.9 SDK

* upgraded x264 to the latest revision (701) with a minor patch for Darwin to include recent speed improvements

Always test in decending order of version numbers. Fixes detection of older versions even when newer are available.
