* 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.

* updated patch for FLAC 1.2.1 and disabled all ASM optimisations for OSX Intel, as they aren't supported. I object this update and would like to continue using the 1.1.x series of FLAC for this branch.

Patch by Glen Gray: Enable keepalive for Kasenna servers, they parse the User Agent string and check for _KA appended to the User Agent name.

Patch by Glen Gray: RTSP keep alive fix. If the server doesn't handle RTCP-RR packets and requires specific GET_PARAMETER commands (such as Kasenna) then the session times out when vlc is paused because the current version only sends the info when Demux() is called. Demux() is only called when data is received. This patch fixes this issue with a boolean that is set during PAUSED state that allows the timer thread to send the GET_PARAMTER messages instead and thus keeping the RTSP session alive.
