[gst-plugins-base] patches for avidemux and gstv4l2sink

without these patches the communication between the plugins was not
functional after the transition from READY_TO_NULL back to NULL_TO_READY.

NOTE: The patches are already posted to bugzilla for mainlining and
hopefully will not be needed anymore in further releases.

+Subject: [PATCH 1/2] [gstavidemux] reset the have_index flag at transition PAUSED_TO_READY
+
+If we restart the Stream in the case of doing a transition from
+PAUSED_TO_READY and back with READY_TO_PAUSED aso. the duration of the video
+will get calculated even if we have a avi header with that information.

+Subject: [PATCH 2/2] [gstv4l2sink] destroy open buffers when changing to NULL
+
+In the case we change the State from READY_TO_NULL the open buffers
+still hold a open dup filedescriptor to the device, therefor the device
+release function will not be called and the device probably answer with
+-EBUSY when we reopen it at transition NULL_TO_READY.
