  lavf: deprecate now unused AVStream.pts

Conflicts:
	libavformat/mux.c
	libavformat/version.h

mostly not merged as the code is needed for a/vsync drop handling
and what the code does is what is needed, it could maybe be moved
elsewhere or factored somehow but simply removing it would be droping
these features.

 API changes, most recent first:
 
+2014-05-xx - xxxxxxx - lavf 55.17.1 - avformat.h
+  Deprecate AVStream.pts and the AVFrac struct, which was its only use case.
+  Those fields were poorly defined and not meant to be public, so there is
+  no replacement for them.
+
 2014-05-18 - fd05602 - lavc 55.52.0 - avcodec.h
   Add avcodec_free_context(). From now on it should be used for freeing
   AVCodecContext.
