split out the libmp4v2 part from mpeg4ip -- all users in the pkgsrc

tree just need that library, the player in mpeg4ip just causes an unwanted
dependency on SDL and complications due to plugin building

+The MPEG4IP project provides a standards-based system for encoding,
+streaming, and playing encoded audio, video and text. To achieve
+this we've integrated a number of existing open source packages,
+and created some original code to fill in the gaps.
+
+Please note this project is intended for developers who are interested
+in standards based audio and video, and Internet streaming. It is
+not intended for end-users.
