Import mp4v2-2.0.0 as multimedia/mp4v2.

The MP4v2 library provides an API to create and modify mp4 files
as defined by ISO-IEC:14496-1:2001 MPEG-4 Systems. This file format
is derived from Apple's QuickTime file format that has been used
as a multimedia file format in a variety of platforms and applications.
It is a very powerful and extensible format that can accommodate
practically any type of media.

MP4v2 was originally bundled with mpeg4ip library, but has been
moved into its own maintained library due to a combination of the
cessation of support of mpeg4ip and the usefulness of this library
on its own.
