Patches for FFmbc 0.7 rc7

DNxHD in MXF

This patch puts DNxHD into MXF. It is scraped from the recent FFmpeg updates.

Limited testing has been done, but EVS systems have accepted the media, which is all that we needed.

ff_fill_rgba_map() in drawutils

Some of the patches below require the ff_fill_rgba_map() call, so I've added it to libavfilter/drawutils (like it is in FFmpeg)

Martin Weston three field deinterlace filter

Based on the process described by Martin Weston for BBC R&D, and implemented based on the de-interlace algorithm written by Jim Easterbrook for BBC R&D, the Weston 3 field deinterlacing filter uses filter coefficients calculated by BBC R&D to accurately deinterlace an interlaced video.

The results are similar to the yadif filter, but the w3fdif filter is just a tiny bit sharper. Unfortunately it is also a tiny bit slower.

squeeze4to3 and stretch4to3

Using the filter coefficients provided by Tim Borer for BBC R&D, and implementing his algorithm, which this code looks nothing like, these filters are designed to stretch or squeeze video while preserving the quality.

The filters are designed for converting to or from anamorphic video, for instance converting 1440x1080 HD video to 1920x1080 HD video, converting 1920x1080 HD video to 1440x1080 HD video, or pillar-boxing 4:3 video into a 16:9 frame.

Note: this code requires a clean-up, as I've left lots of av_log() statements, use while debugging the code, commented out.

Waveform monitor

Early access to a work in progress.

This filter turns your video into a waveform monitor view. Using the split filter and the overlay filter you can superimpose the waveform monitor on top of your video.

NoteL this code is very early in its life.
