blackframe is integrated as a native filter.

The cropdetect filter is natively integrated into libavfilter.

The filter was integrated natively into libavfilter as a source with
name rgbtestsrc.

The licence was changed from GPL to LGPL with explicit approval from
the original author.

See thread:
Subject: [FFmpeg-devel] [PATCH] lavfi: add rgbtestsrc source,
        ported from MPlayer libmpcodecs
Date: Mon, 11 Jul 2011 16:32:41 +0200

It is natively included in libavfilter.

With the following additions:
* support to gray format
* support to yuva420p format
* parametric luma/chroma/alpha radius
* consistency check on the radius values, avoid crashes with invalid values

Also add a "dar" alias for "a", for avoiding confusion with sar/dar.

Also create a "dar" alias for the "a" variable, for avoiding possible
confusion between dar/sar.

Also add the public interface libavfilter/vsink_buffer.h.

This filter is a simple wrapper around the LUT filter.

Correct the name from "remove_logo" to "remove-logo".

Address trac issue #92.

Avoid the need of two distinct av_vsrc_add_video_buffer_ref*
functions. Simplify the interface.

Indeed the Adler-32 checksum, which is computed by showinfo, is not
cyclic, so using the term "CRC" is wrong/confusing.
