(code from mplayer see their svn for detailed authorship)
parameters must be integers as we do not have mplayers parser
also the stuff passed to it through non constant globals is not supported
this should be fixed in mplayer first.

Add aconvert filter to perform sample format, channel layout, and
packing format conversion.

The aconvert code depends on audio conversion code in libavcodec, so
this requires a dependency on libavcodec.

Based on previous work by S.N. Hemanth Meenakshisundaram and Mina Nagy
Zaki, performed for the GSoC 2010 and 2011.

This list is mainly useful to be directly used as a parameter by the
audio sink buffer, when there is no need to force a specific channel
layout.

The list of formats is generated programmatically, and avoids channel
layouts not supported by libavfilter (with more than 8 channels).

We preferred to avoid compile-time generation in order to avoid some
unnecessary complexity (build hacks, generating code maintainance
etc.).

A more compact way to express this list through the use of macros
should be possible when libavfilter will support more than 8 channels,
as there will be no need to filter out channel layouts with more than
8 channels.

This is done in order to clarify the non-video-specific nature of the
buffersink code, as the result of the video/audio API unification of
the previous commit, and for improving overall consistency.

The new API is more generic (no distinction between audio/video for
pulling frames), and avoids code duplication.

A backward compatibility layer is kept for avoiding tools ABI breaks
(only for the video binary interface, audio interface was never used
in the tools).

The file is going to contain the amovie source, so give it a less
specific name.

The source was natively integrated into libavfilter, with the name
mptestsrc.

The gradfun filter was already integrated natively in libavfilter.
Both filters issue the same output, and have a comparable performance.

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

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

Declaring tools associated with each library in their respective
makefiles allows these tools to easily depend on the correct
prerequisites and link against the libs they need.

This reverts commit a6213f3d.

Calling Make from subdirectories is not supported and config.mak has
multiple inclusion guards anyway, so the top-level include is enough.

Add a missing space between vsink_buffer.h and vsrc_buffer.h.
1000l.

Also add the public interface libavfilter/vsink_buffer.h.
