Native pp filter is available.

postproc dependency is also dropped from mp wrapper since it was the
only filter needing that dependency.

hqdn3d was meant to be a more efficient denoise3d filter, is supported
natively, and is faster on my computer thanks to the ASM optimisations.

This is following 568c70e79e.

Native geq video filter is now available.

lavfi/f_setpts.c should allow everything mp=fixpts supports, with a lot
of additional control.

The native tile video filter is now feature equivalent.

The native filter was ported from the MPlayer project when the mp
wrapper didn't even exist, and when mp=hqdn3d was added, it was already
obsolete.

All the rectangle features have been ported to the native drawbox filter,
which has an equivalent syntax.

The filter has been ported to a native libavfilter filter.

Same functionality is provided by libswscale.

It was ported to a native libavfilter filter.

removelogo has been ported to libavfilter, and the wrapper was not
working.

The filter has been ported to a native libavfilter filter.

Most of the code was taken from MPlayer's vf_uninit_filter_chain.

This will allow us to do regression tests on libpostproc.

(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.

The delogo filter has been natively integrated into libavfilter,
simplify.

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

This way it's easier for the programmer to look-up for a specific
symbols (e.g. for checking if it's unused).

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

See thread:

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.

It is natively included in libavfilter.

This avoid a crash with in avfilter_merge_formats() in case one of the
filter formats list has multiple time the same entry.

Thanks to Mina Nagy Zaki for helping figuring out the issue.
