#11 brand-new filter for deinterlacing

[Zdenek Svoboda]

This patch adds another filter - this filter removes
interpolation artifacts visible on the sides of fast
moving objects when capturing in high resolution. It's
based on simple interpolation algorithm => works fast.
I'm using it for 640x480 capturing.

Adopted from the `transcode' project -
http://freshmeat.net/projects/transcode.

Works with 0.5.1

usage: copy patch to the parent directory of your
camserv-0.5.1 and type:
patch -p0 < camserv-deinterlace.patch
(or copy to root of camserv-0.5.1 and use patch -p1)

Don't forget to initiate the filter in your config
properly.
