[FFmpeg-soc] libavfilter: port of Imlib2 vhook

[Víctor Paesa]

Hi,

Here I attach a port of the Imlib2 vhook to the libavfilter API for
your kind review/testing.

I have not ported the -C option, as I favour the RGBA options.
The vf_imlib2.c source is diff'ed from /dev/null, as diff'ing from vf_negate.c
produces a less legible diff, IMHO.

The source contains a few usage examples, usable too as test scenarios.

Regards,
Víctor
