vic patches for video4linux support

attached are some small patches to let mbone/vic
detect and make use of video4linux devices including
the webcam drivers recently made available as
multimedia/linux-gspca-kmod and multimedia/linux-ov511-kmod
If there are no objections i will commit them, and also a
BUILD_DEPENDS+= v4l_compat>=1.0.20060801:${PORTSDIR}/multimedia/v4l_compat
line in the main Makefile to set a proper build environment.
In detail, the patches do the following:
+ fix configure to look for videodev.h in the place where it is on
FreeBSD, and disable v4l2 support for the time being as there
is none as far as i know;
+ add -I/usr/local/include in the search path, for the above file;
+ patch the v4l detection module so that it doesn't exit if the driver
does not support mmap, and instead fall back to read()
cheers
luigi
