Change controls shm segment name to include the username, as it is only
writable by the user (this means libv4l controls are per user)

Add a patch by Hans Petter Selasky <hselasky@freebsd.org>, which should
lead to allowing use of libv4l (and the Linux webcam drivers ported
to userspace usb drivers) on FreeBSd, this is a work in progress

add gamma correction to the video processing, and enable it by default
(correct for a display gamma of 1.5) for pac207 based cams.

Add software autogain / exposure, for camera's which have gain and
exposure controls but do not contain the ability to calculate the average
lumination in hardware (which is needed to do this in the kernel). This
patch enables this for the spca561 rev12a, but it should be usefull for
other cameras too.

Rewrite video processing code to make it easier to add more video filters
(and with little extra processing cost). As part of this the normalize
filter has been removed as it wasn't functioning satisfactory anyways

Unless the source format of a conversion was a format supported to do
processing on we would update the processing parameters each frame instead
of every 10 frames

As the version number shows this work is the basis for a beta release of the
0.6.x series, the big change here is the addition of video processing to libv4l
currently this only does whitebalance and normalizing (which turns out
to be useless for most cams) but the basic framework for doing video
processing, and being able to control it through fake v4l2 controls using
for example v4l2ucp is there.
The initial version of this code was written by 3 of my computer science
students: Elmar Kleijn, Sjoerd Piepenbrink and Radjnies Bhansingh.
This initial hg commit is a cleaned up and somewhat bug fixed version of
their code.
