Change support for decompressing ov518 "JPEG" to piping data through an
external helper as I've failed to contact Mark W. McClelland to get
permission to relicense the code. If you know a working email address for
Mark W. McClelland, please let me know.

Add support for decompressing ov518 "JPEG", note this code is not
LGPL yet, I'm waiting for a license change permission. If I do not
get one this will be moved to an external helper and the data
will be piped through this, to keep libv4l2.so LGPL

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

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.

This patch update libv4l's Makefiles so they automatically update and

Support the decompression used by the SQ905C cameras (0x2770:0x905C) and
some other related cameras. There is at the moment no support module for
these cameras in streaming mode, but I intend to submit one.
This contribution was created in whole by me, based upon code in libgphoto2
which was created in whole by me, and which was licensed for
libgphoto2 under the LGPL license.

Recent sn9c20x driver written by microdia project
(http://groups.goolge.com/group/microdia) introduce new output format -
sn9c20x-i420. This format is actually scrambled yuv420, so it's very easy and
fast to convert it to yuv420. This patch adds sn9c20x-i420 decoder to the
libv4l-0.5.7
This decoder is much faster than jpeg one (sn9c20x supports JPEG too):
sn9c20x-i420 decoder eats only 10% of 1GHz CPU at 640x480x25fps vs 40% of
1GHz CPU in jpeg at same frame size/rate.
This format should be preffered for sn9c20x, because sn9c20x driver supports
SBGGR8 too, so it should go before SBGGR8 in supported_src_pixfmts.

* Add support for software cropping from 352x288 -> 320x240 / 176x144 ->
160x120, so that apps which will only work with vga resolutions like
320x240 (Skype!) will work with cams/drivers which do not support cropping
CIF resolutions to VGA resolutions in hardware. This makes all 2.6.27 gspca
supported cams, except for the pac7302 which only does 640x480 (and skype
wants 320x240), work with skype
* The v4lconvert_convert function was becoming a bit of a mess, so split the
functionailiy into seperate v4lconvert_convert_pixfmt, v4lconvert_rotate and
v4lconvert_crop functions, and make v4lconvert_convert a frontend to
these

Instead of having libv4l2util in v4l2-apps/lib and libv4l in v4l2-apps/lib/libv4l,
both are now moved to v4l2-apps/libv4l2util and v4l2-apps/libv4l.
This is much cleaner and less confusing.
