Attached is a patch to add UYVY support to libv4lconvert. It's
obviously a shameless respin of the YVYU conversion routines :P
Tested on a USB Apple iSight, which only supports UYVY.

* Fix a nasty (and stupid) bug in the special try_fmt handling for UVC cams
* Add some more verbose logging of various calls when asking libv4l to log
calls to a file, to assist in (future) debugging

Always do a s_fmt on uvc cams even if this changes nothing, as not doing
the s_fmt triggers a bug in the uvcvideo driver in kernel <= 2.6.28
(with certain cams)

Avoid the use of try_fmt as much as possible on UVC cams, instead use the
results of the enum_framesizes ioctl. This is because:
1) try_fmt actually causes IO with UVC cams making apps which do lot of
querying of device capabilities slow (cheese)
2) some buggy cams don't like getting lots of UVC video probes and crash
when they do

Don't report DQBUF errors when errno is EAGAIN, this fixes flooding the
screen with errors when applications use non blocking mode

Check that s_fmt atleast gives us the width, height and pixelformat try_fmt
promised us, and if not disable conversion

Some drivers (pwc) do not properly reflect what one really gets
after a s_fmt in their try_fmt answer. So update dest format (which we
report as result from s_fmt / g_fmt to the app) with all info from the src
format not changed by conversion.

* 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.
