When we need to go through the fake mmap buffer anyways, we can add
fake controls at no cost. So in the case of webcams which only
support non standard pixformats, export fake flipping controls, as this
can be done at no (performace) cost (until the user activates them).

Before this patch libv4l only support 180 degree rotation, which is
hflip and vflip combined, this patch adds support for separate
hflipping and vflipping.

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.

Add support for converting to YV12 planar (next to the already supported
YU12 / I420) and implement RGB/BGR24 -> YU/YV12 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.
