It has videodev2.h, but I guess they didn't want to introduce a
/usr/include/linux subdir - so videodev2.h is found in /usr/include/sys.

At the moment, Solaris only supports usbvc camera devices, and I've only seen
UYVY and JPEG output, neither of which are 'camera specific'

I think we definitely want to keep the #ifdef code paths and not add a hard
dependency on libv4l.
