v4l1 (linux/videodev.h) and libv4l

[Kevin Kofler]

Hi,

several of the build failures in Rawhide are due to the removal of v4l1 from 
the kernel, which manifests itself as a missing <linux/videodev.h> header. 
(I think there was a thread about that on this list already, but I can't 
find it now.)

My questions:
* Couldn't v4l1-only apps be made to work with minimal porting effort 
through libv4l's libv4l1compat, without v4l1 support in the kernel?
* libv4l's libv4l1compat itself also fails to build due to a missing 
<linux/videodev.h>. It obviously needs the #defines there to emulate the 
API. Should libv4l ship that header now?
* It's quite embarassing to have libv4l be one of the packages failing to 
build due to a kernel v4l change. Why wasn't this change coordinated with 
libv4l?
