While most of ioctl-related kernel headers are now exported by kernel's
headers_install, some are still modules_install only. The kernel's
headers installed into /usr/include/ are usually headers_install'ed and
therefore don't contain some internal headers we need. The solution is
to look for modules_install'ed headers for the running kernel, and fall
back to old behavior if they aren't found.

Introduce v4l2.c, a decoder for the arguments of the video-input subset
of the v4l2 ioctl's. This is a combination of

- forward port, additions and fixes by Philippe De Muyter <phdm@macqel.be>
As v4l2 is a moving target, I have made v4l2.c compilable with ancient
linux kernels by testing the availability of some macros. It has been
succesfully compiled on linux 3.10, 3.1, 2.6.31 and 2.6.22, and
succesfully used on linux 3.10 with a camera device.

For two ioctl entries with the same code, if one's name is a prefix

X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
32bit pointers. At system call level, x32 is also identical to x86-64,
as shown by many changes like "defined(X86_64) || defined(X32)". The
main differerence bewteen x32 and x86-64 is off_t in x32 is long long
instead of long.

This unifies all the ioctlent.h's in the linux subdir while still
allowing each arch to maintain its own minor list.
The basic method is:
- each arch has linux/<arch>/ioctlent.h.in which defines only the
arch-specific ioctls;
- linux/ioctlent.h.in which defines only the common ioctls;
- at build time, these two headers are combined and sorted to produce
the linux/ioctlent.h file.
This also requires a little tweaking of the include files since the
common ioctlent.h is a built file.

linux/i386/ioctlent.h.in, remove asm entries from the former, remove
