Add support for opening multiple devices in v4l2_open(), and for
mapping controls between devices.

This is necessary for complex devices, such as Nokia N900.

Ping?

There's a lot of work to do on libv4l2... timely patch handling would
be nice.  

As we're be start working at the new library in order to support
complex cameras, and I don't want to prevent you keeping doing your
work, IMHO the best way to keep doing it would be to create two
libv4l2 forks:  

BTW.. new library. Was there decision what langauge to use? I know C
is obvious choice, but while working on libv4l2, I wished it would be
Rust...

Rewriting same routine over and over, with slightly different types
was not too much fun, and it looked like textbook example for
generics...

Whatever language it uses, the library should provide a standard C API
interface and avoid using libraries that may not be available on
the systems supported by the v4l-utils package, as other packages
and a libv4l-compatible interface should be linked using it.

It should also be something that the existing v4l-utils developers are
familiar with. Right now, we have only C and C++ code inside v4l-utils.

So, I'd say that the language should be either C (the obvious choice)
or C++.

It should also be licensed using the same terms as v4l-utils libraries,
e. g. LGPL 2.1+.

Thanks,
