[GnomeMeeting-devel-list] V4L device detection

[PUYDT Julien <julien puydt laposte net>]

Hi,

this is a hack to make it possible for the V4L plugin to detect the
devices each time refresh is clicked.

It fixes the following problem:
* start gm with your webcam;
* your webcam is in the list;
* disconnect your webcam (or remove its driver from the kernel);
* refresh
* the webcam is still here!

I call it a hack because it makes the detection do things it wasn't
designed to do. I think that would need a clean rewrite.
