Subject: [PATCH] Work without permission to access local node's /dev/fw*

Fix for juju backend:

libraw1394 required write permission to the character device file of
the local node(s) in order to enumerate cards and for a number of
other operations.  This forced users to either run applications like
dvgrab and kino with elevated privileges, or to configure write
permission for all /dev/fw* or at least for local nodes' /dev/fw*.

We now use the first accessible file which was found for each card
for as many tasks as possible, instead of the local node's file.

This allows distributors or admins to implement stricter access
rights (default off, e.g. only on for AV/C and IIDC devices)
without sacrificing functionality of said class of applications.
Access to the local node is now only required by low-level tools
like gscanbus.
