CLI: Dumping internal data structures to files, not to debug output

Browse Source 
All the 'dump something' CLI commands now have a new mandatory
argument -- name of the file where to dump the data. This allows
for more flexible dumping even for production deployments where
the debug output is by default off.

Also the dump commands are now restricted (they weren't before)
to assure that only the appropriate users can run these time consuming
commands.

Dump contents of internal data structures to the debugging output. Truncates the given file and dumps contents of internal data structures
there. By sending SIGUSR1, you get all of these concatenated to
<cf/bird.dump/ in the current directory. The file is only readable for
the user running the daemon. The format of dump files is internal and
could change in the future.
