Feature #313: meta: Add debugfs tables to netlink

Make data from debugfs mcast_flags dumpable via netlink

Description

Debugfs cannot be used in a non-default netns. Also the current implementation of debugfs files requires large blocks of memory to copy the data to userspace.

Instead all data from mcast_flags should be made dumpable via netlink.

This ticket is assigned to the author of the original code. But everyone can implement the required code

Maybe someone has some feedback here:

<T_X> for the multicsat flags I'm currently trying to figure out how to best offer the extra values for the header
<T_X> so far, on the batman-adv side I have added a BATADV_CMD_GET_MCAST_FLAGS. which will dump the extra info first before dumping the table values
<T_X> not sure whether that would currently fit for the framework in batctl though
<T_X> or whether I should provide the mcast flags header information via an extra command, for instance. and do it similar to netlink_print_gateways() in batctl
<T_X> similar to how this function determines BATMAN_IV vs. BATMAN_V
<T_X> hm, or it seems I might be able to fetch extra info via info_callback() in batctl. like the TTVN for transtable_local
