Export all the read-only values that get returned about a bridge port
such as the timers, the ids, designated_port and cost,
topology_change_ack and config_pending. For the bridge ids the
br_dump_bridge_id function is exported from iplink_bridge.

netns_map_add() does a malloc of (sizeof (struct nsid_cache) +
strlen(name)) and then proceed with strcpy() of name into the
zero-length member at the end of the nsid_cache structure. The
nul-terminator is written outside of the allocated memory and may
overwrite the allocator's internal structure.
This can trigger a segmentation fault on i386 uclibc with names of size 8:
after the corruption occurs, the call to closedir() on netns_map_init()
crashes while freeing the DIR structure.

It seems that I've made a mistake when I exported these, instead of a
space in the end I've put a newline character which is wrong and breaks
the single line output.
