But command 'show ip ospf vrf all graceful-restart helper' will work

bgpd: Used %pBD instead of %pRN
Let's use the natural data structure in bgp for the prefix display
instead of a bunch of places where we call a translator function.
The %pBD does this and actually ensures data is correct.
Also fix a few spots in bgp_zebra.c where the cast to a NULL
pointer causes the catcher functionality to not work and fix
the resulting crash that resulted.

mgmtd, lib: remove batch ids from all messages
Batch IDs are only used to verify that all messages were received and
processed by a backend. It's not necessary to do that as we use reliable
stream transport - messages can't be dropped or received out of order.
This commit also fixes possible race condition that can happen if
one backend process messages slower than other backends.
