Initial changes to support a nexthop with multiple backups. Lib
changes to hold a small array in each primary, zapi message
changes to support sending multiple backups, and daemon
changes to show commands to support multiple backups. The config
input for multiple backup indices is not present here.

Reported that in certain config changes, a static intended for the
default table would be duplicated into a vrf context. Determined
that we still weren't keeping or adding the exit-vrf command when
necessary to keep the contexts straight. Added logic to look for
the failing circumstances and add or remove the delete of the
exit-vrf command as needed.

* add a vrf sub-command `[no] ipv6 router-id X:X::X:X`.
* add command `[no] ipv6 router-id X:X::X:X [vrf NAME]` for backward
compatibility.
* add a vrf sub-command `[no] ip router-id A.B.C.D` and make the old
one without `ip` an alias for it.
* add a command `[no] ip router-id A.B.C.D [vrf NAME]` for backward
comptibility and make the old one without `ip` an alias for it.
* add command `show ip router-id [vrf NAME]` and make
the old one without `ip` an alias for it.
* add command `show ipv6 router-id [vrf NAME]`.
* add ZAPI commands `ZEBRA_ROUTER_ID_V6_ADD`,
`ZEBRA_ROUTER_ID_V6_DELETE` and `ZEBRA_ROUTER_ID_V6_UPDATE`
for deamons to get notified of the IPv6 router-id.
* update zebra documentation.

This commit avoids freeing the iptable context, once created. the case
where there is an error when reading zapi stream simply needs to free
the zpi context.

During perf testing of receiving and installing 7.5 million
routes into zebra it was noticed that memset in bgp_zebra_announce
was taking ~11% of the runtime. With this change bgp_zebra_announce
now no longer has any appreciable time spent in memset as reported
by perf. In addition bgp_zebra_announce run time in perf was
reduced by a composite amount.

We do not need to know anything about rules in afi 128/129
at this point in time. Just note it with a zebra kernel
debug and move on. This is not something that a operator
can do anything with and at this point in time FRR
does not care.

Include any installed backups when updating the local kernel
after processing an async notification. This includes routes'
nexthops and LSPs' nhlfes.
Add the 'b' character to the route show display and header to
indicate backup nexthops.

Fix the function encoding evpn neighbor. The size of the buffer
for the netlink message wasn't correct and because of that we thought that
the message didn't fit entirely in the buffer and thus we were not sending
the update to the kernel.

When creating a pim instance, we were allocating table information
