bfd_recv_ipv4() is getting an uninitialized buffer passed in as port,
and then checks it without clearing it first. Thus we can end up
leaving garbage data in it.

Clang was thinking the random level could be negative. (And, no, I
couldn't figure that out by reading its output... trial and error this
was.)

Add a TAILQ_POP_FIRST so Clang understands it's the same item that is
getting removed from the list.

'show debugging' is returning a Command incomplete
error message as that it is being sent to staticd
and staticd has no knowledge of it, fix this.

Debugging inactive nexthops in zebra can be quite difficult
and non-obvious what has gone wrong. Add detailed rib
debugs for the cases where we decide that a nexthop is
inactive so that we can more easily debug a reason
for the failure.

The _route_entry_dump function was not handling the nexthop as passed
in from an upper level protocol appropriate and as such not displaying
the v4/v6 nexthop right in the case where we have both going.
Additionally dump the nexthop vrf as well.

The RB-Tree used to store rmac information was not properly
handling the v6 address family. Modify the code to allow
this handling.
Cleans up this error message:
zebra[2231]: host_rb_entry_compare: Unexpected family type: 10
That is being seen, This fixes some connectivity issues being seen.

The log function would improperly format a string using an integer
causing a crash. This situation was found when switching echo mode with
a active connection.

The ZEBRA_IPV4_ROUTE_IPV6_NEXTHOP_ADD zapi message has no creators and
no handlers. Let's just remove.

Avoid all complexities of handling ethernet/IP/UDP headers and just use
UDP sockets: let the OS kernel handle this task.

Enumerate all codes, update the string representation and fix the
misdiagnosed echo failure.

We'll reuse these functions later to receive echo packets, so we need
to despecialize them first. Another improvement here is that we are
going to remove the global buffer variable and opt to use the stack.

Remove all VxLAN code. There are probably better ways to write VxLAN
support without having to use raw sockets and depend on extra user
configuration input.
