This is the first drop of those commits.  The files have
changed too much and the diffs to extensive to try to do it
in one piece.  Break it up into smaller code chunks.

896af92e5b vtysh: work around gcc bug #69981
The memtypes changes break gcc -O0 build (none of the other optimisation
levels are affected, *any* of -Og, -Os, -O1, etc. make this go away).
Unfortunately, the option supposed to control this doesn't actually work
(-fno-keep-static-const; that not working is the actual gcc bug).

The workaround is to avoid DECLARE_MTYPE statements when their paired
DEFINE_MTYPE isn't linked in.  Thankfully, that's only a problem in a
single place in vtysh where bgp_memory.h gets chain-included.
(vtysh.c -> bgp_vty.h -> bgpd.h -> bgp_memory.h)

So, this just breaks the chain at bgp_vty.h.

No other compiler (clang & icc tested) has exhibited this problem.

4a1ab8e405 *: split & distribute memtypes and stop (re|ab)using lib/ MTYPEs
This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.

The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.

bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use.  This is bad practice and would break when the
memtype are made static.

8c4f63817a bgpd: Process directly connected IBGP peers upon interface down
When we have a single-hop BFD session for any peering, it really means
that the peering is directly connected (maybe over a L2 network), whether
it is IBGP or EBGP. In such a case, upon link down, immediately process
IBGP peers too (and bring them down), not just EBGP peers.

This change eliminates some peculiar state transitions in specific IBGP
topologies, thus getting rid of the problem of nexthops remaining inactive
in the zebra RIB.

a60b9a3718 bgpd: Fix route install upon multipath nexthop change
In multipath selection, there can be a scenario where the set of route
entries selected as multipath can be the same (i.e., from the same peers)
but one or more of these may have a change to the BGP next hop. In this
case, the route needs to be installed again in zebra even if the best
route entry selected has not changed, otherwise the zebra RIB may have
a different set of next hops (and first hops) than what the routing
protocol selected.

This patch handles this scenario by re-installing the route if any BGP
attribute has changed for any of the multipaths. Not all BGP attributes
are of relevance to the zebra RIB, but this approach follows existing
logic used in the code (e.g., when BGP attributes for the best route
entry has changed).

f4b6d7e9bf bgpd: Fix route install upon non-best nexthop change
After BGP path selection, even if the best route entry selected has not
changed, ensure that the route is installed again in zebra if any non-best
but multipath route entry has a nexthop resolution change.

In the absence of this fix, if a non-best multipath route entry had a
nexthop resolution change (such as being resolved over two first hops instead
of one), the route would get reinstalled into zebra only in some situations
(i.e., when the best route entry had its IGP change flag set). If the route
does not get reinstalled by BGP, the corresponding route in the zebra RIB
would not have all the first hops.

e5d1e72daa bgpd: Upon interface up (update) only kick-off non-Established peers
Any interface flags/parameter change (e.g., MTU, PROMISC flag change) is
notified by zebra to clients as an "up" event. BGP literally treats this
as the interface coming up and kicks all neighbors on that interface (i.e.,
directly connected peers). When doing so for IPv4 peers on the interface
(numbered or unnumbered /30-/31) or IPv6 numbered peers, peers that may
already be Established are also flapped; when doing so for IPv6 unnumbered
peers (classic 'neighbor swpX interface' scenario with no configured IP
address on interface), only peers not in Established state are processed.

This patch fixes the code to ensure that in all cases, only non-Established
peers are kicked.
