Two changes for `delete_global_type2_routes()`:
1) Remove check of `bgp_dest_has_bgp_path_info_data(rddest)`.
It is unnecessary(`dest->info` should not be NULL) and misleading.
`if (rddest && bgp_dest_has_bgp_path_info_data(rddest))`
Use (locked) node with this check, but unlock with `if (rddest)`,
The mismatched condition is misleading, there seems to be a
mistake to extra unlock.
Just make it clear, immediately exit with `(!rddest)`.
2) Remove checking returned value for it, and use `void` as return type.
It is unnecessary and wrong. Even the check failed, it should continue
to delete other types of routes.
Just remove the check and go through.

Memory is allocated for a `struct prefix_ipv6` but
it was directly copied into a `struct prefix` via
direct pointer copy, which leads to a read past
end of memory. Fix by using prefix_copy

RFC 7471 Section 4.2.7:
It is possible for min delay and max delay to be the same value.
Prior to this change, the code required min < avg < max. This
change allows min == avg and avg == max.
test case:
interface eth-rt1
link-params
delay 8000 min 8000 max 8000

Fresh ground-up MLD implementation with subscriber-tracking for MLDv2.
Intended to be adapted for IPv4 and replace the IGMP implementation at a
later point.
Tested in ANVL, currently at 94/116. Some issues/TODOs are left in the
code as CPP_NOTICE markers, but the code is very much good enough to
proceed since otherwise we're blocked on overall PIM v6 progress.

This is causing build issues on BSD by including (transitively)

The IPv6 `mrt6msg` kernel pseudo-header does not have a length field;
accessing what would be the IPv6 payload length reads zeroes.
Pass down the proper length and use that instead.

After two single-hop sessions (*no local address are configured*) on two
interfaces are UP, remove one address of one interface, both of them
(actually, quite independent sessions) come to be DOWN, not just one.
Consider two boxes: A with `a1` and `a2` adddress on two interfaces,
and B with `b1` and `b2`.
Two sessions are set up and ok: `s1` with <a1,b1> and `s2` with <a2,b2>.
After `a1` of A is removed, there is an unhappy coincidence:
1) On A: `s1` changes local address, and sends <a2,b1> packets with help
of route.
2) On B: wrongly regarded <a2,b1> packets with non-zero remote descriminator
as part of `s2`, and are dropped for mismatched remote remote descriminator.
3) On A: `s1` sends <a2,b1> packets with zero remote descriminator to
initialize this session.
4) On B: wrongly regarded <a2,b1> packets with zero remote descriminator as
part of `s2`. Then `s2` will vibrate.
So the good sessions are overridden.
In this case, the <a2,b1> packets with zero remote descriminator won't take
effect until the current good sessions become bad.
Since single-hop sessions are allowed to be set without bound inteface in
current code, this commit adds one check in `bfd_recv_cb()` to avoid wrong
override.

Peer groups when various forms of `bgp capability extended-nexthop`
is entered on them are toggling the nexthop tracking status of peers
in their peer group. This is ok when the peer is not interface based.
But it is not ok when the peer is interface based as that it will turn
off the ability of FRR to properly work with that peer type.

FRR is displaying that the peer enhanced capability command is not
turned on when the interface is part of a peer group. Saving the
config and then reloading actually turns it off.
Fix the code so that FRR does not display the enhanced capability
for interface based peers.

Firstly, *keep no change* for `hash_get()` with NULL
`alloc_func`.
Only focus on cases with non-NULL `alloc_func` of
`hash_get()`.
Since `hash_get()` with non-NULL `alloc_func` parameter
shall not fail, just ignore the returned value of it.
The returned value must not be NULL.
So in this case, remove the unnecessary checking NULL
or not for the returned value and add `void` in front
of it.
Importantly, also *keep no change* for the two cases with
non-NULL `alloc_func` -
1) Use `assert(<returned_data> == <searching_data>)` to
ensure it is a created node, not a found node.
Refer to `isis_vertex_queue_insert()` of isisd, there
are many examples of this case in isid.
2) Use `<returned_data> != <searching_data>` to judge it
is a found node, then free <searching_data>.
Refer to `aspath_intern()` of bgpd, there are many
examples of this case in bgpd.
Here, <returned_data> is the returned value from `hash_get()`,
and <searching_data> is the data, which is to be put into
hash table.

If `hash_get()` returns NULL, the list created with
`list_new()` is not be freed.
Since `hash_get()` should not fail, we don't need
`list_delete()` and other boring `XFREE()`s for its
failure case.
Just ignore returning value of `hash_get()` in these
cases.

The "local_address" of bfd is only used in `show bfd peers brief`
for single hop sessions which are configured without "local address".
Since it is set by destination address of received packet, not
completely correct, so remove it.
