The backtrace functionality has been abstracted over
to zlog_backtrace(). Now that every place uses this
move the inclusion for HAVE_GLIBC_BACKTRACE into
the appropriate files instead of having everyone
pay for this costly include.

The rfapi code was not using the zlog_backtrace()
functionality. Let's just convert over to using
the proper functionality that we have built in now.

The only 2 places sendmmsg is used is in zlog_5424.c
and zlog_live.c. Why is the rest of the entire system
paying for this compilation?

Heard back from libyang folks that this is not something they consider part of
the API and/or are going to guarantee. So we cannot count on it. Expect keys at
any location on the child sibling list.

When bgp update is received for EVPN prefix
where for an existing path's nexthop becomes unreachable,
the path is marked as not VALID but the routes
were not unimported from tenant vrfs, which lead to
stale unicast route(s) and nexthop(s).
In Multipath scenario only a specific path may have marked as
not VALID, then specific path info for the EVPN prefix required to be
unimported from tenant vrf.

Allow user to leave keys off of a list entry node at the end of the xpath. This
will return all list entries. Previously there was no way to just get the list
entries. One had to leave off the last list entry node which would then return
all list nodes as well as all the siblings at the same level.
