88a9001659 staticd: Fix recursive routes for certain types of nexthops
Existing NEXTHOP_TYPE_IPV4_IFINDEX and NEXTHOP_TYPE_IPV6_IFINDEX
routes allow recursion, but were broken when the route happened
to recursively resolve and the resolution nexthop changed.

This commit fixes this issue.  Please note that this issue was
in pre-move of static route handling to it's own daemon as well.
This was some easy low-hanging fruit, so to speak.

2551bd4c89 bgpd: route detail output local pref display
Avoid displaying default configured local preference as
part of bgp route's detail output.
Local preference is for iBGP learnt route's. The value could be
default (100) or configured value (via routemap or local pref config cmd).
show bgp afi safi (brief output) does not display,
if the local pref attribute is not set.
Similarly, show bgp afi safi detail route output should display
if the the attribute is set, and should not display configured value.
This way both output would be consistent.
The configured local preference can be seen via running-config.

239b37bb3c bgpd: Notice when we unlock if we should NULL pointer
The bi->net pointer that is being unlocked had a commit
that removed the `bi->net = NULL;` recently.  This code
was preventing a use after free crash being experienced
in other code paths.  While commit 37e679629f was fixing
a different code path crash.

Make the parent->net pointer aware it may be locked/freed
from multiple places and to not NULL the pointer to it
unless we have actually freed the data.

e6a0e0d141 zebra: Check for netlink message next fault
NLMSG_NEXT decrements the buffer length (status) by
the header msg length (nlmsg_len) everytime its called.
If nlmsg_len isn't accurate and set to be larger than
what it should represent, it will cause status to
decrement passed 0. This makes NLMSG_NEXT return a
pointer that references an inaccessible address.
When that is passed to NLMSG_OK, it segfaults.

Add a check to verify that there is still something to read
before we try to.
