David Lamparter 3ca60d00b1 *: add XREF_SETUP() to libraries and utilites
This is theoretically not needed if neither DEFUNs nor zlog_* calls are
used, except I'm about to turn it into a build error to catch the cases
where it _is_ necessary.  Which is libmgmt_be_nb.la in this case, where
it causes build failures on hppa.

Donald Sharp 26595e3162 zebra: Ensure proper decoding of netlink message
As part of the kernel netlink functionality, it is
possible that a bit of nested attributes can be
passed up.  This attribute has a type value which
is stored in the lower 8 bits and in the upper 8
bits are a couple control flags that can be used.
FRR can parse this data and then just throw away
the value unless we mask off the upper 8 bits.
Let's ensure that it can be properly parsed.

Donald Sharp cca4bb6527 zebra: Add ability to pretend routes are offloaded
In the fpm_listener add a -r option to allow for
routes to be notified back to zebra that the route
has been `offloaded` properly.

fpm_listener output:
New route 4.5.6.7/32, Prot: Static(196), Metric: 20, nhgid: 23
  Route Static(196) reflecting back
