When we add / remove a nexthop that we need to track,
keep track of the number of times we have done this
for each nexthop. Consequently keep track of the
number of available nexthops, so that we can
just install new routes when we get one
that uses a pre-existing nexthop. Deletion of
nexthops is done on refcount going to 0.
Removal of routes is handled elsewhere for removal.

this function had to be used only inside zebra ( this was written in the
header vrf.h). To keep the functionality, a more generic API is used.

Aded a check to ensure that if_is_vrf() is not called on a NULL if pointer.
Incidentally this was causing PR #2805 to fail.

Move the call to the static_install_route to inside
of the loop, since we have changed the behavior of
how we send down routes to zebra a bit.

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.

When the user is not using the integrated config and
has upgraded to a version of FRR with staticd, that
probably means that static routes are stored in zebra.conf.
Take advantage of the backup backup config option and read
those in.

This is the start of separating out the static
handling code from zebra -> staticd. This will
help simplify the zebra code and isolate static
route handling to it's own code base.
