ctx status, dpending on the operation performed.

for install/uninstall into the kernel.

Add a function for installing Nexthop Group hash entires into
the kernel. It sends the entry to the dataplane and does any
post-processing immediately after that.

Added a NEXTHOP_GROUP_QUEUED flag to the nexthop
group hash entry struct. This indicates when we have
sent it to be installed to the kernel and are waiting
for the dataplane provider to process it.

Add the functionality to parse new nexthop group messages
from the kernel and insert them into the appropriate hash
tables. Parsing is done at startup between interface and
interface address lookup. Add functionality to parse
changes to nexthops we already have. Add functionality
to parse delete nexthop messages from the kernel and
remove them from our table.

I do not believe we should be hashing based on AFI
in for our upper level nexthop group entries. These
should be ambiguous with regards to address families since
an ipv4 or ipv6 address can have the same interface
nexthop. This can be seen in NEXTHOP_TYPE_IFINDEX.

The messages we get from the kernel come with ids only
for groups, so lets index with those as well. Also adding
a helper function for lookup and get with the two different
tables.

Add some code to allow us to do lookups and releases of
nexthop groups from zebra. At this point we do not do anything
with it.

We need to track if a nexthop group is valid and installed,
so create some basic flags to track this.

This commit does nothing more than just create a hash structure
that we will use to track nexthop groups.

Since these functions are not really rib processing problems
let's move them to zebra_nhg.c which is meant for processing of
nexthop groups.
