Apparently Automake has some undocumented logic somewhere that makes it
so any Makefile generated from an Automake Makefile.am is removed from
its secret list of things to delete that it deletes when performing a
recursive distclean before actually performing the recursive distclean
and since the secret list is automatically generated from the list of
things that Autoconf should generate in configure.ac we can't remove the
Makefile from that list or it will break Automake's list of things to
automatically generate that it generates from Autoconf's list of things
to automatically generate.
Thus, to prevent Automake from deleting Makefiles and then immediately
trying to use the Makefiles it just deleted to delete said Makefiles, we
must remove ourselves from the secret list, which is accomplished by
changing the file extension to '.am' instead of '.in'.

Setup the buf used for extra data passed into kernel such
that we are cleaning it out before writing data to it,
so we can avoid writing uninited data.

Use brouter table to fetch nexthops for
asbr prefix (external) routes.
Change adv. router of the router's path once
the DB/FIB is updated with effective nexthops.
Cleanup of nexthop update when route's adv
router changes cost.
Ticket:CM-16139
Testing Done:
Tested ASBR external routes in CLOS topology with
multiple paths asbr originator at tor to spine.
Validated external route's nexthop within
area and inter area.

Add the documentation for match source-instance.
I also noticed that 'match source-protocol' was missing
add that in too.

Add to zebra route-maps the ability to match on a source-instance
route-map FOO deny 55
match source-instance 5
route-map FOO permit 60
ip protocol any route-map FOO
This will match any protocol route installation with a source-instance of 5.

The neighbor host_list is expensive as well. Modify
the code to take advantage of a rb_tree as well.

We are going to modify more host_list's to host_rb's
so let's rename some functions to take advantage of
what is there.

The host_list when we attempt to use it at scale, ends
up spending a non-trivial amount of time finding and
sorting entries for the host list. Convert to a rb tree.

Kernel 2.2 was released in 1999, I'm pretty sure everybody has it by
now. Plus these links don't even exist anymore.

While we have docs on various pieces of the build system we don't have
any docs on how to actually get FRR running once it's installed, nor do
we have comprehensive documentation on the basic procedure for building
from source. This patch remedies both of those.
Also updated the services list in the docs and removed the SERVICES file
from the project root.

The bgp_info_extra_get call gets the extra pointer, which
is also needed for the setlabels() call, so move the call
to above the setlabels.
Also remove an unnecessary test of a pointer since we
have already dereferenced it by the time we are testing
for it's existence.

Modify the nht code to use a bit bigger buffer.

The required packages list should be easier to parse. Updated the style so it's more similar to the ``./configure`` style later in the document.

While the current implementation does pay attention to the AF
(inet/inet6) when comparing the IPv4/v6 address against an address-list
/ prefix-list inside a route-map, the AF check is being done rather
late, which leads to CPU cycles being wasted due to unnecessary list
lookups / address matching.
This commit checks the address family of a prefix right inside the
`route_match_ip(v6)_` functions before looking up any address- and/or
prefix-list, which should improve performance.
