lib, ripngd, zebra: Remove pre-solaris 9 special cased code
The CMSG_FIRSTHDR was broken on solaris pre version 9. Version 9
was released in May of 2002 and EOL'ed in 2014. Version 8 EOL'ed
in 2012. Remove special case code for a little used platform
that has not seen the light of day in a very long time.

bfdd: Fix `don't assign to value to ourself` compiler warning
We were attempting to get around a unused value by setting
a variable to itself, but it runs afoul of a different
compiler and a message about not setting a variable to
itself. So let's mark the ttl value as unused.

bgpd: Always show CIDR mask when displaying routes
Classful networking has been obsolete for ages and there is currently an
inconsistency between `show ip route` and `show bgp`, where the first
one always displays the CIDR mask while the second one hides classful
network masks.
This commit adjusts the behavior of `show bgp` to always show the CIDR
mask for a route, even when it is classful.
lib, vtysh: fix inconsistent interface commands in vtysh
The definition of the interface commands in vtysh.c were outdated.
Currently, all daemons that call if_cmd_init() will have the "no interface
IFNAME" command and the "[no] description" commands as well, so there's
no need to define exceptions for these commands anymore.
To fix this, make extract.pl parse the if.c file so that vtysh can get the
interface commands from there automatically. Only the "interface IFNAME
[vrf NAME]" must be kept in vtysh.c because it changes the vty node and
thus needs special treatment.
Finally, make pimd and pbrd display interface descriptions on "sh run"
when they are configured.
lib, vtysh: fix inconsistent VRF commands in vtysh
* Only zebra and pimd call vrf_cmd_init(), so these are the only daemons
that should receive VRF commands from vtysh;
* "netns NAME" and "no netns NAME" are available only in zebra, write
custom DEFSHs in vtysh to make it aware of that;
* Remove the "no vrf NAME" definition from vtysh.c and expose the
original command to vtysh by converting the DEFUN_NOSH to a simple
DEFUN. This command doesn't change the vty node so there's no need to
special case it.
We must hide only "pseudowire IFNAME" from vtysh, the "no" form of the
command should be made available to the extract.pl script. Split the
command into two to fix this problem.
All ldpd commands were written using DEFPY except the ones that needed
to be ignored by vtysh, in which case we were using DEFUN_NOSH. Now that
DEFPY_NOSH is available, convert the remaining commands for consistency
and to simplify the code a little bit.
The correction in commit 7edb6aa (PR #2502) was wrong, as it is was not
taking in consideration the unlock counter. Thanks to @eqvinox for noticing
it.

*: ALLOC calls cannot fail
There is no need to check for failure of a ALLOC call
as that any failure to do so will result in a assert
happening. So we can safely remove all of this code.

tools: correct frr-reload.py handling of bgp vni/exit-vni config
Problem reported that when a peer-group was added in certain
configurations, it would be rejected because of the order of the

was handling the sub-sub-context of the vni under the address-family

On `zebra` / `bfdd` shutdown we now clean up all client data to avoid
