Each of Lua's major versions are incompatible with each other. Ubuntu,
at least, does not provide a single liblua.so or /usr/include/lua; all
SOs and headers are versioned, e.g. liblua5.3.so and
/usr/include/lua5.3. There's already an m4 macro in the GNU collection
to handle this situation, so let's use that.
This allows building with Lua enabled to work on platforms other than
Fedora.

* Turn the "instance" YANG presence-container into a YANG list keyed

* RIPng VRF instances can be configured even when the corresponding
VRF doesn't exist. And a RIPng VRF instance isn't deleted when
the corresponding VRF is deleted. For this to work, implement the
ripng_instance_enable() and ripng_instance_disable() functions
that are called to enable/disable RIPng routing instances when
necessary. A RIPng routing instance can be enabled only when the
corresponding VRF is enabled (this information comes from zebra
and depends on the underlying VRF backend). Routing instances are
stored in the new ripng_instances rb-tree (global variable).
* Add a vrf pointer to the ripng structure instead of storing vrf_id
only. This is much more convenient than using vrf_lookup_by_id()
every time we need to get the vrf pointer from the VRF ID. The
ripng->vrf pointer is updated whenever the VRF enable/disable hooks
are called.

The definition of the interface commands in vtysh.c were outdated.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.

* Remove the "no vrf NAME" definition from vtysh.c and expose the

DEFUN. This command doesn't change the vty node so there's no need to
special case it.

Currently, "vtysh -c" interface does not provide a logic to parse
commands ending with '?' character. In consequence, the following behavior
is observed:

% Unknown command.
With these changes, i'm extending FRR's parser to be able to handle
these commands, which allow a more friendly interaction with users
that rely on "vtysh -c" interface. The typical use-case here is for
scenarios in which the final users relie on external/their-own CLI and
require a friendly interface to FRR's vtysh cli.

When the user executes one of the commands 'no password' or 'no enable
password', a warning message gets shown to inform the user of the
security implications.
While the current implementation works, a warning message gets printed
once for each daemon, which can lead to seeing the same message many
times. This does not affect functionality, but looks like an error to
the user as it can be seen within issue #1432.
This commit only prints the warning message inside lib when vtysh
dispatch is not being used. Additionally, the warning message was copied
into the vtysh command handlers, so that they get printed exactly once.

The pull request #1545 from @donaldsharp introduced the command 'no
password' to remove an existing terminal connection password.
Additionally, warnings have been added to both 'no password' and 'no

It seems that this specific pull request was never merged against master
and got lost. This commit is a cherry-pick of d4961273cb with fixed
conflicts and updated documentation.
