It's time to say good bye to libyang 0.16.105. The recently
released libyang 1.0.184 includes numerous bug fixes and performance
improvements that we need.
Despite the major version bump from 0.x to 1.x, the libyang API is
the same except for a single backward-incompatible change in the
user types interface (which we're currently not using). Hence no
code changes were necessary to adapt FRR to libyang 1.x.
This commit also reintroduces some leafrefs that needed to be
removed from our YANG modules due to a bug that was present on
libyang 0.16.105.

Signed-off-by: Donald Sharp sharpd@cumulusnetworks.com>
Yang constraints enforced by the northbound callbacks require that
the maximum lifetime be >= than (refresh interval + 300). When we are
moving from one config to another through frr-reload.py, we issue
a number of vtysh -c commands ('no lsp-refresh-interval level-1 500',
'no max-lsp-lifetime level-1 1000'), which reset these parameters to their
default values, respectively 900 and 1200. Depending on the actual
values in the current config, the order in which these commands are sent
might be the wrong one, in that we hit an invalid intermediate state and
make vtysh (and by extension frr-reload.py) return an error.
As a workaround, let's add a one-liner command that sets all these
inter-related parameters in one go, and make isisd display them as a
single line too, so that the diff will be computed as a single command.
The old individual commands are kept to ensure backwards compatibility.

Currently isisd has this strange (legacy) behavior where the
first area is created by default with level-1-2, while every
other subsequent area uses the default defined in the yang model,
which is level-1. This is a source of confusion when trying to
configure the daemon programatically, either with frr-reload
or using the transactional cli. Given how rare having multiple
IS-IS instances is anyway, the easiest solution is to remove
this behavior and default to level-1-2 for every area.
Note that this does not affect fabricd, which continues using
exclusively level-2-only areas.

our libyang custom user types temporarily so that FRR can work

isisd has both a circ_type and a circ_type_config variable to track
the network tpye of an interface. The former has no default, but the
latter defaults to broadcast. Adding that default makes sure that the
yang leaf won't be deleted, which is something that would not make

YANG allows lists without keys for operational data, in which case
the list elements are uniquely identified using a positional index
(starting from one).
This commit does the following:
* Remove the need to implement the 'get_keys' and 'lookup_entry'
callbacks for keyless lists.
* Extend nb_oper_data_iter_list() so that it special-cases keyless
lists appropriately. Since both the CLI and the sysrepo plugin
use nb_oper_data_iterate() to fetch operational data, both these
northbound clients automatically gain the ability to understand
keyless lists without additional changes.
* Extend the confd plugin to special-case keyless lists as well. This
was a bit painful to implement given ConfD's clumsy API, but
keyless lists should work ok now.
* Update the "test_oper_data" unit test to test keyless YANG lists in
addition to regular lists.

The northbound infrastructure for operational data was subpar compared
to the infrastructure for configuration data. This commit addresses most
of the existing problems, making it possible to write operational-data
callbacks for more complex YANG models.
Summary of the changes:
* Add support for nested YANG lists.
* Add support for leaf-lists.
* Add support for leafs of type "empty".
* Introduce the "show yang operational-data XPATH" command, and write an
unit test for it. The main purpose of this command is to make it
easier to test the operational-data northbound callbacks.
* Introduce the nb_oper_data_iterate() function, that can be used
to iterate over operational data. Make the CLI and sysrepo use this
function.
* Since ConfD has a very peculiar API, it can't reuse the
nb_oper_data_iterate() like the other northbound clients. In this
case, adapt the existing ConfD callbacks to support the new features
(and make some performance improvements in the process).
