The frr-interface YANG module models interfaces using a YANG list keyed
by the interface name and the interface VRF. Interfaces can't be keyed
only by their name since interface names might not be globally unique
when the netns VRF backend is in use. When using the VRF-Lite backend,
however, interface names *must* be globally unique. In this case, we need
to validate the uniqueness of interface names inside the appropriate
northbound callback since this constraint can't be expressed in the
YANG language. We must also ensure that only inactive interfaces can be
removed, among other things we need to validate in the northbound layer.

Introduce frr-interface.yang, which defines a model for managing FRR
interfaces.
Update the 'frr_yang_module_info' array of all daemons that will
implement this module.
Add automatically generated stub callbacks in if.c. These callbacks will
be implemented in the following commit.

This plugin leverages the northbound API to integrate FRR with Sysrepo,
a YANG-based configuration and operational state data store.
The plugin is linked to the libsysrepo library and communicates with
the sysrepod daemon using GPB (Google Protocol Buffers) over AF_UNIX
sockets. The integration consists mostly of glue code that calls the
appropriate FRR northbound callbacks in response to events triggered
by the sysrepod daemon (e.g. request to change the configuration or to
fetch operational data).
To build the sysrepo plugin, provide the --enable-sysrepo option to the
configure script while building FRR (the libsysrepo library needs to be
installed in the system).
When installed, the sysrepo plugin will be available for all FRR daemons
and can be loaded using the -M (or --module) command line option.
Example: bgpd -M sysrepo.

This plugin leverages the northbound API to integrate FRR with the ConfD
management agent.
The plugin is linked to the libconfd library and communicates with the
confd daemon using local TCP sockets. The integration consists mostly
of glue code that calls the appropriate FRR northbound callbacks in
response to events triggered by the confd daemon (e.g. request to change
the configuration or to fetch operational data).
By integrating FRR with the libconfd library, FRR can be managed using
all northbound interfaces provided by ConfD, including NETCONF, RESTCONF
and their Web API.
The ConfD CDB API is used to handle configuration changes and the ConfD
Data Provider API is used to provide operational data, process RPCs and
send notifications. Support for configuration management using the ConfD
Data Provider API is not available at this point.
The ConfD optional 'get_object()' and 'get_next_object()' callbacks were
implemented for optimal performance when fetching operational data.
This plugins requires ConfD 6.5 or later since it uses the new leaf-list
API introduced in ConfD 6.5.
To install the plugin, the --enable-confd option should be given to the
configure script, specifying the location where ConfD is installed.
Example: ./configure --enable-confd=/root/confd-6.6
When installed, the confd plugin will be available for all FRR daemons
and can be loaded using the -M (or --module) command line option.
Example: zebra -M confd.

FRR_DAEMON_INFO should now contain an array of 'frr_yang_module_info'
structures describing the YANG modules implemented by the daemon.
This array will be used by frr_init() function to load all YANG modules
and initialize the northbound callbacks during the daemon initialization.

For some reason, automake was "randomizing" the order of these few lines
in the generated output Makefile.in.
I have absolutely no clue what's going on, but it's the only thing
preventing me from building reproducible source tarballs (i.e.
bit-exactly identical), so... just slightly "rephrase" this.
Should behave exactly the same as before.

The `struct zebra_ns` data structure is being used
for both router information as well as support for
the vrf backend( as appropriate ). This is a confusing
state. Start the movement of `struct zebra_ns` into
2 things `struct zebra_router` and `struct zebra_ns`.
In this new regime `struct zebra_router` is purely
for handling data about the router. It has no knowledge
of the underlying representation of the Data Plane.
`struct zebra_ns` becomes a linux specific bit of code
that allows us to handle the vrf backend and is allowed
to have knowledge about underlying data plane constructs.
When someone implements a *bsd backend the zebra_vrf data
structure will need to be abstracted to take advantage of this
instead of relying on zebra_ns.

When there is a stream of events coming in, where IS-IS learns
about a lot of updates, IS-IS would regenerate its LSPs before
the updates have been processed completely.
This causes suboptimal convergence because the intermediate state
will be flooded. Only after the configured `lsp_gen_interval`, a
new update with the correct and final state will be generated.
Resolve this by holding off LSP generation while there are still
events coming in.

community_free, lcommunity_free and ecommunity_free are similar type of functions. Most of the places, these three are called together. The signature of community_free is different from other two functions. Modified the community_free API signature to align with other two functions to avoid any confusion. There is no functionality impact with this and this is just to avoid any confusion.
