Local ethernet segments are held in a protodown or error-disabled state
if access to the VxLAN overlay is not ready -
1. When FRR comes up the local-ESs/access-port are kept protodown
for the startup-delay duration. During this time the underlay and
EVPN routes via it are expected to converge.
2. When all the uplinks/core-links attached to the underlay go down
the access-ports are similarly protodowned.
The ES-bond protodown state is propagated to each ES-bond member
and programmed in the dataplane/kernel (per-bond-member).
Configuring uplinks -
vtysh -c "conf t" vtysh -c "interface swp4" vtysh -c "evpn mh uplink"

Add a command/functionality to only install proto-based nexthops.
That is nexthops owned/created by upper level protocols, not ones
implicitly created by zebra.
There are some scenarios where you would not want zebra to be
arbitrarily installing nexthop groups and but you still want
to use ones you have control over via lib/nexthop_group config
and an upper level protocol.

Implement the underlying zebra functionality to Add/Del an
internal zebra and kernel NHG.
These NHGs are managed by the upperlevel protocols that send them
down via zapi messaging.
They are not put into the overall zebra NHG hash table and only
put into to the ID table. Therefore, different protos cannot
and will not share NHGs.
The proto is also set appropriately when sent to the kernel.
Expand the separation of Zebra hashed/shared/created NHGs and
proto created and mangaged NHGs.
Signed-off-by: Stephen Worley <sworley@cumulusnetworks.com>
Remove the code for setting a NHG as unhashable. Originally
this was to prevent us from attempting to put duplicates from
the kernel in our hashtable.
Now I think its better to not use them in the hashtable at all
and only track them in the ID table. Routes will still be able
to use them if they specify the ID explicitly when sending Zebra
the route, but 'normal' routes we hash the nexthop group on
will not.

In all outputs (text and json): simplify and optimize the vrf name
display, use the vrf_id_to_name() handler.
Note: vrf_id_to_name() has a safeguard system that prevents from
crashing when the vrf cannot be found because it changed in some
(unexpected) manner, it returns "n/a".
Note: "vrf n/a" will now be displayed instead of "vrf UNKNOWN" in this
case, like in most other frr components.
This safeguard was missing for show ip route json, so this
optimization also fixes a potential crash.

Variable "show ip route" commands invoke the same helper
(do_show_ip_route), potentially several times.
When asking to dump a non-default vrf, all vrfs or all tables, the
output is messy, the header summarizing abbreviations is repeated
several times, excess line feeds appear, the default table of default
VRF is concatenated to the previous table output...
Normalize the output:
- whatever the case, display the common header at most once, if there
is at least an entry to dump.
- when using a "vrf all" or "table all" command, prepend a line with
the VRF and table (even for the default vrf or table).
- when dumping a specific vrf or table, prepend a line with the VRF
and table.

For the sake of Segment Routing (SR) and Traffic Engineering (TE)
Policies there's a need for additional infrastructure within zebra.
The infrastructure in this PR is supposed to manage such policies
in terms of installing binding SIDs and LSPs. Also it is capable of
managing MPLS labels using the label manager, keeping track of
nexthops (for resolving labels) and notifying interested parties about
changes of a policy/LSP state. Further it enables a route map mechanism
for BGP and SR-TE colors such that learned BGP routes can be mapped
onto SR-TE Policies.
This PR does not introduce any usable features by now, it is just
infrastructure for other upcoming PRs which will introduce 'pathd',
a new SR-TE daemon.

Today vtysh can show the ip/ip6 routes through several commands:
- show_route_cmd
- show_route_detail_cmd
- show_route_summary_cmd
- show_route_table_cmd
- show_route_table_vrf_cmd
- show_route_all_table_vrf_cmd
Each command has its own set of filter rules:
- show_route_cmd can filter by vrf, protocol, tag, ... but not by table
- show_route_table_cmd always filter by table
- show_route_table_vrf_cmd always filter by table and can filter by vrf
too
- show_route_all_table_vrf_cmd show all route in any table for a vrf (or
all)
To reduce the number of commands and provide a possibility to filter by
any key add possibility for the show_route_cmd to filter by table with a
specific value or all to get route in all tables.
Then the show_route_table_cmd, show_route_table_vrf_cmd and
show_route_all_table_vrf_cmd functions can be removed as they are covered
by the generic show_route_cmd function.
It is to be noted that when zebra is started by default, it is possible
to execute show ip route command with both vrf and table parameters,
whereas before the command was not displayed. This is due to the fact
that this combination is only permitted when zebra is launched with vrf
network namespace mode. There, if zebra is configured with vrf-lite
backend, then a vty error message informs the user that the combination
of both table and vrf is not possible.

We were creating `other` tables in rib_del(), vty commands, and
dataplane return callback via the zebra_vrf_table_with_table_id()
API.
Seperate the API into only a lookup, never create
and added another with `get` in the name (following the standard
we use in other table APIs).
Then changed the rib_del(), rib_find_rn_from_ctx(), and show route
summary vty command to use the lookup API instead.
This was found via a crash where two different vrfs though they owned
the table. On delete, one free'd all the nodes, and then the other tried
to use them. It required specific timing of a VRF existing, going away,
and coming back again to cause the crash.

command output too much, changing this to only give nhe_id
output when the user explicitly asks for it. Probably only
going to be used for debugging for now anyway.

When querying for detailed route information, show the nexthop
group id for its nh_hash_entry in the output before listing the
nexthops.

Add some more detailed output to `show nexthop-group`.
It closely resembles the output of `show ip routes`.

Switch the nhg_connected tree structures to use the new
RB tree API in `lib/typerb.h`. We were using the openbsd-tree
implementation before.

Create a nhg_depenents tree that will function as a way
to get back pointers for NHE's depending on it.
Abstract the RB nodes into nhg_connected for both depends and
dependents. This same struct is used for both.

Simplify the code for nexthop hash entry creation. I made nexthop
hash entry creation expect the nexthop group and depends to always
be allocated before lookup. Before, it was only allocated if it had
dependencies. I think it makes the code a bit more readable to go
ahead an allocate even for single nexthops as well.

Add an option to not specify the afi in the show nexthop-group
command so that it shows all nexthops, including groups. This is
how iproute2 does it. If the afi is given, it will only show single
nexthops since groups are AF_UNSPEC.

Add an interface pointer for an nexthop group hash entry
when we are getting a rib_add for a new route.
Also, add the interface index to the `show nexthop-group` command.

I do not believe we should be hashing based on AFI
in for our upper level nexthop group entries. These
should be ambiguous with regards to address families since
an ipv4 or ipv6 address can have the same interface
nexthop. This can be seen in NEXTHOP_TYPE_IFINDEX.

In the route_entry we are keeping a non pointer based
nexthop group, switch the code to use a pointer for all
operations here and ensure we create and delete the memory.

We need to track if a nexthop group is valid and installed,
so create some basic flags to track this.
