vrf_name_to_id(): remove
vrf_name_to_id() returned VRF_DEFAULT when the vrf name was
unknown, hiding errors. Per community recommendation, vrf_name_to_id()
is now removed and the few callers now use vrf_lookup_by_name()
directly.
ospfd: Memory Leak seen at show_ip_ospf_neighbor_all_common.
Problem Statement:
==================
Memory Leak seen at show_ip_ospf_neighbor_all_common (ospf_vty.c:4635)
RCA:
=================
In function show_ip_ospf_neighbor_all_common, one child json object is not
added to the parent child object when there is no nbma neighbor. Hence
the memory leak.
Fix:
=================
Add the child object to the parent json object.
This works for both tcp and ssh connections. In case the source
address is not available yet, the rpki retry interval will retry
in a defined amount of time.
Rtrlib library is the library in charge of the binding of the
tcp/ssh connection, and applies the getaddrinfo() and bind()
operations to the passed parameter bindaddr to the respective
tcp_config/ssh_config structures.

bgpd: fix bgp_get_bound_name to handle views better
The vrf socket code needs a interface/vrf name to be passed
in, in order for it to properly bind to the correct vrf.
In the case where bgp is using a view based instance
the bgp_get_bound_name should handle views better and
not return anything to be bound to.

bgpd: Do not randomly generate a vrf id for -Z
When FRR added the -Z parameter the bgp daemon was setting
a vrf identifier based upon a number starting at 1. This
caused issues when we upgraded the code to the outgoing
sockets to use vrf_bind always.
FRR should never just randomly select a vrf identifier.
Let's just use VRF_DEFAULT when we are in a -Z environment.
It's a safe bet.

ospfd: add dead-interval 40 if configured in show running
Problem Statement:
==================
When hello-interval is configured as 5, automatically dead interval becomes
4 times of hello i.e 20 seconds. But user wants the dead interval as
40 seconds and hello as 5 seconds. Therefore user configures it.
Now "ip ospf dead-interval 40" is not shown in "show running-config"
Therefore when user restarts the daemon, the dead interval goes back to
20 seconds and the neighbors are down.
Fix:
==================
If user configures dead-interval as 40, show it in show running config.

docker: build libyang2 along with FRR
Alpine images have been broken for some time because libyang2 is not
available in Alpine. This patch updates our Dockerfile to build a
libyang2 APK and install it into the image to satisfy FRR's libyang2
dependency.
Unfortunately, libyang2 erroneously includes an internal header from
glibc, making it dependent on glibc to build. FRR's official Docker
images are based on Alpine, which only offers musl libc. Until libyang2
fixes this problem, the libyang2 source that is installed in this image
is a patched version that is compatible with musl libc and not an
official version.

bgpd: Add `neighbor PEER link-bw-encoding-ieee`
This is to avoid breaking changes between existing deployments of
extended community for bandwidth encoding. By default FRR uses uint32
to encode bandwidth, which is not as the draft requires (IEEE floating-point).
This switch enables the required encoding per-peer.
The bandwidth of the link is expressed as 4
octets in IEEE floating point format, units being bytes (not bits!)
per second. It is carried in the Local Administrator subfield of the
Value Field.
Modified the zapi send receive of the c-bit to only
be under the HAVE_BFDD. If you are using ptm-bfd
then the decoder function still expects this to be
sent down. This commit puts this behavior back

As such, using prefix2str() (or the %pFX format specifier) isn't
correct when logging such routes.
This commit adds a few special cases here and there to handle
OSPF6_DEST_TYPE_ROUTER routes differently. It'd probably be a good
idea to add a helper function to handle all cases in a single place,
but that can be left for a second moment.
