Change the type of affinity leaf-list in frr-zebra to a leafref with
"require-instance" property set to true. This change tells libyang to
automatically check that affinity-map exists before usage and doesn't
allow it to be deleted if it's referenced. It allows us to remove all
the manual code that is doing the same thing.

When creating an initial tree trunk for oper data walk, if the xpath
represents a leaf, the leaf is created with an incorrect empty value.
If it doesn't actually exist in daemon's oper data, its value is not
overwritten later and an empty value is returned in the result.
For example, when requesting
`/frr-interface:lib/interface[name='eth0']/description`, the result is:
```
{
"frr-interface:lib": {
"interface": [
{
"name": "eth0",
"description": ""
}
]
}
}
```
instead of an empty JSON that it should be.

Replace operation removes the current data node configuration and sets
the provided value. As current northbound code works only with one
xpath at a time, the operation only makes sense to clear the config of
a container without deleting it itself. However, the next step is to
allow passing JSON-encoded complex values to northbound operations which
will make replace operation much more useful.

Currently, there's a single operation type which doesn't return error

Currently, nb_operation enum means two different things - edit operation
type (frontend part), and callback type (backend part). These types
overlap, but they are not identical. We need to add more operation
types to support NETCONF/RESTCONF integration, so it's better to have
separate enums to identify different entities.

The maximum number of file descriptors in an fd set is limited by
FD_SETSIZE. This limitation is important because the libc macros
FD_SET(), FD_CLR() and FD_ISSET() will invoke a sigabort if the size of
the fd set given to them is above FD_SETSIZE.
We ran into such a sigabort with bgpd because snmp can return an fd set
of size higher than FD_SETSIZE when calling snmp_select_info(). An
unfortunate FD_ISSET() call later causes the following abort:
Received signal 6 at 1701115534 (si_addr 0xb94, PC 0x7ff289a16a7c); aborting...

Also, the following error is logged by snmp just before the abort:
snmp[err]: Use snmp_sess_select_info2() for processing large file descriptors
snmp uses a custom struct netsnmp_large_fd_set to work above the limit
imposed by FD_SETSIZE. It is noteworthy that, when calling
snmp_select_info() instead of snmp_select_info2(), snmp uses the same
code working with its custom, large structs, and copy/paste the result
to a regular, libc compatible fd_set. So there should be no downside
working with snmp_select_info2() instead of snmp_select_info().
Replace every use of the libc file descriptors sets by snmp's extended
file descriptors sets in agentx to acommodate for the high number of
file descriptors that can come out of snmp. This should prevent the
abort seen above.

- Install a new CLI command `source-address` under the
`SRV6_ENCAP_NODE` node. This command is used to configure the source
address of the outer encapsulating IPv6 header.
- Install a new CLI command `no source-address` under the

source address of the outer encapsulating IPv6 header and restore the
default source address.

Batch IDs are only used to verify that all messages were received and
processed by a backend. It's not necessary to do that as we use reliable
stream transport - messages can't be dropped or received out of order.
This commit also fixes possible race condition that can happen if
one backend process messages slower than other backends.

Keep track of the last starting spot of where fd's were
being handled for read operations. Modify the io read
handler to cycle through the list of fd's that need
to be handled such that fd's at the front do not take
precedence for being handled all the time.

Currently when io is ready inside of the event system
the first FD received is always preferred as the ones
that are handled first. This leads to results where
events associated with these first FD's are always handled
first.
In anticipation of a change to make this more fair
let's abstract the function handler.

As with "prefixptr"/"prefixconstptr", this allows function prototypes to
say "just give me any sockaddr" typing-wise, without having the compiler
complain that a "struct sockaddr_in" is not a "struct sockaddr".

This was true when we had only a CLI for configuration. Now mgmtd has a
public frontend interface that can be used by external applications, and
they can send invalid requests that lead to errors.
This is still true for CLI though, so the same comment still stays in
`nb_cli_apply_changes_internal`.

The routing table numbers are specific to linux builds, and the
RT_TABLE_xxx are usually defined in linux headers. The bsd builds
do not benefit from this definition: some RT_TABLE_xxx defines
are missing for those builds.

Add a new kind of redistributed route that helps to import entries
that are not copied in the default routing table. Contrary to the
'redistribute table' feature, the entries are directly obtained from
the zebra appropriate routing table.
The 'table-direct' naming expresses the direct redistribution of
the routes, without having to copy the route entries in the default
routing table.
The distance value for this route is 14. Such route entries will
be prioritary compared to 'table' and 'ebgp' route entries type.
