Make it consistent and call it `event` when formatting something to
display. Much less confusing for some user seeing it too, since threads
aren't involved.

Refactor the "timer getting executed too late" warning:
- warning threshold is now adjustable
- check is performed when event actually executes, rather than when it's
thrown on ready list
- ignore_late_timer replaced with threshold = 0
- system load averages printed in log message
- warning ratelimited to once per 10s rather than once per poll()

The `show ipv6 route json` command displays the IPv6 routing table in
JSON format, including SRv6 SIDs. For each SRv6 SID, it provides
behavior and SID attributes. However, it does not include the SID
structure.
This commit adds the SID structure to the SRv6 SID JSON output.

Blocking all signals on non-main threads is not the way to go, at least
the handlers for SIGSEGV, SIGBUS, SIGILL, SIGABRT and SIGFPE need to run
so we get backtraces. Otherwise the process just exits.

The seg6local route dumped by 'show ipv6 route' makes think that the USP
flavor is supported, whereas it is not the case. This information is a
context information, and for End, the context information should be
empty.
> # show ipv6 route
> [..]
> I>* fc00:0:4::/128 [115/0] is directly connected, sr0, seg6local End USP, weight 1, 00:49:01
Fix this by suppressing the USP information from the output.

When called without caps/privs, just return from "change_caps"
instead of exiting - it's possible that a process may not need
privs, but a lib (for example) may use the api.

We were hashing 4 bytes of the address. Even for IPv6 addresses.
Oops.
The reason this was done was to try to make it faster, but made a
complex maze out of everything. Time for a refactor.

When reading in a nexthop from ZAPI, only set the fields that actually
have meaning. While it shouldn't happen to begin with, we can otherwise
carry padding garbage into the unused leftover union bytes.

Freeing any item here means freeing someone's `event->hist`, leaving a
dangling pointer there. Which will immediately be written to because
we're executing in a CLI function under the `vty_read` event, whose
`event->hist` is then updated.
Deallocating `event->hist` anywhere other than shutting down the whole
event loop is a bad idea to begin with, just zero out the stats instead.

When a daemon wants to know about its routes, make it possible to have
that work for dst-src routes.

The staticd YANG conversion completely f*cked up dst-src routes.
Stupidly enough, the correct thing is much simpler as seen by the amount
of deletes in this commit.
This does, unfortunately, involve a rather annoying YANG edge case with
what should reasonably be an optional leaf as part of a list key, which
is not possible. It uses `::/0` as unconditional filler instead, since
that is semantically correct.
The `test_yang_mgmt` topotest needed to be adjusted after this to add
`src-prefix='::/0'`.

sbfd will use bfdname for key hash, We introduced a bfd-name for every sbfd session, normal BFD sessions can leave it as NULL.
A unique bfd-name can be used to identify a sbfd session quickly. This is quite useful in our Srv6 deployment for path protection case.
For example, if use the sbfd session to protect the SRv6 path A-B-D, we would assign the name 'path-a-b-d' or 'a-b-d' to the session.

The previous use of `lyd_new_path()` returns the first node created, rather
than the xpath target node. The code is lucky in the sense that it is
normally only creating a single node rather than a branch. Fix this to
use `lyd_new_path2()` which returns the target node to actually implement
the semantics expected by callers of `dnode_create()` (i.e., returning the
newly created target node).

This commit moves DEFAULT_SRV6_IFNAME from isis_srv6.h to srv6.h

Current -n option is only for zebra and mgmtd. All other daemons receive
the VRF backend configuration from zebra upon connection to it. This
leads to a potential race condition - daemons need to know the backend
before they start reading their config, but they can be not connected to
zebra yet at this point. As the VRF backend cannot change during runtime,
let's introduce a new global -w option for setting netns backend, to
make sure that all daemons know their VRF backend immediately after
start.
The reason for introducing a new option instead of making -n global is
that ospfd already uses -n for another purposes.

vrf->ns_ctxt is only ever used in zebra, so move its initialization to
zebra's callback. Ideally this pointer shouldn't even be a part of
library's vrf struct, and moved to zebra-specific struct, but this is
the first step.
