Since it is possible to be asking for label data before the zclient has
been connected, let's just return -1 in the case where zclient is not
initialized yet either, since this is effectively the same thing as
the sock being < 0.

feff426771 lib: Add ifindex to SRv6 SID context
The uA behavior is associated with an interface and the IP address of
the nexthop. However, the current SID context data structure only
includes the IP address. It lacks the interface.

This commit extends the SID context data structure by adding the
ifindex. This extension allows daemons to allocate uA SIDs with
the required interface and IP address.

This also fixes a bug with specific (position specified) queries on keyless
lists. If the `get_next` callback is using the parent entry it will probably
crash as the code is passing the list_entry as both parent and child in the
specific lookup case.

There may currently be no code that uses the parent entry if the child entry is
non-NULL, though.

lib,zebra: Allow class E prefixes in RIB
Changes allow ipv4 class E addresses and prefixes in the 240.0.0.0/4
range to be configured on interfaces, imported from the kernel routing
table and redistributed as connected routes in zebra by default.

Changes also fix routes with class E prefixes in kernel routing table
getting rejected by zebra during early daemon startup.

Drivin this change in default behavior are cloud providers (with
customers still using obsolete ipv4 protocol, i.e. Azure, AWS) running
out of ip space and abusing class E for addressing instances (announced
via BGP) over tunneling connections back to customers on premise
infrastructure.

cae176e10a lib: fix use after free in clear event cpu
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.

3671ce36fd staticd: fix botched staticd YANG for dst-src
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'`.
