Consistently omit /* FALLTHROUGH */ when we have a case statement that does
nothing. Since compilers don't warn about stacked case statements, and we were
inconsistent, resolve by removing extras.
This allows us to call it on a per-CPU basis and to warn if the details
are different across CPUs.
While here read the L1 I-Cache type and store this for use later by pmap.

Our iSCSI benchmarks on a large 80-core system show that previous limit
of 8 threads can be a bottleneck. At some points this change increases
write IOPS by as much as 50%. I am still not sure that so many threads
is really required, but we tested lower amounts and got no significant
benefits, while latencies were a bit worse, so decided to not diverge.

In r231852 I added in6_selectroute_fib() as a compat function with the
fibnum as an extra argument compared to in6_selectroute() to keep the
KPI stable.
Way too late retire this function again and add the fib to in6_selectroute()
which also only has a single consumer now and was an orphan function before.

Implement the equivalent of r347375 (IPv4) for the IPv6 output path.
In IPv6 we get passed a cached route (and inp) by udp6_output()
depending on whether we acquired a write lock on the INP.
In case we neither bind nor connect a first UDP packet would come in
with a cached route (wlocked) and all further packets would not.
In case we bind and do not connect we never write-lock the inp.
When we do not pass in a cached route, rather than providing the
storage for a route locally and pass it over the old lookup code
and down the stack, use the new route lookup KPI and acquire all
details we need to send the packet.
Compared to the IPv4 code the IPv6 code has a couple of possible
complications: given an option with a routing hdr/caching route there,
and path mtu (ro_pmtu) case which now equally has to deal with the
possibility of having a route which is NULL passed in, and the
fwd_tag in case a firewall changes the next hop (something to
factor out in the future).

In fib6_rte_to_nh_* when returning a link-local gateway address
currently we do clear the scope. That could be recovered using
the ifp returned as well, but the code in general seems to
expect a link-local address with scope embeedded as otherwise
the "dst" (gw) passed to the output routines will not include
scope and not send the packet out (the right interface).
Do not clear the scope when returning a link-local address and
allow packets to go out (the right interface).
Remove the (now) extra scope recovery in the IPv6 fast-fwd code.

We don't produce these anymore as of r356797, remove the remnant in
generate-ucl.sh that accounted for them. This isn't strictly necessary, but
future work is needed for the various packages that can be generated on a
lib build.
Namely, we may produce -development packages for private/internal libs that
should be installed but won't have the base FreeBSD-libfoo pkg to depend on
because it's internal (e.g. liby, libpmcstat, libifconfig) but we want the
headers installed. It may be a better move to just shove these into
-runtime-development instead, but if not then we've just simplified the
cases that need to take private/internal libs into account.
This allows libinput to disable touchpads when the lid is closed and
various desktop environments can show power-off dialogs when the power
button is pressed. While the latter is doable with devd a
cross-platform solution is nicer.
