If the admin creates more CTL ports than kern.cam.ctl.max_ports, then
adding some will fail. If he then removes some ports and does
"service ctld reload", he would expect that the new ports would get
added in the newly-freed port space. But they don't, because ctld
assigned them port numbers during their first creation attempts.
Fix this bug by removing newly created ports from ctld's internal list
if the kernel rejects them for any reason. That way, a subsequent
config reload will attempt to add them again, possibly with new port
numbers.

fetchmissingdists naturally sets BSDINSTALL_DISTDIR to a directory in
the new filesystem that it can write fetched distfiles to. As a result,
BSDINSTALL_DISTSITE was incorrectly set to the scratch space on /mnt for
the call to distfetch when grabbing local distfiles, and it would
subsequently fail.
Switch to using the copy of BSDINSTALL_DISTDIR that we stashed off
coming into fetchmissingdists; this one is in-fact set to the path where
the local distfiles are stored.
Patch suggested by jrtc27.

During discussions with someone that was doing NFS-over-TLS
development for Solaris, we had a concern that the server might
become overloaded after rebooting, due to a large number of
TLS handshake requests from clients.
To alleviate this potential problem, this patch modifies rpc.tlsservd
so that it supports the "-N/--numdaemons" command line option,
which specifies that up to RPCTLS_SRV_MAXNPROCS (currently defined
as 16 in the patch) may be started.
When there are multiple daemons, one is selected by the patched kernel
in a round-robin fashion, to serve a TLS handshake request.
The man page update will be done in a future commit.

Whilst reboot(8) will block whilst it runs, shutdown(8) does not,
daemonizing instead. This means that we must wait after running it,
otherwise we will exit and cause the system to attempt to go multi-user
in parallel with the shutdown daemon killing init. With the new
multi-console support in the installer, runconsoles will immediately
kill this daemon, racing with the daemon being able to signal init as
desired, and I have seen this race be lost in QEMU with a single CPU. In
the past this wasn't such an issue, since shutdown's daemon puts itself
in a new session group immediately after fork (and the parent doesn't
wait until that has happened, so whilst there's technically a race
condition in there where it could receive a SIGHUP from the death of the
parent's session leader, in practice this is very unlikely to be hit.
This means that the only consequence of this oversight before was that
you might get the beginnings of more console output on the way to
multi-user and thus the console would look a little confusing.

Whilst febca0e643 added -N for both build and extract, it only fully
worked for extract; build would perform the actual tree build with
-DNO_ROOT and construct the intended METALOG, but the subsequent tarball
creation did not take this into account and just tarred up the the
directory as-is rather than using the METALOG. This resulted in the
permissions and ownership not being correct, as well as there being a
stray METALOG file in the tarball's root.

Currently the installer is only started on the primary ("high level")
console. For systems where this is the video console and serial consoles
aren't of interest, and headless systems with just a serial console,
this works just fine, but for systems where both video and serial
consoles are present and meaningful this requires the user to select the
right primary console in loader, with the poor user experience of the
system appearing to hang if they leave the wrong one selected. This
notably differs from our multi-user behaviour of spawning getty on every
console, where the only issue with selecting the wrong primary console
is a quieter boot process until the login prompt appears (or the system
crashes).
Instead, use the newly-added runconsoles helper to run the installer on
every console (except for ttyv*, where only ttyv0 will be used). For
interactive installations, any of the consoles can be used, though only
one should be used at a time as no effort is made to avoid multiple
installations running at the same time clobbering each other. If the
Live CD option is selected, the other installers (which should, if the
user is well-behaved, be sitting at the welcome screen) will be killed.
If an automated install is in use, the primary console will be used to
display its output, and the others will direct the user to the primary
console.
