Dell-branded Intel P4600 NVMe drives benefit from NVMe 1.3's NOIOB

themselves as benefiting from this...
This changes adds P4600s to the existing list of old drives which

WITH_SSP_PORTS was relevant in the FreeBSD 9 and FreeBSD 10 days.
Nowadays, -fstack-protector is set by default. Relevant knobs and variables
are documented in ports/Mk/bsd.port.mk.
WITH_GHOSTSCRIPT_VER was part of USE_GHOSTSCRIPT, which is deprecated.

In r342771, I introduced a regression in Power by abusing the platform
smp_topo() method as a shortcut for providing the MI information needed for
the stated sysctls. The smp_topo() method was already called later by
sched_ule (under the name cpu_topo()), and initializes a static array of
scheduler topology information. I had skimmed the smp_topo_foo() functions
and assumed they were idempotent; empirically, they are not (or at least,
detect re-initialization and panic).
Do the cleaner thing I should have done in the first place and add a
platform method specifically for core- and thread-count probing.

Previously, the following sequence of events was feasible under some
circumstance:
bectl create test
bectl activate test
# the test BE dataset gets promoted and set as bootfs
bectl destroy test
I was unable to reproduce the destroy succeeding, but we should be rejecting
this before it even gets to libzfs because it would leave the system in an
inconsistent state. Forcing the user to be explicit as to which environment
should be activated instead is much better.

when devd(8) is running (used by default).
Based on patch from PR; other changes on top of it:
- '-f' (force) -> '-s' (source) parameter renaming;
- allow 'apm' -> 'devd' transition when '-s devd' is set
(if APM is enabled);
- man page update.

Originally intended as 'in case in needs to be re-invoked', but it was later

Some rc scripts in ports (e.g. uwsgi, apache, openvpn) allow for
'application profiles' that usually require the rc script to be invoked
again for each active profile. Because there's no consistent way to
determine the path because it differs between manual/service(8) invocations
and /etc/rc invocations, this leads to patterns like these:
- www/uwsgi hardcodes the script path
- security/openvpn guesses either $_file or $0 based on $0 = /etc/rc
Instead of forcing rc scripts to guess, provide an rc_service variable to
the scripts that gets set appropriately both for direct execution or when a
script is being executed via run_rc_script (e.g. /etc/rc).
This is our analog of an OpenRC variable with the same name, different case
(RC_SERVICE).

These programs parse ND6 Router Advertisement messages; rtsold(8) has
required an SA, SA-14:20.rtsold, for a bug in this code. Thus, they
are good candidates for sandboxing.
The approach taken is to run the main executable in capability mode
and use Casper services to provide functionality that cannot be
implemented within the sandbox. In particular, several custom services
were required.
- A Casper service is used to send Router Solicitation messages on a
raw ICMP6 socket. Initially I took the approach of creating a
socket for each interface upon startup, and connect(2)ing it to
the all-routers multicast group for the interface. This permits
the use of sendmsg(2) in capability mode, but only works if the
interface's link is up when rtsol(d) starts. So, instead, the
rtsold.sendmsg service is used to transmit RS messages on behalf
of the main process. One could alternately define a service
which simply creates and connects a socket for each destination
address, and returns the socket to the sandboxed process. However,
to implement rtsold's -m option we also need to read the ND6 default
router list, and this cannot be done in capability mode.
- rtsold may execute resolvconf(8) in response to RDNSS and DNSSL
options in received RA messages. A Casper service is used to
fork and exec resolvconf(8), and to reap the child process.
- A service is used to determine whether a given interface's
link-local address is useable (i.e., not duplicated or undergoing
DAD). This information is supplied by getifaddrs(3), which reads
a sysctl not available in capability mode. The SIOCGIFCONF socket
ioctl provides equivalent information and can be used in capability
mode, but I decided against it for now because of some limitations
of that interface.
In addition to these new services, cap_syslog(3) is used to send
messages to syslogd.

newvers.sh takes upwards of 4-5 seconds to complete on trees checked
out from github, due to searching the entire history for non-existent
git-svn metadata. Similarly, if one does not check out notes, we
again search the entire history for notes. That makes newvers.sh very
slow for many github users.
To fix this in a fair way, limit the history search to the last 10K
commits: if you're more than 10K commits out of sync, then you've
forked the project, and our SVN rev is no longer very important to you.
Due to how git implements --grep in conjunction with -n, --grep has been
removed for performance reasons (git does not seem to limit its search
to the -n limit in this case, and takes just as long as it did with no
limit).
