SAM-5 specification states maximum size of command identifier (tag),
defined by specific transports, should not be larger than 64 bits.
While most of supported transports use 32 bits or less, it was
reported that virtio-scsi uses 64 bits. Truncation to 32 bits in
bhyve code caused false tag conflict errors reported and possibly
other issues.
This changes CTL ABI and HA protocol, so CTL_HA_VERSION is bumped.
While we make HA protocol incompatible, increase default maximum
number of ports in CTL from 256 to 1024, matching number of LUNs.
There are many reports from people who need many iSCSI targets with
only one LUN each. Increased memory consumption should be less of
a problem these days.

GCC 12 raises warnings about literal operator suffixes not preceded by
'_' in libc++ headers such as <string_view> as it doesn't recognize
libc++ headers being an implementation of the standard.
GCC 12 also warns about clang-specific pragmas in <locale>.
Disabling these warnings globally for all C++ code is not ideal, but
is a better option than patching libc++ headers to ignore these
warnings.

Clang 15 enforces function definitions using the C89 form rather than
the K&R form. While not strictly a prototype (which is only for a
declaration), use the name that mirror's clang's warning name. Much code
in contrib still uses K&R function definitions, so invent this for
compiling there.

Netlink has a confirmation/error reporting mechanism for the sent
messages. Kernel explicitly acks each messages if requested (NLM_F_ACK)
or if message processing results in an error.
Similarly, for multipart messages - typically dumps, where each message
represents a single object like an interface or a route - another
message, NLMSG_DONE is used to indicate the end of dump and the
resulting status.
As a result, successfull dump ends with both NLMSG_DONE and NLMSG_ERROR
messages.
RFC 3549 does not say anything specific about such case.
Linux adopted an optimisation which suppresses NLMSG_ERROR message
when NLMSG_DONE is already sent. Certain libraries/applications like
libnl depends on such behavior.
Suppress sending NLMSG_ERROR if NLMSG_DONE is already sent, by
setting newly-added 'suppress_ack' flag in the writer and checking
this flag when generating ack.
This change restores libnl compatibility.

scrub rules have defaulted to handling fragments for a long time, but
since we removed "fragment crop" and "fragment drop-ovl" in 64b3b4d611
this has become less obvious and more expensive ("reassemble" being the
more expensive option, even if it's the one the vast majority of users
should be using).
Extend the 'scrub' syntax to allow fragment reassembly to be disabled,
while retaining the other scrub behaviour (e.g. TTL changes, random-id,
..) using 'scrub fragment no reassemble'.

Along with _PSV, _HOT, and _CRT, ACPI supports the _CR3 threshold
which specifies a temperature above which a system should transition
to the S3 standby state.
On FreeBSD, this is more useful than _HOT, which specifies the S4
transition threshold temperature (since FreeBSD does not generally
support the S4 state), or, in many cases, _CRT, since after
transitioning to S3 the system can cool and then be resumed.

A small reduction in build infrastructure complexity; when we had both
Clang and GCC in the tree it was useful to have both built, and choose
one or the other to install as /usr/bin/cc. Now only Clang is in the
tree, and there is no point in building and installing base Clang but
not providing it as cc (and c++, cpp).

Switch /etc/mail/Makefile to use /etc/rc.d/sendmail instead of
/etc/rc.sendmail this switch should have been done 20 years ago.
While here update the documentation to not refer anymore to
mta_start_script
Reported by: Jose Luis Duran <jlduran@gmail.com>
othermta (along with mta_start_script configuration entry in rc.conf)
was a mechanism used to be able to run another mta than sendmail(8) before
"rcng" time 20 years ago.
othermta has not been used since.
${name}_prepend is suboptimal as it is prepended to the actual
command being run. Therefore the term "commandS to prepend"
is misleading and no clear separation takes place for setup tasks
that may be required like changing a config file permission or
generating a configuration file prior to service start.
The other reason is that {argument}_precmd is a service-side
variable and cannot be repurposed from the user-side.
