During testing of the pNFS client, it was observed that an RPC could get
stuck in sosend() for a very long time if the network connection to a DS
had failed. This is fixed by setting SO_SNDTIMEO on the TCP socket.
This is only done when CLSET_TIMEOUT is done and this is not done by any
use of the krpc currently in the source tree, so there should be no effect
on extant uses.
A future patch will use CLSET_TIMEOUT for TCP connections to DSs.

We no longer really need a separate zfsloader. It was useful when we
were first supporting ZFS and had limited ability to properly boot off
of ZFS without the special boot loader. Now that the boot loader has
matured, go the way loader.efi pioneered and just build one
binary. Change the name of the loader to load in the secondary boot
blocks to be just /boot/loader. Provide a symbolic link from zfsloader
to loader so people who have not upgraded their boot blocks are not
affected. This has the happy benefit of making coexistence easier as
well (fewer binaries in the matrix).

This corrects a mistake introduced to the cryptocheck tool in r331418.
Our CRYPTO_BLAKE2B and CRYPTO_BLAKE2S algorithms refer to either the plain,
unkeyed hashes (specified with cri_klen = 0), or a Blake2-specific keyed MAC
(when a cri_key is provided).
In contrast, OpenSSL's Blake2 algorithms only provide the plain hash.
Cryptocheck's T_HMAC corresponds to OpenSSL's HMAC() routine, which is the
ordinary HMAC construction applied to any plain, unkeyed hash. We don't
have any HMAC-Blake2 cipher modes in OCF, so fix the test to only test
Blake2 as a plain hash.
(Ideally we would test keyed Blake2 as well, but that is left as future
work.)

Code analysis and runtime analysis using truss(8) indicate that the only
privileged operations performed by ntpd are adjusting system time, and
(re-)binding to privileged UDP port 123. These changes add a new mac(4)
policy module, mac_ntpd(4), which grants just those privileges to any
process running with uid 123.
This also adds a new user and group, ntpd:ntpd, (uid:gid 123:123), and makes
them the owner of the /var/db/ntp directory, so that it can be used as a
location where the non-privileged daemon can write files such as the
driftfile, and any optional logfile or stats files.
Because there are so many ways to configure ntpd, the question of how to
configure it to run without root privs can be a bit complex, so that will be
addressed in a separate commit. These changes are just what's required to
grant the limited subset of privs to ntpd, and the small change to ntpd to
prevent it from exiting with an error if running as non-root.

I had naively assumed that building kernel would be sufficient to test that
the header is sane. However, it turns out this now needs -fms-extensions to
build. Rather than sprinkling -fms-extensions all over the place, revert
for now, and revisit with a better fix.
Summary:
Ports like sysutils/lsof troll through kernel structures, and
therefore include kernel headers and all the dirty secrets involved. struct
vm_page includes the struct md_page inline, which currently is only defined
if AIM or BOOKE is defined. Thus, by default, sysutils/lsof cannot build,
due to the struct md_page having an incomplete type. Fix this by merging
the two struct definitions into an anonymous struct-union.
A similar change could be made to unify the pmap structures as well.

On i386 and amd64, add a vm_phys segment for physical memory used to
store the kernel binary and other preloaded data. This makes it
possible to free such memory back to the system once it is no longer
needed, e.g., when a preloaded kernel module is unloaded. Previously,
it would have remained unused.

multithreaded programs that was addressed by r329254 was in the
implementation of pmap_enter() on some architectures, notably, amd64.
kib@, markj@ and I have audited all of the pmap_enter() implementations,
and fixed the broken ones, specifically, amd64 (r335784, r335971), i386
(r336092), mips (r336248), and riscv (r336294).
To be clear, the reason to address the problem within pmap_enter() and
revert r329254 is not just a matter of principle. An effect of r329254
was that a copy-on-write fault actually entailed two page faults, not
one, even for single-threaded programs. Now, in the expected case for
either single- or multithreaded programs, we are back to a single page
fault to complete a copy-on-write operation. (In extremely rare
circumstances, a multithreaded program could suffer two page faults.)

Rescale earlier so that a scale factor of 2 can be combined with a non-
scale divisor of 2, so that the division doesn't shift out a bit. In the
usual case where the scale factor is just 1, the division may shift out a
bit, but then the underflow is not spurious and the inaccuracies are harder
to fix.
