freebsd32: Fix freebsd11_nstat copyout condition
freebsd11_freebsd32_nstat() invoked copyout(2) when
freebsd11_cvtnstat32() failed and skipped copyout on success. This is
backwards.
Fix this to match freebsd11_freebsd32_nlstat() and freebsd11_nstat(),
and only copy the nstat32 result to userspace when conversion succeeds.

hwpmc: prevent IBS fetch from getting stuck
Both fetch and op IBS sampling have the same problem where we need to
rewrite the control MSR to ensure sampling continues at the correct
rate. I also like this because it resets the counter reducing the
chances that we collect a sample inside the NMI handler.

hwpmc: Fix bug when stopping ibs-op
In ibs_stop_pmc I accidently cleared the fetch max count value rather
than the op max count value, when stopping the op counter. This
mitigates a bug in early pre-zen processors, but breaks using both
counters simultaneously. I also found that the max op count mask needs
to be extended for recent zen processors.

tools/build/Makefile: Always add md4.h to SYSINCS
Since libmd was added to the bootstrap, building main on stable/14
fails because of an incompatibility in its old md4.h. Fix this by
always including md4.h in the bootstrap headers, instead of only
doing so when building on a non-FreeBSD host.

<sys/extattr.h>: use designated initializers for EXTATTR_NAMESPACE_NAMES
This is not a functional change, but it makes it more clear upon
inspection of the definition that the mapping property described is
preserved. Maybe more importantly, if one ends up getting an index
wrong or punching a hole in the name array unexpectedly, then it'll
hopefully manifest more clearly as a (null) or nullptr deref rather than
potentially just emitting the wrong namespace name.
It's noted that this almost certainly invalidates its use in C++, but
there aren't really any known C++ consumers of it- let's just cross
that bridge if we get there.

find: add -xattr and -xttrname
We use -xattr in our openrsync tests for convenience, and it seems like
a good addition to FreeBSD. -xattr and -xattrname will both consult all
available namespaces by default, but -xattrname allows filtering by
namespace using a "user:" or "system:" prefix.

libc: fix memfd_create's HUGETLB handling
The 'simplification' commit referenced below actually broke one aspect
of MFD_HUGETLB: the caller isn't supposed to be required to specify a
size. MFD_HUGETLB by itself without a shift mask just requests a large
page, so we revert that part of memfd_create() back.
While we're here, fix up the related parts of the manpages a little bit,
since MFD_HUGETLB is actually supported. The manpage claims that we
would return ENOSYS if forced mappings weren't supported, but this was
actually not true. However, that seems like a very important
distinction to make between ENOSYS and EOPNOTSUPP, so fix the
implementation to match the docs.

kqueue: don't leak file refs on failure to knote_attach()
We'll subsequently just knote_free() since the knote is barely
constructed, but that bypasses any logic that might release references
on owned files/fops. Defer clearing those until the knote actually owns
them and update the comment to draw the line more clearly.

kqueue: slightly clarify the flow in knlist_cleardel()
This is purely a cosmetic change to make it a little easier on the eyes,
rather than jumping back to the else branch up top. Re-flow it to use
another loop on the outside and just inline the re-lock before we repeat
after awaking from fluxwait.
The !killkn path should maybe issue a wakeup if there's a thread in
KQ_SLEEP so that userland can observe the EOF, but this isn't a
practical problem today: pretty much every case of knlist_clear is tied
to a file descriptor and called in the close(2) path. As a consequence,
potentially affected knotes are almost always destroyed before we even
get to knlist_clear().

tests: kqueue: add a basic test for CPONFORK
Just copy over a timer and a write-filter, be sure that we can observe
both in the child. Maybe the timer should check for a minimum time
passed, but I don't know that we'd be likely to get that wrong.
This also adds a negative test with a kqueue that is *not* set for
CPONFORK being added to the first one, made readable, and confirming
that we don't see a knote for it in the child.
Some other improvements to the test noted in the review are planned in
the short term, but they're not particularly worth blocking adding this
as a basic sanity check.
