This ensures we use the handle opened with pfctl_open(), and also brings

FreeBSD assumes that sys/types.h includes sys/cdefs.h, so add it here.
FreeBSD also needs __*int*_t defined for software we bootstrap (a lot of
it). GLIBC defines these, but musl does not, so we have to define them
here, even though it looks backwards. There's no good #define to key off
of, so use !defined GLIBC since on Linux defacto there's only two libc
implementations.

string.h defines strmode with a mode_t argument. POSIX states that one
must include sys/types.h to get mode_t, so do that here. This makes musl
happier. We know that sys/types.h will include sys/cdefs.h, so just
replace the latter with the former.

On Linux with musl, sys/cdefs.h isn't included with fcntl.h, so when we
use __BEGIN_DECL and __END_DECL in this file, it fails. There's no harm
in unconditionally including sys/cdefs.h here, so do that to avoid

On Linux, stddef.h will define __size_t to something when size_t is
defined. On FreeBSD, __size_t is an actual typedef which we need for
other parts of the system. If __size_t isn't defined, that tells us we
need to define the fallback __size_t typedef (if it is defined, then we
can't easily redefine it without issues because glob.h will define it to
something different than stddef.h defines it). Add a comment to this

The LK_NOWAIT was added to suppress a witness warning, but LK_NOWITNESS
is more what we mean. This makes pbuf_ctor() more consistent with
buf_alloc(), although, unlike buf_alloc(), for pbuf there should not be
any danger of a wild locker relying on the type stability of the buf to
attempt a lock. That is, this is essentially cosmetic.
Relevant history:

[X86] Add slow div64 tuning flag to Nehalem target (#91129)
This appears to have been missed because later cpus don't inherit from Nehalem tuning much.
Noticed while cleaning up for #90985
Merge commit 8b400de79eff from llvm-project (by Simon Pilgrim):
[X86] Enable TuningSlowDivide64 on Barcelona/Bobcat/Bulldozer/Ryzen Families (#91277)
Despite most AMD cpus having a lower latency for i64 divisions that converge early, we are still better off testing for values representable as i32 and performing a i32 division if possible.
All AMD cpus appear to have been missed when we added the "idivq-to-divl" attribute - this patch now matches Intel cpu behaviour (and the x86-64/v2/3/4 levels).
Unfortunately the difference in code scheduling means I've had to stop using the update_llc_test_checks script and just use old-fashioned CHECK-DAG checks for divl/divq pairs.
Fixes#90985
This fixes possibly worse runtime performance on AMD Zen hardware, when
using -march=znver4 (or any other znver), as opposed to -march=x86-64-v4
or the baseline -march=x86-64. A similar fix is applied for Nehalem.

The existing machine-dependent uma_small_alloc code is almost identical

map addresses involved extra steps in some cases.
The MI/MD split was replaced by a default uma_small_alloc
implementation that can be overridden by architecture-specific code by
defining the UMA_MD_SMALL_ALLOC symbol. Furthermore, UMA_USE_DMAP was
introduced to replace most UMA_MD_SMALL_ALLOC uses.

a port mismatch when using UDP encapsulation.
(2) If net.inet.tcp.blackhole is set to 3, no RST segment is sent in

When biofinish calls g_io_deliver with an error of ENOMEM, that kicks
off the slowdown protocol, forcing I/O to go through g_down rather than
be directly dispatch. One of the side effects is that the I/O is
resubmitted, so the start routines get called recursively, leading to a
recursive lock panic. Rather than make the periph lock recursive, drop
and reacquire the lock around such calls to biofinish.
For nda, this happens only when we can't allocate space to construct a
TRIM. For ada and da, this is only for certain ZONE operations.

Update to eliminate bogus min to ensure 0 was never passed to

limiter still is less than ideal, and this commit doesn't change
