Commit 981ef32230 enabled marking of potentially bad
session slots when an RPC is interrupted if the "intr"
mount option is used. As such, it no longer makes
sense to call nfscl_hasexpired() for I/O operations that
reply NFSERR_BADSTATEID for NFSv4.1/4.2, which does a full
recovery of NFSv4 open state, destroying all byte range locks.
Recovery of open state should not be usually needed, since
the session slot has been marked potentially bad and,
although opens for the process that has been terminated via
a signal may be broken, locks for other processes will still
be valid.
This patch disables calls to nfscl_hasexpired for NFSv4.1/4.2
mounts, when I/O RPCs receive NFSERR_BADSTATEID replies.
It does not affect the behaviour of NFSv4.0 mounts nor
hard (non "intr") mounts.

To deal with broken session slots caused by the use of the
"soft" and/or "intr" mount options, nfsv4_sequencelookup()
has been modified to track the potentially broken session
slots (commit 40ada74ee1). Then, when all session slots
are potentially broken, nfsv4_sequencelookup() does a
DeleteSession operation, so that the NFSv4.1/4.2 server will
reply NFSERR_BADSESSION to uses of the session.
The client will then recover by doing a CreateSession to
acquire a new session.
This patch adds the code that marks potentially bad
slots, so that the above semantics become functional.
It has been successfully tested against a FreeBSD
NFSv4.1/4.2 server, but does not work against a Linux 5.15
NFSv4.1/4.2 server. (The Linux 5.15 server creates
a new session with the same sessionid as the destroyed
one and, as such, keeps returning NFSERR_BADSESSION.
I believe this is a bug in the Linux server.)
However, this should not cause a regression and will
make "intr" mounts fairly usable against the NFSv4.1/4.2
servers where it works.

Currently, processing of IPv6 local traffic is partially broken:
link-local connection fails and global unicast connect() takes
3 seconds to complete.
This happens due to the combination of multiple factors.
IPv6 code passes original interface "origifp" when passing
traffic via loopack to retain the scope that is mandatory for the
correct hadling of link-local traffic. First problem is that the logic
of passing source interface is not working correcly for TCP connections,
resulting in passing "origifp" on the first 2 connection attempts and
lo0 on the subsequent ones. Second problem is that source address
validation logic skips its checks iff the source interface is loopback,
which doesn't cover "origifp" case.
More detailed description is available at https://reviews.freebsd.org/D35732
Fix the first problem by untangling&simplifying ifp/origifp logic.
Fix the second problem by switching source address validation check to
using M_LOOP mbuf flag instead of interface type.

This patch adds support for session slots marked bad
to nfsv4_sequencelookup(). An additional boolean
argument indicates if the check for slots marked bad
should be done.
The "cred" argument added to nfscl_reqstart() by
commit 326bcf9394 is now passed into nfsv4_setquence()
so that it can optionally set the boolean argument
for nfsv4_sequencelookup(). When optionally enabled,
nfsv4_setsequence() will do a DestroySession when all
slots are marked bad.
Since the code that marks slots bad is not yet committed,
this patch should not result in a semantics change.

Add the necessary glue to get blake3 building for the boot loaded as
well as connected to the ZFS system so it is useful.
On some platforms, we create references to blake3_sse2_impl and
blake3_sse41_impl ops structs to utilize SIMD. These aren't present on
x86 (since we dind't ask for them), but are on aarch64 with no
implementation. Since we don't want SIMD in the boot loader, have these
all return 'unsupported' always. This should be fixed upstream to allow
more flexibility in this selection, but for now we use this hack to not
modify the sys/contrib/openzfs with difficult to maintain hacks while
an upstreamable solution is found.

sys/blake3.h is not safe to include in a standalone environment. It
assumes, unwisely, that there's only kernel or userland. The userland
choice is bad due to imperfections in how we handle stdlib.h in this
environment (we wind up including the host's stdlib.h, it expects a
standard FreeBSD setup which the gymnastics we've done to create a
OpenSolaris/Illumos-like environment interfere with). Thankfully, in
this case we can just pretend to be the kernel for a little bit by
defining _KERNEL and the undefing it after we exit.

skipped. Next, there's a problem including string.h to get the mem*

properly. I had wanted to define it when I was upstreaming changes to
include/os/freebsd/spl/sys/zfs_context.h, but they ran into resistance
so I'm defining that here now (it is also defined in zstd_shim.c, but
that will disappear once the issues it works around are
cleared). Finally, sys/sysmacros.h has to be included now before
sys/atomic.h, but upstream includes it after so include it here so that
the guards make the out-of-order includes in upstream irrelevant.

Commit a7bb120f8b added a printf for the case where recovery
has not marked the session defunct by setting nfsess_defunct
to 1. It turns out that nfscl_hasexpired() calls
nfsrpc_setclient() directly, without setting nfsess_defunct.
This patch replaces the printf with code that sets
nfsess_defunct to 1 to handle this case.
If SIGTERM is issued to a process when it is doing I/O on
an "intr" mount, the NFSv4 server may reply NFSERR_BADSTATEID,
due to the Open being prematurely closed.
This can result in a call to nfscl_hasexpired() to do a
recovery.
This would explain at least one hang described in the PR.
