As with sha256 add support for accelerated sha512 support to libmd on

with the needed intrinsics. Gcc should also support them, however from
a currently unknown release.

The fr_info struct contains a summary of a packet. One of its fields
is a pointer to the ifnet struct the packet arrived on. It is pointed
to by a void* because ipfilter supports multiple O/Ses. Unfortunately
this makes it difficult it examine with DTrace. Defining fin_ifp as a
pointer to an ifnet struct makes the struct it points to using a DTrace
script possible.

To quote the manual:
The pointer passed in as name and type is saved rather than the data
it points to. The data pointed to must remain stable until the mutex
is destroyed.
It seems that the type is actually copied, but the name is stored as
a pointer indeed.
mmc_cam_sim_alloc used a name stored on stack.
So, a corrupt mutex name would be reported.
For example:
lock order reversal: (sleepable after non-sleepable)
1st 0xd7285b20 <8A><C0><C0>P@<C1><D0>P@<C1>^D^A (aw_mmc_sim, sleep mutex) @ /usr/devel/git/orange/sys/cam/cam_xpt.c:2804
This change moves the name to struct mmc_sim.
Also, that name is used as the sim name as well.
Unused mtx_name variable is removed too.
This seems to be required even if the watchdog is accessed via the common
MMIO space.

For pNFS mounts to mirrored Flexible File layout pNFS servers,
the "must_commit" component in the nfsclwritedsdorpc
structure must be checked and the "must_commit" argument passed
into nfscl_doiods() must be updated. Technically, only writes to
the DS with a writeverf change must be redone, but since this
occurrence will be rare, the must_commit argument to nfscl_doiosd()
is set to 1, so all writes to all DSs will be redone.
This bug would affect few, since use of mirrored pNFS servers
is rare and "writeverf" rarely changes. Normally "writeverf"
only changes when a NFS server reboots.

Revert commit e655e74a318e from llvm git (by Peter Collingbourne):
AST: Create __va_list in the std namespace even in C.
This ensures that the mangled type names match between C and C++,
which is significant when using -fsanitize=cfi-icall. Ideally we
wouldn't have created this namespace at all, but it's now part of
the ABI (e.g. in mangled names), so we can't change it.

As reported by Jessica in https://reviews.llvm.org/D104830#3129527, this
upstream change is implemented in such a way that it breaks DTrace's
CTF. Since a proper fix has not yet been forthcoming, and we are
unaffected by the (CFI-related) problem upstream was trying to address,
revert the change for now.

OVMF creates two separate .fd files, a _CODE.fd file containing
the UEFI code, and a _VARS.fd file containing a template of an
empty UEFI variable store.
OVMF decides to write variables to the memory range just below the
boot rom code if it detects a CFI flash device. So here we add
just the barest facsimile of CFI command handling to bootrom.c
that is needed to placate OVMF.

Only accept at most superpage alignment, or if the arch does not have
superpages supported, artificially limit it to PAGE_SIZE * 1024.
This is somewhat arbitrary, and e.g. could change what binaries do
we accept between native i386 vs. amd64 ia32 with superpages disabled,
but I do not believe the difference there is affecting anybody with
real (useful) binaries.

Without this patch, the KASSERT(must_commit == 0,..) can be
triggered by the writeverf in the Direct I/O write reply changing.
This is not a situation that should cause a panic(). Correct
handling is to ignore the change in "writeverf" for Direct
I/O, since it is done with NFSWRITE_FILESYNC.
This patch modifies the semantics of the "must_commit"
argument slightly, allowing an initial value of 2 to indicate
that a change in "writeverf" should be ignored.
It also fixes the KASSERT()s.
This bug would affect few, since Direct I/O is not enabled
by default and "writeverf" rarely changes. Normally "writeverf"
only changes when a NFS server reboots, however I found the
bug when testing against a Linux 5.15.1 kernel nfsd, which
replied to a NFSWRITE_FILESYNC write with a "writeverf" of all
0x0 bytes.

Introduce new MSGBUF_WRAP flag, indicating that buffer has wrapped
at least once and does not keep zeroes from the last msgbuf_clear().
It allows msgbuf_peekbytes() to return only real data, not requiring
every consumer to trim the leading zeroes after doing pointless copy.
The most visible effect is that kern.msgbuf sysctl now always returns
proper zero-terminated string, not only after the first buffer wrap.
