In 38d1ac34ff SIGATOMIC_{MIN,MAX} were
defined in terms of LONG_{MIN,MAX}. Later, they were switched to
__LONG_{MIN,MAX} in 78fe75bc28 where an
include of machine/_limits.h was added. Switch to using fixed width
INT64_{MIN,MAX} and remove the header pollution.
No functional change.

sig_atomic_t is defined as a long and thus is 64-bit on arm64. For some
reason its limit was incorrectly specified as a 32-bit number. This had
the unfortunate side effect of causing gnulib to override most of the
definitions in stdint.h. On CheriBSD this breaks all software that uses
gnulib in annoying and hard to debug ways.
Technically updating the limits might be an ABI change, but these
defines are largely unused (the only use in tree is in the libc++ test
suite where it's use an assertion that will fail due to this bug).
Further, since the underlying type remains the same, we're just
increasing the range of values a paranoid program might use.

As Coverity reports:
Overwriting tmp in tmp = make_absolute_pwd_glob(tmp, remote_path)
leaks the storage that tmp points to.
Consume the first arg in make_absolute_pwd_glob, and add xstrdup() to
the one case which did not assign to the same variable that was passed
in. With this change make_absolute() and make_absolute_pwd_glob() have
the same semantics with respect to freeing the input string.
This change was reported to OpenSSH in
https://lists.mindrot.org/pipermail/openssh-unix-dev/2022-November/040497.html
but was not acted on. It appears that OpenBSD subsequently received a
Coverity report for the same issue (their Coverity ID 405196) but fixed
only the specific instance reported by Coverity.
This change reverts OpenBSD's sftp.c 1.228 / OpenSSH-portable

As of commit 0bda8d3e9f ("vmm: permit some IPIs to be handled by
userspace") and commit 9cc9abf409 ("bhyve: create all vcpus on
startup"), we have a misbehaviour where AP vCPU threads spin until they
receive a SIPI. In particular, since they are "suspended", they simply
call the VMEXIT_DEBUG handler in a loop, but the handler is a no-op by
default.
This is tricky to fix since the gdb stub isn't aware of whether a given
vCPU is supposed to be running. For 13.2's sake, introduce a simple
workaround wherein the VMEXIT_DEBUG handler sleeps for a short period.
This ensures that host CPU usage remains sane when VMs are starting
without penalizing users of VMEXIT_DEBUG too much.

In fdesc_lookup(), vn_vget_ino_gen() may fail without invoking the
callback, in which case the ref on fp is leaked. This happens if the
fdescfs mount is being concurrently unmounted. Moreover, we cannot
safely drop the ref while the dvp is locked.
So:
- Use a flag variable to indicate whether the ref is dropped.
- Reorganize things to handle the leak.

BYTE_ORDER, LITTLE_ENDIAN and BIG_ENDIAN will be required by the
forthcoming POSIX Issue 8. In addition, they are provided in the BSD
compilation environments. However, depending on the order includes
happend, sys/cdefs.h may or may not be included when endian.h is
included. Include it here so we can safely test __BSD_VISIBLE. Add
visibility when we're compiling in the future for issue 8, but since the
date number for issue 8 hasn't been fixed, use strictly greater than the
issue 7 date.of 200809.
This had the side effect of sometimes (in the traditional BSD
compliation environment)
#if BYTE_ORDER == LITTLE_ENDIAN
and
#if BYTE_ORDER == BIG_ENDIAN
both being true because none of these were defined. This fixes
that. It also fixes including it after <stdio.h> but not before.

The previous code unsuccesfully attempted to report a precise error for
each option in the user list. Moreover, commit 253b2ec199 broke some
ctrl-api-test (see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260547).
With this patch we bail out as soon as an unrecoverable error is detected and
we properly check for copy boundaries. EOPNOTSUPP no longer immediately
returns an error, so that any other option in the list may be examined
by the caller code and a precise report of the (un)supported options can
be returned to the user.
With this patch, all ctrl-api-test unit tests pass again.

The TCP_TXTLS_ENABLE and TCP_RXTLS_ENABLE socket option handlers check
whether the socket is listening socket and fail if so, but this check is
racy. Since we have to lock the socket buffer later anyway, defer the
check to that point.
ktls_enable_tx() locks the send buffer's I/O lock, which will fail if
the socket is a listening socket, so no explicit checks are needed. In
ktls_enable_rx(), which does not acquire the I/O lock (see the review
for some discussion on this), use an explicit SOLISTENING() check after
locking the recv socket buffer.
Otherwise, a concurrent solisten_proto() call can trigger crashes and
memory leaks by wiping out socket buffers as ktls_enable_*() is
modifying them.
Also make sure that a KTLS-enabled socket can't be converted to a
listening socket, and use SOCK_(SEND|RECV)BUF_LOCK macros instead of the
old ones while here.
Add some simple regression tests involving listen(2).

"adrl" is a pseudo-instruction used to calculate an address relative
to PC. It's not recognized by clang resulting in a compilation error.
I've stumbled upon it when trying to integrate the bsaes-armv7 assmebly
logic into FreeBSD kernel, which uses clang as it's default compiler.
Note that this affect the build only if BSAES_ASM_EXTENDED_KEY is
defined, which is not the default option in OpenSSL.
The solution here is to replace it with an add instruction.
This mimics what has already been done in !BSAES_ASM_EXTENDED_KEY logic.
Because of that I've marked this as trivial CLA.
