The use of atomic_sub_64() in zfs_zstd.c was breaking the 32-bit build on
platforms without native 64-bit atomics due to atomic_sub_64() not being
available, and no fallback being provided in _STANDALONE.
Provide a standalone stub to match atomic_add_64() using simple math.
While this is not actually atomic, it does not matter in libsa context,
since it always runs single-threaded and does not run under a scheduler.

zstd: track allocator statistics
Note that this only tracks sizes as requested by the caller.
Actual allocated space will almost always be bigger (e.g., rounded up to
the next power of 2 or page size). Additionally the allocated buffer may
be holding other areas hostage. Nonetheless, this is a starting point
for tracking memory usage in zstd.

Add line number information to more warning and error messages.
Detect #else and #endif without corresponing #ifdef/#ifndef as error.
Detect missing #endif at end of file and print warning but continue.
Support for #undef has been added to reverse the effect of a prior #define.
It is no error if the argument value has not been defined before.
These changes may cause error aborts on malformed input files (e.g. with
spurious #else or #endif), but no such errors exist in the calendar files
in the FreeBSD base system and the calendar-data port and all tests pass.
More tests will be added in a follow-up commit to detect regressions that
might affect the newly added features.
This commit ends a series of updates that enhance the pre-processor and
make it behave much more like prior versions of the calendar progarm that
called cpp to pre-process the data files.

Bring in the long-overdue 4.4BSD-Lite2 rev 8.3 by cgd of
sys/ioccom.h. This uses UL suffix for the IOC_* constants so they
don't sign extend. Also bring in the handy diagram from NetBSD's

in a way that's semantically the same but more compact.

Prior versions of FreeBSD (11.x) may have produced a corrupt extattr file.
(Specifically, r312416 accidentally fixed this defect by removing a strcpy.)
CURRENT FreeBSD supports disk images from those prior versions of FreeBSD.
Validate the internal structure as soon as we read it in from disk, to
prevent these extattr files from causing invariants violations and DoS.
Attempting to access the extattr portion of these files results in
EINTEGRITY. At this time, the only way to repair files damaged in this way
is to copy the contents to another file and move it over the original.

These images were switched to MBR in r281876 as a way to cope with a
hard-coded partition GUID in QEMU's default EFI firmware. Enough time
has passed that this is no longer a problem; QEMU versions >= 4.0
include a copy of edk2 EFI firmware that can detect the root filesystem
properly. Alternatively, sysutils/u-boot-qemu-arm64 can be used.
Switch back to building these images with a GPT partition table, and

The return code of write_partition_layout() doesn't bubble up, so an
invocation of make vm-release for an incorrect/unsupported target will
appear to succeed while make vm-install will fail due to missing

properly.
Upgrade this case to print a message to stderr, and exit in place. This

Each TLS send tag in mlx5 contains a nested rate limit send tag.
Previously, the driver was calling internal functions to manage the
nested tag. Calling free methods directly instead of m_snd_tag_rele()
leaked send tag references and references on the ifp. Changes to use
the ifp methods for the nested tag for other methods are more cosmetic
but do simplify the code.
