This merge brings in a couple new files, which needed to be attached to the
build; a new dependency on <limits.h>, which must be stubbed; and a name
change in the Context parameter constants, from ZSTD_p_foo to ZSTD_c_foo.
Significantly, it fixes a kernel build error with GCC where floating-point
functions were included in the kernel build, by hiding them under the same
compile-time #ifdef that already covered their invocation. That issue was
introduced to FreeBSD in the 1.3.7 update and tracked upstream here:
https://github.com/facebook/zstd/issues/1386

SVN r340744 erroneously changed pfind() to return any process including
zombies and pfind_any() to return only non-zombie processes.
In particular, this caused kill() on a zombie process to fail with [ESRCH].
There is no direct test case for this but /usr/tests/bin/sh/builtins/kill1.0
occasionally triggers it (as reported by lwhsu).
Conversely, returning zombies from pfind() seems likely to violate
invariants and cause panics, but I have not looked at this.

The long double aliases of double functions are only exposed as aliases if
LDBL_MANT_DIG is 53 (same as DBL_MANT_DIG). Without float.h included these
files were not exposing weak aliases as expected, leading to link failures

This is primarily aimed at failed updates due to package conflicts, and
affects treatment of failed updates. Whereas before potentially a large
number of packages would need to be synced for each attempt, they can now
be persisted. Requires rsync. There may be better ways to implement this,
e.g. using secondary cache path that is only used on followup attempts and
then wiped on success, which avoids polluting current cache.
Mutexes in I/O path there were used twice per I/O to atomically access
several variables to close and/or destroy the device on last request
completion. I found the way to fit all required info into one integer,
suitable for atomic operations. It opened race window on device close,
but addition of timeout to the msleep() there should cover it.
Profiling shows removal of significant spinning time on those mutexes
and IOPS increase from ~600K to >800K to NVMe on 72-core systems.

Previous code typically crashed in case of NVMe device unplug or even clean
detach while some I/Os are still in flight. To fix this the new code calls
disk_gone() and waits for confirmation of all references gone before calling
disk_destroy(), freeing other resources and allowing controller detach.
While there, fix disk lists locking and reimplement unit numbers assignment.

We need to tell vm_fault the reason for the fault was because we tried to
execute from the memory location. Without this it may return with success
as we only request read-only memory, then we return to the same location
and try to execute from the same memory address. This leads to an infinite
loop raising the same fault and returning to the same invalid location.

Addition of the new errno values requires adding new elements to
sys_errlist array, which is actually ABI-incompatible, since ELF
records the object size. Expand array in advance to 150 elements so
that we have our users to go over the issue only once, at least until
more than 53 new errors are added.
I did not bumped the symbol version, same as it was not done for
previous increases of the array size. Runtime linker only copies as
much data into binary object on copy relocation as the binary'object
specifies. This is not fixable for binaries which access sys_errlist
directly.
While there, correct comment and calculation of the temporary buffer
size for the message printed for unknown error. The on-stack buffer
is used only for the number and delimiter since r108603.

It is intended to assist the creation and management of virtual machines
that have their rootfs on ZFS on hosts that also have their rootfs on
ZFS. These situations cause SPA namespace collisions when the standard
name rpool is used in both cases. The solution is either to give each
guest pool a name unique to the host, which is not always desireable, or
boot a VM environment containing an ISO image to install it, which is
cumbersome.

This behavior is transient in nature and subsequent reads will return
