This commit does not attempts to change the current behavior of units(1).

r356242 updated nfsstat.c to report that the "-M" and "-N" options were
being ignored. These options have never had any meaning for the new NFS
code (which is now the only NFS code).
This patch updates the man page to reflect this.
This is a content change.
The "-M" and "-N" options for nfsstat were used by the old NFS code and
have never done anything for the new NFS code.
This patch replaces code that assigns values to variables that are never
used with printf()s noting the options are ignored.
This has the side effect that it gets rid of warnings w.r.t. these
variables being assigned but never used, that occur for some builds.
Noticed during integration of the NFSv4.2 code.
Prior to this patch, nfsstat.c includes files from sys/nfs, sys/nfsclient

and sys/nfsserver) are from the old NFS code and should eventually be
deprecated/removed.

r355992 added listing of NFSv4.2 procedure and operation counts.
This patch updates the nfsstat.1 man page to reflect that change.
This is a content change.
r355677 added NFSv4.2 support to the NFS client and server. It also updated
the nfsstats structure to keep counts for the new procedures (client) and
operations (server) added for NFSv4.2.
This patch updates the "-E" option of nfsstat so that it lists counts for
these new procedures and operations.
This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.
Updating the vendor area to match this layout is next.
- Move libxo.a build to subdirectory (lib/libxo/libxo/Makefile)
- Add .WAIT target to delay encoder build til after libxo
- Use FILES to install encoder library as csv.enc
- Update import script to put xo_config.h in new location
This adds a new -D/--all-repeats option to uniq(1), which outputs each copy
of any repeated lines (as opposed to a single copy of a repeated line). You
can specify a separator option to output a blank line before or after each
group of repeated lines. This adds compatibility with the GNU coreutils
version of uniq(1).
This change also re-groups the -c, -d, -D, -u options in the usage display
and man page to indicate that they are mutally exclusive of each other. This
matches the posix/opengroup definition of uniq(1) command line args. Note
that this change does NOT actually enforce the mutual exclusion in the code,
for now, it simply documents that the arguments should be considered
exclusive with each other.

This is both reasonable and a common GNUism that a lot of ported software
expects.
Universally process \r, \n, and \t into carriage return, newline, and tab
respectively. Newline still doesn't function in contexts where it can't
(e.g. BRE), but we process it anyways rather than passing
UB \n (escaped ordinary) through to the underlying regex engine.
Adding a --posix flag to disable these was considered, but sed.1 already
declares this version of sed a super-set of POSIX specification and this
behavior is the most likely expected when one attempts to use one of these
escape sequences in pattern space.
This differs from pre-r197362 behavior in that we now honor the three
arguably most common escape sequences used with sed(1) and we do so outside
of character classes, too.
Other escape sequences, like \s and \S, will come later when GNU extensions
are added to libregex; sed will likely link against libregex by default,
since the GNU extensions tend to be fairly un-intrusive.

When an empty pattern is encountered in the pattern list, I had previously
broken bsdgrep to count that as a "match all" and ignore any other patterns
in the list. This commit rectifies that mistake, among others:
- The -v flag semantics were not quite right; lines matched should have been
counted differently based on whether the -v flag was set or not. procline
now definitively returns whether it's matched or not, and interpreting
that result has been kicked up a level.
- Empty patterns with the -x flag was broken similarly to empty patterns
with the -w flag. The former is a whole-line match and should be more
strict, only matching blank lines. No -x and no -w will will match the
empty string at the beginning of each line.
- The exit code with -L was broken, w.r.t. modern grep. Modern grap will
exit(0) if any file that didn't match was output, so our interpretation
was simply backwards. The new interpretation makes sense to me.
Tests updated and added to try and catch some of this.

To remain compatible with GNU patch, we should ensure that once we're
removing empty files after a reversed /dev/null patch we don't remove files
that have been modified. GNU patch leaves these intact and just reverses the
hunk that created the file, effectively implying --remove-empty-files for
reversed /dev/null patches.
All of them are needed to be able to boot to single user and be able
to repair a existing FreeBSD installation so put them directly into
FreeBSD-runtime.

Summary:
- basic: test application of patches created by diff -u at the
beginning/middle/end of file, which have differing amounts of context
before and after chunks being added
- limited_ctx: stems from PR 74127 in which a rogue line was getting added
when the patch should have been rejected. Similar behavior was
reproducible with larger contexts near the beginning/end of a file. See
r326084 for details
- file_creation: patch sourced from /dev/null should create the file
- file_nodupe: said patch sourced from /dev/null shouldn't dupe the contents
when re-applied (personal vendetta, WIP, see comment)
- file_removal: this follows from nodupe; the reverse of a patch sourced
from /dev/null is most naturally deleting the file, as is expected based
on GNU patch behavior (WIP)
Some of the procstat tests start a program "while1" and examine the process
using procstat, but did not wait properly for it to start (kill -0 will
succeed immediately after the child process has been created).
Instead, have "while1" write something when it starts, and use a fifo to
wait for that.

The Zstd format bumps the CLOOP major number to 4 to avoid incompatibility
with older systems. Support in geom_uzip(4) is conditional on the ZSTDIO
kernel option, which is enabled in amd64 GENERIC, but not all in-tree
configurations.
mkuzip(8) was modified slightly to always initialize the nblocks + 1'th
offset in the CLOOP file format. Previously, it was only initialized in the
case where the final compressed block happened to be unaligned w.r.t.
DEV_BSIZE. The "Fake" last+1 block change in r298619 means that the final
compressed block's 'blen' was never correct unless the compressed uzip image
happened to be BSIZE-aligned. This happened in about 1 out of every 512
cases. The zlib and lzma decompressors are probably tolerant of extra trash
following the frame they were told to decode, but Zstd complains that the
input size is incorrect.
Correspondingly, geom_uzip(4) was modified slightly to avoid trashing the
nblocks + 1'th offset when it is known to be initialized to a good value.
This corrects the calculated final real cluster compressed length to match
that printed by mkuzip(8).
mkuzip(8) was refactored somewhat to reduce code duplication and increase
ease of adding other compression formats.
* Input block size validation was pulled out of individual compression
init routines into main().
* Init routines now validate a user-provided compression level or select
an algorithm-specific default, if none was provided.
* A new interface for calculating the maximal compressed size of an
incompressible input block was added for each driver. The generic code
uses it to validate against MAXPHYS as well as to allocate compression
result buffers in the generic code.
* Algorithm selection is now driven by a table lookup, to increase ease of
adding other formats in the future.
mkuzip(8) gained the ability to explicitly specify a compression level with
'-C'. The prior defaults -- 9 for zlib and 6 for lzma -- are maintained.
The new zstd default is 9, to match zlib.
Rather than select lzma or zlib with '-L' or its absense, respectively, a
new argument '-A <algorithm>' is provided to select 'zlib', 'lzma', or
'zstd'. '-L' is considered deprecated, but will probably never be removed.
All of the new features were documented in mkuzip.8; the page was also
cleaned up slightly.

This removes all of the architecture-specific functions from truss.
A per-ABI structure is still needed to map syscall numbers to names
and FreeBSD errno values to ABI error values as well as hold syscall
counters. However, the linker set of ABI structures is now replaced
with a simple table mapping ABI names to structures. This approach
permits sharing the same ABI structure among separate names such as
i386 a.out and ELF binaries as well as ELF v1 vs ELF v2 for powerpc64.
A few differences are visible due to using PT_GET_SC_RET to fetch the
error value of a system call. Note that ktrace/kdump have had the
"new" behaviors for a long time already:
- System calls that return with EJUSTRETURN or ERESTART will now be
noticed and logged as such. Previously sigreturn (which uses
EJUSTRETURN) would report whatever random value was in the register
holding errno from the previous system call for example. Now it
reports EJUSTRETURN.
- System calls that return errno as their error value such as
posix_fallocate() and posix_fadvise() now report non-zero return
values as errors instead of success with a non-zero return value.

Historically we have not distinguished between kernel wirings and user
wirings for accounting purposes. User wirings (via mlock(2)) were
subject to a global limit on the number of wired pages, so if large
swaths of physical memory were wired by the kernel, as happens with
the ZFS ARC among other things, the limit could be exceeded, causing
user wirings to fail.
The change adds a new counter, v_user_wire_count, which counts the
number of virtual pages wired by user processes via mlock(2) and
mlockall(2). Only user-wired pages are subject to the system-wide
limit which helps provide some safety against deadlocks. In
particular, while sources of kernel wirings typically support some
backpressure mechanism, there is no way to reclaim user-wired pages
shorting of killing the wiring process. The limit is exported as
vm.max_user_wired, renamed from vm.max_wired, and changed from u_int
to u_long.
The choice to count virtual user-wired pages rather than physical
pages was done for simplicity. There are mechanisms that can cause
user-wired mappings to be destroyed while maintaining a wiring of
the backing physical page; these make it difficult to accurately
track user wirings at the physical page layer.
The change also closes some holes which allowed user wirings to succeed
even when they would cause the system limit to be exceeded. For
instance, mmap() may now fail with ENOMEM in a process that has called
mlockall(MCL_FUTURE) if the new mapping would cause the user wiring
limit to be exceeded.
Note that bhyve -S is subject to the user wiring limit, which defaults
to 1/3 of physical RAM. Users that wish to exceed the limit must tune
vm.max_user_wired.

During processing we maintain symbol offsets in the 64-bit s_so array,
and when writing the archive convert to 32-bit if no offsets are greater
than 4GB. However, this was somewhat inefficient as we looped over the
array twice: first, converting to big endian and second, writing each
32-bit value one at a time (and incorrectly so on big-endian platforms).
Instead, when writing a 32-bit archive shuffle convert symbol data to
big endian (as required by the ar format) and shuffle to the beginning
of the allocation at the same time.
Also correct emission of the symbol count on big endian platforms.
Further changes are planned, but this should fix powerpc64.
