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.

These will be expanded later as I come up with good test cases; for now,
these seem to be enough to trigger bugs in base gnugrep and expose missing
features in bsdgrep.
The libxo xml feature of adding an annotation with the "original"
address from the utmpx file if it is different than the final "from"
field was broken by r351379. This was pointed out by the gcc error
that save_p might be used uninitialized. Save the original address
as needed in each entry, don't just use the last one from the previous
loop.

Ouput format of last(1) is broken for non UTF-8 locales
since it got libxo(3) support. It uses strftime(3) that produces
non UTF-8 strings passed to xo_emit(3) with wrong %s format -
it should be %hs in this case, so xo_emit(3) produces empty output.
This change is basically no-op when locale is of UTF-8 type,
f.e. en_GB.UTF-8 or ru_RU.UTF-8 or sr_RS.UTF-8@latin.
It fixes output for other locales.

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.

- UMA_XDOMAIN enables an additional per-cpu bucket for freed memory that
was freed on a different domain from where it was allocated. This is
only used for UMA_ZONE_NUMA (first-touch) zones.
- UMA_FIRSTTOUCH sets the default UMA policy to be first-touch for all

nfsstat -s prints bogus large numbers for the Server Re-Failed and Server

Although I know nothing about libxo, these lines aren't titles and this
patch seems to fix the problem, so I am committing it for rea@ who emailed
it to me.
It also deleted the trailing ':' from the title lines, since those were not

If there is a more correct fix, someone conversant with libxo will need
to do so.

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.

it can be re-added behind a WITHOUT_IPSEC build option.
