* Unicode. User interface handles multi-column characters. API can
handle char* like a multibyte character string. Internally wide
characters are used for keyboard input, to adapt word wrapping and
dynamic text auto-sizing for multi-column characters.
* Forms refactoring. Complete rewrite deleting libformw dependency.
* Theme. New utility options to save and load custom theme at run-time.
* TUI navigation. Added keys to navigate input components. Changed
default focus behavior of input dialogs to be LGPL-dialog-like; a new
option can set the previous whiptail-like behavior.

The divert(4) is not a protocol of IPv4. It is a socket to
intercept packets from ipfw(4) to userland and re-inject them
back. It can divert and re-inject IPv4 and IPv6 packets today,
but potentially it is not limited to these two protocols. The
IPPROTO_DIVERT does not belong to known IP protocols, it
doesn't even fit into u_char. I guess, the implementation of
divert(4) was done the way it is done basically because it was
easier to do it this way, back when protocols for sockets were
intertwined with IP protocols and domains were statically
compiled in.
Moving divert(4) out of inetsw accomplished two important things:
1) IPDIVERT is getting much closer to be not dependent on INET.
This will be finalized in following changes.
2) Now divert socket no longer aliases with raw IPv4 socket.
Domain/proto selection code won't need a hack for SOCK_RAW and
multiple entries in inetsw implementing different flavors of
raw socket can merge into one without requirement of raw IPv4
being the last member of dom_protosw.

into ffs_sbsearch() to allow use by other parts of the system.
Historically only fsck_ffs(8), the UFS filesystem checker, had code
to track down and use alternate UFS superblocks. Since fsdb(8) used
much of the fsck_ffs(8) implementation it had some ability to track
down alternate superblocks.
This change extracts the code to track down alternate superblocks
from fsck_ffs(8) and puts it into a new function ffs_sbsearch() in
sys/ufs/ffs/ffs_subr.c. Like ffs_sbget() and ffs_sbput() also found
in ffs_subr.c, these functions can be used directly by the kernel
subsystems. Additionally they are exported to the UFS library,
libufs(8) so that they can be used by user-level programs. The new
functions added to libufs(8) are sbfind(3) that is an alternative
to sbread(3) and sbsearch(3) that is an alternative to sbget(3).
See their manual pages for further details.
The utilities that have been changed to search for superblocks are
dumpfs(8), fsdb(8), ffsinfo(8), and fsck_ffs(8). Also, the prtblknos(8)
tool found in tools/diag/prtblknos searches for superblocks.
The UFS specific mount code uses the superblock search interface
when mounting the root filesystem and when the administrator doing
a mount(8) command specifies the force flag (-f). The standalone UFS
boot code (found in stand/libsa/ufs.c) uses the superblock search
code in the hope of being able to get the system up and running so
that fsck_ffs(8) can be used to get the filesystem cleaned up.
The following utilities have not been changed to search for
superblocks: clri(8), tunefs(8), snapinfo(8), fstyp(8), quot(8),
dump(8), fsirand(8), growfs(8), quotacheck(8), gjournal(8), and
glabel(8). When these utilities fail, they do report the cause of
the failure. The one exception is the tasting code used to try and
figure what a given disk contains. The tasting code will remain
silent so as not to put out a slew of messages as it trying to taste
every new mass storage device that shows up.

A future commit will actually implement //IGNORE so that applications
using base iconv can, e.g., sanitize UTF-8 strings. To do this, the
iconv_std module needs to be able to determine the minimum width for any
given encoding so that it can skip that many bytes in the input buffer.
This is mainly an issue for UTF-16 and UTF-32.
This commit bumps shlib versions to 5 for libiconv modules to reflect
the ABI change. It also fixes OptionalObsoleteFiles to remove the
libiconv modules if WITHOUT_ICONV is in use.
re: _ENCODING_MB_CUR_MIN, note that this file (citrus_stdenc_template.h)
is included at the bottom of an encoding *implementation*, so the
implementation is free to #define it prior. UTF1632 is a good example,
as it redefines the minimum to be a property on the encodinginfo, and
the minimum is set to 2 or 4 bytes for UTF-16 and UTF-32 respectively.

Summary:
This allows installing packages that depend on kerberos libraries
without pulling in all the binaries. It also moves libgssapi to runtime
to allow installing kerbereos libraries without adding a dependancy on
the large utilities package. It makes sense to put libgssapi in runtime
rather than kerberos-lib since this is a plugin layer which is intended
to support any GSS-API mechanisms, not just kerberos.
A good example of a package which uses kerberos libraries without
needing the kerberos utilities is sshd. This uses the kerberos GSS-API
libraries to implement its GSSAPIAuthentication option.

Rather than trying to shoehorn flags into the requested superblock
address, create a separate flags parameter to the ffs_sbget()
function in sys/ufs/ffs/ffs_subr.c. The ffs_sbget() function is
used both in the kernel and in user-level utilities through export
to the sbget() function in the libufs(3) library (see sbget(3)
for details). The kernel uses ffs_sbget() when mounting UFS
filesystems, in the glabel(8) and gjournal(8) GEOM utilities,
and in the standalone library used when booting the system
from a UFS root filesystem.
The ffs_sbget() function reads the superblock located at the byte
offset specified by its sblockloc parameter. The value UFS_STDSB
may be specified for sblockloc to request that the standard
location for the superblock be read.
The two existing options are now flags:
UFS_NOHASHFAIL will note if the check hash is wrong but will still
return the superblock. This is used by the bootstrap code to
give the system a chance to come up so that fsck can be run to
correct the problem.
UFS_NOMSG indicates that superblock inconsistency error messages
should not be printed. It is used by programs like fsck that
want to print their own error message and programs like glabel(8)
that just want to know if a UFS filesystem exists on a partition.
One additional flag is added:
UFS_NOCSUM causes only the superblock itself to be returned, but does
not read in any auxiliary data structures like the cylinder group
summary information. It is used by clients like glabel(8) that
just want to check for possible filesystem types. Using UFS_NOCSUM
skips the superblock checks for csum data which allows superblocks
that have corrupted csum data to be read and used.
The validate_sblock() function checks that the superblock has not
been corrupted in a way that can crash or hang the system. Unless
the UFS_NOMSG flag is specified, it will print out any errors that
it finds. Prior to this commit, validate_sblock() returned as soon
as it found an inconsistency so would print at most one message.
It now does all its checks so when UFS_NOMSG has not been specified
will print out everything that it finds inconsistent.

Implement Linux-variant of MSG_TRUNC input flag used in recv(), recvfrom() and recvmsg().
Posix defines MSG_TRUNC as an output flag, indicating packet/datagram truncation.
Linux extended it a while (~15+ years) ago to act as input flag,
resulting in returning the full packet size regarless of the input
buffer size.
It's a (relatively) popular pattern to do recvmsg( MSG_PEEK | MSG_TRUNC) to get the
packet size, allocate the buffer and issue another call to fetch the packet.
In particular, it's popular in userland netlink code, which is the primary driving factor of this change.
This commit implements the MSG_TRUNC support for SOCK_DGRAM sockets (udp, unix and all soreceive_generic() users).

Historically, GEOM utilities (gpart(8), gstripe(8), gmirror(8),
etc) used the gctl_error() routine to report errors. If they called
gctl_error() they would exit with EXIT_FAILURE, otherwise they would
return with EXIT_SUCCESS. If they used gctl_error() to output an
informational message, for example when run with the -v (verbose)
option, they would mistakenly exit with EXIT_FAILURE. A further
limitation of the gctl_error() function was that it could only be
called once. Messages from any additional calls to gctl_error()
would be silently discarded.
To resolve these problems a new function, gctl_msg() has been added.
It can be called multiple times to output multiple messages. It
also has an additional errno argument which should be zero if it is
an informational message or an errno value (EINVAL, EBUSY, etc) if
it is an error. When done the gctl_post_messages() function should
be called to indicate that all messages have been posted. If any
of the messages had a non-zero errno, the utility will EXIT_FAILURE.
If only informational messages (with zero errno) were posted, the
utility will EXIT_SUCCESS.

2. Add sanitizer list to lib/libclang_rt/Makefile, taken from the list of
libraries that llvm-devel port builds.
3. powerpc64le supports the same sanitizers that powerpc64, but powerpc64le
also supports xray* sanitizers.
4. lib/libclang_rt/xray/Makefile hardcodes amd64-specific files, so that needs
to be conditionalized.
5. Sanitizers are not enabled for powerpc, because powerpc supports only
builtins and profile.

Merge commit 44cdca37c01a from llvm git (by Arthur O'Dwyer):
[libc++] Define `namespace views` in its own detail header.
Discovered in the comments on D118748: we would like this namespace
to exist anytime Ranges exists, regardless of whether concepts syntax
is supported. Also, we'd like to fully granularize the <ranges> header,
which means not putting any loose declarations at the top level.

This updates llvm, clang, compiler-rt, libc++, libunwind, lld, lldb and
openmp to llvmorg-14-init-18294-gdb01b123d012, the last commit before
the upstream release/14.x branch was created.

Summary:
These functions are missing from the library itself, and exist solely in
the header. This breaks a few ports that expect libm to have the
symbols in the library itself.
Questions on MFC-ability: Can this be MFC'd to 13.2, and how?

On success gnu libc sched_getaffinity() should return 0, unlike underlying
Linux syscall which returns the size of CPU mask copied to user.
PR: 263939
MFC after: 2 weeks
Linux has more tolerant checks of the user supplied cpuset_t's.
Minimum cpuset_t size that the Linux kernel permits in case of
getaffinity() is the maximum CPU id, present in the system / NBBY,
the maximum size is not limited.
For setaffinity(), Linux does not limit the size of the user-provided
cpuset_t, internally using only the meaningful part of the set, where
the upper bound is the maximum CPU id, present in the system, no larger
than the size of the kernel cpuset_t.
Unlike FreeBSD, Linux ignores high bits if set in the setaffinity(),
so clear it in the sched_setaffinity() and Linuxulator itself.

Previously we invoked the sysctl with a NULL buffer to query the size,
allocated a buffer, then invoked it again to fetch the data.
As we only handle the case where the sysctl provides data of the
expected size we can just allocate a correctly-sized buffer to begin
with.

In libthr we use PAGE_SIZE when allocating memory with mmap and to check
various structs will fit into a single page so we can use this allocator
for them.
Ask the kernel for the page size on init for use by the page allcator
and add a new machine dependent macro to hold the smallest page size
the architecture supports to check the structure is small enough.
This allows us to use the same libthr on arm64 with either 4k or 16k
pages.

Apparently some ports on arm require these symbols, and while they were
available in llvm's libunwind, they were never exported via the arm
specific Symbol.map. Put them in the same version block as gcc does
(GCC_3.5).

Similar to ipfw rule timestamps, these timestamps internally are
uint32_t snaps of the system time in seconds. The timestamp is CPU local
and updated each time a rule or a state associated with a rule or state
is matched.
