This flag is used in field 'cr_flags', which is never directly visible
outside the kernel. That field is however exported through 'struct
kinfo_proc' objects (field 'ki_cr_flags'), either from the kernel via
sysctls or from libkvm, and is supposed to contain exported flags
prefixed with KI_CRF_ (currently, KI_CRF_CAPABILITY_MODE and
KI_CRF_GRP_OVERFLOW, this second one being a purely userland one
signaling overflow of 'ki_groups').
Make sure that KI_CRF_CAPABILITY_MODE is the flag actually exported and
tested by userland programs, and hide the internal CRED_FLAG_CAPMODE.
As both flags are currently defined to the same value, this doesn't
change the KBI, but of course does change the KPI. A code search via
GitHub and Google fortunately doesn't reveal any outside uses for
CRED_FLAG_CAPMODE.
While here, move assignment of 'ki_uid' to a more logical place in
kvm_proclist(), and definition of XU_NGROUPS as well in 'sys/ucred.h'
(no functional/interface changes intended).

(cherry picked from commit 09290c3a0c)
A ports exp-run (PR 283410) showed one port to be affected
(sysutils/procs), which has been fixed upstream and in the ports tree.
All additional indirect references to CRED_FLAG_CAPMODE we found after
the code search mentioned in the original commit message are
automatically generated from our headers by FFI mechanisms, so
automatically disappear at recompilation (and the KBI is not changed, as
explained above, so recompilation is not needed).
The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

Add PS_MODE_NO_KINFO_PROC cmd modifier that indicates that neither
process list should be queried from the kernel, nor list of pids or `-a`
switch provided on the command line to filter the output.
This is intended for use by commands that query information not
neccessary attributed to specific process.

Crypto file descriptors were added in the original OCF import as a way
to provide per-open data (specifically the list of symmetric
sessions). However, this gives a bit of a confusing API where one has
to open /dev/crypto and then invoke an ioctl to obtain a second file
descriptor. This also does not match the API used with /dev/crypto on
other BSDs or with Linux's /dev/crypto driver.
Character devices have gained support for per-open data via cdevpriv
since OCF was imported, so use cdevpriv to simplify the userland API
by permitting ioctls directly on /dev/crypto descriptors.
To provide backwards compatibility, CRIOGET now opens another
/dev/crypto descriptor via kern_openat() rather than dup'ing the
existing file descriptor. This preserves prior semantics in case
CRIOGET is invoked multiple times on a single file descriptor.

The intent is to provide bsd-specific flags relevant to interpreter
and C runtime. I did not want to reuse AT_FLAGS which is common ELF
auxv entry.
Use bsdflags to report kernel support for sigfastblock(2). This
allows rtld and libthr to safely infer the syscall presence without
SIGSYS. The tunable kern.elf{32,64}.sigfastblock blocks reporting.

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.
