As discussed on -current, -stable, -toolchain, and with jhb@ and imp@,
disable the obsolete in-tree GDB 6.1.1 by default. This was kept only
to provide kgdb for the crashinfo tool, but is long-obsolete, does not
support all architectures that FreeBSD does, and held back other work
(such as forcing the use of DWARF2 for kernel debug).
Crashinfo will use kgdb from the gdb package or devel/gdb port, and will
privde a message referencing those if no kgdb is found.

This has been years in the making, and we all knew it was bound to happen
some day. Switch to the BSDL grep implementation now that it's been a
little more thoroughly tested and theoretically supports all of the
extensions that gnugrep in base had with our libregex(3).
Folks shouldn't really notice much from this update; bsdgrep is slower than
gnugrep, but this is currently the price to pay for fewer bugs. Those
dissatisfied with the speed of grep and in need of a faster implementation
should check out what textproc/ripgrep and textproc/the_silver_searcher
can do for them.
I have some WIP to make bsdgrep faster, but do not consider it a blocker
when compared to the pros of switching now (aforementioned bugs, licensing).

While some of the syscalls' behavior were documented and implied in the
RETURN VALUES section by earlier, e.g., the DESCRIPTION sections, as having
behavior of the other calls (`*_fd` vs `*_file` vs `*_link`), there was a lot
of implied return value behavior in the section prior to this change.
Explicitly document the syscall behavior per the current implementation in
sys/kern/vfs_extattr.c so others can better develop based on its explicit
documented behavior instead of having to digest the context of the manpage to
understand the appropriate behavior.

For platforms that don't have any of the memstick, cdrom, or dvdrom
release images (i.e. riscv64), the release-install target will trip up
when invoking md5(1) on the non-existent image files. Skipping this
allows the install to complete successfully.
Add two release flavors for RISC-V. First, the traditional "big-iron"
images, capable of generating distribution sets and VM images. Installer
images won't be built yet, but can be trivially enabled in the future
with the addition of riscv/make-memstick.sh.
Second, a GENERICSD embedded image. I've opted for this instead of
board-specific SD card images as it allows users to just dd the u-boot
they want. The RISC-V hardware ecosystem is still young, so a
configuration for e.g. the new PolarFire SoC Icicle Kit would likely see
very few users.

We assume the boot CPU is always CPU 0 on arm64. To allow for this reserve
cpuid 0 for the boot CPU in the ACPI and FDT cases but otherwise start the
CPU as normal. We then check for the boot CPU in start_cpu and return as if
it was started.
While here extract the FDT CPU init code into a new function to simplify
cpu_mp_start and return FALSE from start_cpu when the CPU fails to start.

The old implementation chose the largest bucket zone such that if the
per-CPU caches are fully populated, the total number of items cached is
no larger than the specified limit. If no such zone existed, UMA would
not do any caching.
We can now use uz_bucket_size_max to set a precise limit on the number
of items in a zone's bucket, so the total size of per-CPU caches can be
bounded more easily. Implement a new policy in uma_zone_set_maxcache():
choose a bucket size such that up to half of the limit can be cached in
per-CPU caches, with the rest going to the full bucket cache. This
fixes a problem with the kstack_cache zone: the limit of 4 * mp_ncpus
items meant that the zone would not do any caching, defeating the whole
purpose of the zone. That's because the smallest bucket size holds up
to 2 items and we may cache up to 3 full buckets per CPU, and
2 * 3 * mp_ncpus > 4 * mp_ncpus.

uz_bucket_size_max is the maximum permitted bucket size. When filling a
new bucket to satisfy uma_zalloc(), the bucket is populated with at most
uz_bucket_size_max items. The maximum number of entries in the bucket
may be larger. When freeing items, however, we will fill per-CPPU
buckets up to their maximum number of entries, potentially exceeding
uz_bucket_size_max. This makes it difficult to precisely limit the
number of items that may be cached in a zone. For example, if one wants
to limit buckets to 1 entry for a particular zone, that's not possible
since the smallest bucket holds up to 2 entries.
Try to solve the problem by using uz_bucket_size_max to limit the number
of entries in a bucket. Note that the ub_entries field is initialized
upon every bucket allocation. Most zones are not affected since they do
not impose any specific limit on the maximum bucket size.
While here, remove the UMA_ZONE_MINBUCKET flag. It was unused and we
now have uma_zone_set_maxcache() to control the zone's cache size more
precisely.

r368355 removed the GNU_GREP_COMPAT knob (off by default) and forgot that
bsdgrep may be built/used for bootstrap on some systems.
All base uses should strive to use only POSIX-compliant expressions anyways
and we haven't had libregex by default here up to this point, so just don't
do that if we're bootstrapping.
Note that the resulting binary has the wrong `grep -V` information as it
falsely claims to be GNU compatible, but it is only for bootstrap.

this tries to rectify the problem using the utf8proc one (through
its C API) which would hopefully benefeat both FreeBSD and
