Enable LLVM_BINUTILS by default

Starting in 2014 FreeBSD migrated from GNU binutils to ELF Tool Chain
tools. At that time there were no usable LLVM versions of those tools,
but they have been developing rapidly since then. Migrate to LLVML's
tools for both functionality and maintainability reasons.

This will eventually support the use of link-time optimization (LTO) in
the FreeBSD base system. LTO runs optimization passes over the entire
executable (or library) at link time and thus allows for more effective
optimization than when performed on individual compilation units.

When using LTO object files (.o) including those contained in static
library archives (.a) contain LLVM IR bitcode rather than target
object code. This means that utilities that operate on object files
need to support LLVM IR.

As with ELF Tool Chain the LLVM tools aim for command line and output
format compatibility with GNU binutils, although there are a few minor
differences. Where these cause a material issue (breaking a port or
eliminating required functionality) we can submit LLVM bugs and work
on patches.

usr.bin/bc: remove OpenBSD derived bc and dc commands

In 2020, an improved implementation of the bc and dc commands
developed by Gavin D. Howard has been imported into FreeBSD.
It has replaced the OpenBSD-derived versions of these commands
in all currently supported FreeBSD releases.

The OpenBSD versions could still be built using the WITHOUT_GH_BC
option. There have been no reports of problems or unexpected
deviations from the OpenBSD version for some time, therefore
keeping the OpenBSD version is no longer required in FreeBSD.

This commit removes the option to build the OpenBSD version and
corresponding source files from -CURRENT. No MFC is planned, all
currently released FreeBSD versions should retain the build option.

The WITHOUT_GH_BC option is no longer accepted and will cause
make buildworld to fail.

rc: Remove rc_fast_and_loose

The rc_fast_and_loose variable allowed rc(8) to start services
by sourcing them into rc's own shell environment. Normally, each rc
service script is started by being sourced into its own subshell
instead. The feature was meant to speed up rc(8) by avoiding the extra
forking necessary to spawn subshells.

In practice, the feature has been broken for a long time now. One of the
reasons is that some rc service scripts call the exit builtin to return
non-zero error codes, which not only terminates the service subshell
but also rc(8) when rc_fast_and_loose is enabled. For example,
a system running any of the supported FreeBSD releases
with rc_fast_and_loose=yes would abort rc(8) as early as rc.d/hostid,
due to an "exit 0".

Fixing rc_fast_and_loose support would require rewriting some rc scripts
to support being sourced directly into rc(8) process. This would muddy
the code base and also would prove difficult to maintain long term
as this is simply not how rc(8) users write scripts. The potential
performance benefits are unlikely to be significant even for use cases
such as Morello under qemu.

Instead, remove support for rc_fast_and_loose completely from rc(8)
and inform users about the change.

UPDATING: Add belated note about hints for old-school ISA devices

Back in July, jhb started a cleanup of our hints. We've removed several
that have been a problem for a long time (including some that had
workarounds for VM images). We've also moved uarts to ACPI only, so they
act more like wiring than enumeration hints. Add a note about this and
ways you can find if your system is affected. Old APU1 routers with
coreboot are affected, but newer APU2 devices are not. Others likely are
as well. The affected systems will be primarily very ancient systems
that pre-date ACPI (i586 arch pentium and older typically), as well as
some older coreboot and similar non-conventional boot firmware setups
(primarily in the embedded space). FreeBSD 15 will require ACPI or
PNPBIOS enumeration for everything by default, so any non-enumerated
devices via these means will require hints. Add notes on how to grep
for affected systems before upgrading.

Do not clean (in buildworld/buildkernel) by default

As discussed on the freebsd-arch mailing list[1]. For historical
reasons FreeBSD's buildworld and buildkernel targets started by cleaning
the object tree, for traditional (non-metamode) builds.

Cleaning is not necessary when dependencies are properly tracked, and we
have a somewhat kludgey script[2] to handle some known cases where deps
were mishandled by traditional builds. Be consistent with the vast
majority of open source build systems by default, and do not clean at
the beginning of buildworld or buildkernel.

Users may set WITH_CLEAN in src.conf(5) to restore the previous
behaviour, or run `make cleanworld` and/or `make cleankernel` before
starting a build.

stand/lua: always allow overriding with local config files

Loader now also read configuration files listed in local_loader_conf_files.
Files listed here are the last ones read. And /boot/loader.conf.local was
moved from loader_conf_files to local_loader_conf_files leaving only
loader.conf and device.hints in loader_conf_files by default.

The idea is to ensure local_loader_conf_files, i.e., /boot/loader.conf.local,
can always be used to override other user defined settings.

So the sequencing is now as follow:

1. Bootstrap:
/boot/defaults/loader.conf

2. Read loader_conf_files files:
/boot/device.hints
/boot/loader.conf

3. Read loader_conf_dirs files:
/boot/loader.conf.d/*.conf

4. And finally, rread local_loader_conf_files files:
/boot/loader.conf.local
