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.

In commit d8237b955528, as part of the deprecation of IPv4 address

hopefully be an error in the future."

As the warning has been included in releases from FreeBSD 13.1 on, and
sufficient time has passed, turn this into an error.

stand/lua: always allow overriding with local config files

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:

can do conditionals for things like this in the future.

This is at best a rapid-response stop-gap.
