769bad9f8a Add chain loader support for loader
Implement simple chain loader in loader; this update does add chain command,
taking device or file as argument to load and start new boot loader.

In case of BIOS, the chain will read the boot block to address 0000:7c00 and
jumps on it. In case of UEFI, the chain command is to be used with efi
application, typically stored in EFI System Partition.

The update also does add simple menu entry, if the variable chain_disk is set.
The value of the variable chain_disk is used as argument for chain loading.

4c7008824b Switch the example name for variables controlling loading memory images
in /boot/defaults/loader.conf to something that's actually commonly used,
"mdroot".  It's arbitrary, but it's easier to find this way.

a7dc31283a Remove the NATM framework including the en(4), fatm(4), hatm(4), and
patm(4) devices.

Maintaining an address family and framework has real costs when we make
infrastructure improvements.  In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).

With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.

Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021.  Improvements to the code in FreeBSD 11 are
certainly welcome.

150890b0c6 Replace the RC4 algorithm for generating in-kernel secure random
numbers with Chacha20. Keep the API, though, as that is what the
other *BSD's have done.

Use the boot-time entropy stash (if present) to bootstrap the
in-kernel entropy source.

d124e3965a loader.efi environment related cleanups
Since we have dedicated libefi/env.c file for variable support, the following
changes are done:

Simple cstyle changes in env.c
Moved efi variable related commands from loader/main.c to libefi/env.c
Did create function to set "efi-version" environment variable in env.c.

This function does serve two purposes: for first a  small clean up of the
loader main(), and for second, it does replace the otherwise unused
efi_variable_support hack.
A bit of cleanup of ficl backend functions. The TEST_MAIN has no meaning,
and removed few memory leaks.

The forth code is updated to use "efi-version" variable, instead of ficl
environment check.

b6110871b5 Preliminary support for EFI in boot loader. Define efi-boot forth
environment variable to allow conditional compilation based on EFI
being present or not. Provide efi-setenv, efi-getenv, and
efi-unsetenv, though those need improvement. Move the efi definition
to libefi (but include a reference so they get included).

0b1c7ee322 Create a hook 'post-initialize' for people that want to define
something (perhaps in loader.rc.local) that can read in .conf files
after all the other .conf files have been read and override settings
in them. This is quite handy if the .conf file name is determined
while the loader is running, but might be generically useful for other
things. If this hook exists, call it, otherwise don't do anything.

Doing it in these functions ensures that this file is reliably
read. It also works around a defect in forth where s" isn't allowed
outside a function (well, in a compile context) leading to gross
workarounds if one were to hack loader.rc like:

: maybe-some-func s" some-func" sfind if execute else drop then ;
maybe-some-func

which somehow seems worse. Though I'm sure there's some clever forthy
way of doing that with a macro.

29a46b5320 Remove supposition comment that code would better live elsewhere.
Thinking this through, and looking at process_assignment, I believe
moving the code would be wrong considering that set_conf_files is
called in one condition while set_nextboot_conf is guarded by a
different condition of having nextboot_enable="YES". So these must
stay separated and not combined.

b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

affc4a4bff Improve support for blacklisting bad memory locations. The user can supply
a text file with a list of physical memory addresses to exclude, and have it
loaded at boot time via the provided example in loader.conf.  The tunable
'vm.blacklist' remains, but using an external file means that there's no
practical limit to the size of the list.  This change also improves the
scanning algorithm for processing the list, scanning the list only once
instead of scanning it for every page in the system.  Both the sysctl and
the file can be unsorted and contain duplicates so long as each entry is
numeric (decimal or hex) and is separated by a space, comma, or newline
character.  The sysctl 'vm.page_blacklist' is now provided to report what
memory locations were successfully excluded.

ea1401b9a9 Fix a bootlock condition if/when loader_logo is set in loader.conf(5)
NB: This deeply effected HardenedBSD which had a default value set.

Embarassingly, I allowed the `type' primitive to be passed -1/-1 for
c-addr/u stack input (the effect of which is to pull INT_MAX bytes
from character address negative one in which hilarity ensues over a
black screen in full-on bootlock). Much thanks to Shawn Webb [lattera]
for helping me diagnose.

NB: The mode-ending revisions were initially suspected (and reverted)
but proved to be a red-herring. Proper mode endings will be returning.
