e307eb94ae loader: zfs should support bootonce an nextboot
bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.

By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.

By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.

bootonce dataset name is recorded in boot pool labels, bootenv area.

in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.

bootonce and nextboot features are usable in both UEFI and BIOS boot.

To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).

At this time, only lua loader is updated.

2de5a21edc loader_4th: menu items need to reset color attribute, not switch to white
Forth menu kernel and BE entries, instead of resetting the color attribute,
are switching to white color.

bb7b569d36 loader: Respect loader_color=YES for serial consoles
It's not uncommon these days for the terminals attached to serial consoles
to support ANSI escape sequences. However, we assume escape sequences may
break some serial consoles and default to not using them when boot_serial or
boot_multicons (or if console contains "comconsole" in the forth loader) for
broader compatibility. We also have loader_color which can be explicitly set
to "NO" to disable the use of ANSI escape sequences.

The problem is that loader_color=YES gets ignored when boot_serial=YES or
boot_multicons=YES (or when console contains "comconsole" in the forth
loader).

To fix, the existing default behavior remains unchanged when loader_color is
unset, loader_color=NO explicitly disables the use of ANSI escape sequences
still, and the change is that loader_color=YES can now be used to explicitly
allow ANSI escapes when a serial console is enabled.

56758831fe loader: use teken teminal emulator for x86 and uefi
Replace mini cons25 emulator with teken, this does enable us proper console
terminal for loader and will make it possible to implement different
back end callbacks to draw to screen.

At this time we still only "draw" in text mode.

52467047aa Regularize the Netflix copyright
Use recent best practices for Copyright form at the top of
the license:
1. Remove all the All Rights Reserved clauses on our stuff. Where we
   piggybacked others, use a separate line to make things clear.
2. Use "Netflix, Inc." everywhere.
3. Use a single line for the copyright for grep friendliness.
4. Use date ranges in all places for our stuff.

fb205d37d7 forthloader: Remove "EFI boot environment message"
Contrary to what the message says, this is not only executed in an EFI
context- it provides functions for use in an EFI environment. I don't think
there's much reason to broadcast this fact when we haven't in the past, so
just remove it.

9afece1e2f forthloader: Don't break BIOS boots...
I thought I tested this scenario, but clearly I failed to. =(

BIOS boots won't have efi-autoresizecons, so trying to use it as a forth
word fails during include. Use evaluate on "efi-autoresizecons" as a string
instead to move any potential errors to runtime- safely after we've already
checked that we're booting UEFI.

5ef2174a50 Forth version of EFI autoresizing
r331321 delegated autoresizing to an efi-autoresizecons command that
currently is expected to be done in forth/lua prior to drawing anything
useful.

Add the Forth version of the lua addition in r331321, hook efi.4th up to be
installed.

efiboot? was written by dteske@; anything outside of that may be blamed on
me.

0c38f15ac7 Add NO_OBJ to those directories that don't make anything.
For directories that don't many anything, add NO_OBJ=t just before we
include bsd.init.mk. This prevents them from creating an OBJ
directory. In addition, prevent defs.mk from creating the machine
related links in these cases. They aren't needed and break, at least
on stable, the read-only src tree build.

74bb0b0e9a Retire pnp.4th and the code needed only for 4th words used here.
This has never been installed. It was added to the tree disconnected
to the build in FreeBSD 5 (17 years ago) and has never been used as
far as I can tell. The desired improvements never really happened
(despite a couple minor cleanups along the way). It's relevance is
long past, so better to retire it.

db180ae55c stand: Add /boot/overlays to allow separation of overlays from base FDT
This matches directory structure used commonly in Linux-land, and it's
cleaner than mixing overlays into the existing module paths. Overlays are
still mixed in by specifying fdt_overlays in loader.conf(5).
