zfsloader(8) fails to probe a slice containing ZFS pool if its second sector
contains traces of BSD label (DISKMAGIC == 0x82564557).
Fix manual page to show working example erasing such traces.

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.

The current system is fragile and requires very careful layout of all
*_devdesc structures. It also makes it hard to change the base
devdesc. Take a page from CAM and put the 'header' in all the derived
classes and adjust the code to match.
For OFW, move the iHandle h_handle out of a slot conflicting with
d_opendata. Due to quirks in the alignment rules, this worked.
However changing the code to use d_opendata storage now that it's a
pointer is hard, so just have a separate field for it.
All other cleanups were to make the *_devdesc structures match where
they'd taken some liberties that were none-the-less compatible enough
to work.
Make sure { on the same line as struct for all struct *devdesc. Move
some type definitions to next to the dv_type define, since that's what
sets the d_type.
One does not simply convert to SUBDIR.yes in stand without making everything
else in the affected files SUBDIR.yes -- there are better ways to do this.
Use SUBDIR.${MK_*} where appropriate. r330248 eliminated most of the
offenders, sweep the rest under the rug.

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.
Curiously, changing whitespace seems to cause the md5 of the .o files to differ
these days hence the following testing strategy:
Tested by: objdump -d | md5 (both in-tree clang and lang/gcc6)
The Makefile gives the impression that ext2fs and msdos were excluded
(they weren't) and that you could exclude cd9660 and ufs support (you
couldn't). Allow those to be excluded.
We need to look, in the future, at trimming the number of supported
filesystems, and this will make that easier.
There's no reason to have multiple copies of lszfs and
reloadbe. Consolidate them into one location. Also ldi_get_size is the
same everywhere (except sparc64). Make it the same everywhere as the
common definition is more general and will work on spar64.
preference to LIBFICL{,32}. LIBFICL{,32} are now always defined, but
LDR_INTERP{,32} is defined empty when building w/o forth (aka the
simple interpreter) and defined to LIBFICL{,32} when we are building
forth.
I had thought that this would be useful. However it was committed too
late, and wound up being unused. It's in the way of future work now,
so retire it rather than bring it forward.
MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the
same, so set them in defs.mk. MAN= is common, so set it here too.
This removes a lot of boring repetition from the Makefiles that added
almost no value.
removing this argument, and expanding when rc is NULL. This
effectively completes the back out of custom scripts for tftp booted
loaders from r269153 that was started in r292344 with the new path
tricks that obsoleted it.

HELP_FILES is a loader only thing, so move it to loader.mk. Only
generate the help file if HELP_FILES is defined. Adjust Makefiles to
new convention. Fix a few cases where ${.CURDIR}/ was missing
resulting in missing bits from the help files.

weren't needed, and their existance interfered with things in subtle
ways. One of these subtle ways was that malloc could be different
based on what files were included when (even within the same .c file,
it turns out). Move to a single malloc implementation as well by
adding the calls to setheap() to gptboot.c and zfsboot.c. Once upon a
time, these boot loaders strove to not use libstand. However, with the
proliferation of features, that striving is too hard for too little
gain and lead to stupid mistakes.
This fixes the GELI-enabled (but not even using) boot environment. The
geli routines were calling libstand malloc but zfsboot.c and gptboot.c
were using the mini libstand malloc, so this failed when we tried to
probe for GELI partitions. Subtle changes in build order when moving
to self-contained stand build in r326593 toggled what it used from one
type to another due to odd nesting of the zfs implementation code that
differed subtly between zfsloader and zfsboot.

temporary workaround. This fixes zfs booting generally, but breaks all
GELI booting by default. Add note to UPDATING to this effect. When the
GELI issues are resolved, this will be reverted.
Don't print when we can't find a file. Copy it instead to the error
buffer. Higher level routines determine if it's appropriate to print
the error message.
Also, remove dead code (labeled bogusly lost functionality) since we
never used that functionality. Remove unused arg from interact() too.

Previous to the switch from sys/boot to stand/ zfsboot (used for MBR) did
not support GELI. Now that it is compiled with GELI, it is running out of
space.
zfsldr (which loads zfsboot) was modified to load 256kb in r304321
Default WARNS to 0 still, since there's still some warnings on other

Remove the now-useless dependency on ufsread.c. In some cases, it was
on the wrong file. But in all cases, we now automatically generate
.depend files, so we don't need it explicitly.

HAVE_GPT isn't currently a thing, but HAVE_GELI is. Replace the former
with the latter and remove util.o from the build list (it's picked up
from libsa/libsa32, and that's OK).

simd / no float stuff is centeralized here. Also centralise
-ffreestanding since it is specified everywhere.
This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
in CFLAGS_NO_SIMD should fix building for newer machines (eg with
CPUTYPE=haswell) where clang was generating avx2 instructions.
