891b84a3aa Invent new LDR_INTERP for the loader interpreter to use. Use this in
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.

b28421d5f1 These 4th words were an attempt to allow integration into the boot
loader scripts. However, that path won't be taken after all it
seems. Remove this code before it decays into uselessness. Also remove
build dependencies on forth no longer needed.

8299b37f85 Centralize several variables.
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.

8a613444b5 stand/fdt: Consolidate overlay handling a little further
This should have been done as part of r327350, but due to lack of foresight
it came later. In the different places we apply overlays, we duplicate the
bits that check for fdt_overlays in the environment and supplement that with
any other places we need to check for overlays to load. These "other places"
will be loader specific and are not candidates for consolidation.

Provide an fdt_load_dtb_overlays to capture the common logic, allow passing
in an additional list of overlays to be loaded. This additional list of
overlays is used in practice for ubldr to pull in any fdt_overlays passed to
it from U-Boot environment, but it can be used for any other source of
overlays.

These additional overlays supplement loader.conf(5) fdt_overlays, rather
than replace, so that we're not restricted to specifying overlays in only
one place. This is a change from previous behavior where loader.conf(5)
supplied fdt_overlays would cause us to ignore U-Boot environment, and this
seems nonsensical- user should have sufficient control over both of these
aspects, or lack of control for good reasons.

A knob could be considered in the future to ignore U-Boot supplied overlays,
but the supplemental treatment seems like a good start.

When building loader bits, lld fails with the following error:

96c4f2c537 Check the return value from utf8_to_ucs2 instead of whether or not uv
is NULL. That's more correct and doesn't depend on the error behavior
of utf8_to_ucs2. In practice, we'll never see this though since we
pass utf8_to_ucs2 a well formed string.

2c18ede691 Fix booting on some arm64 systems after r327879 by fixing the call to
utf8_to_ucs2 in boot1.efi. We need to initialise the ucs2 output string
so it will allocate space, and use the return value to determine if the
call was successful.

1d28802f0c Allow this file to be included
Use simple "foo" rather than "${.CURDIR}/foo" to include Makefile.fat
since the former works when including this Makefile from else
where. Also, use full path from ${BOOTSRC} to the FAT templates for
similar reasons. It doesn't change anything in base FreeBSD, but
allows us to have a custom boot1.efi more easily (though that will be
short-lived for us, it may also be helpful for others).

06d6750e0d stand/fdt: Consistently apply fdt_overlays
Overlays were previously not applied when U-Boot provides FDT or EFI
provides FDT, only when we load FDT from /boot/dtb given name from U-Boot.

Make all three paths lead to loading fdt_overlays and applying them, so that
fdt_overlays can be expected to Just Work.

5e6e2d38c1 [boot/efi] scan all display modes rather than sequential try-fail way
This patch allows to scan all display modes in boot1 as loader does.

Before system tried to select optimal display mode by sequential scan of
modes and if error then stop scanning. This way is not good, because
if mode N is not present, mode N+1 may exist.

In loader we use conout->Mode->MaxMode to identify maximum number of modes.
This commit is to use same way in boot1 as in loader.

6bc860372d Interact is always called with NULL. Simplify code a little by
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.

f38658e140 Prefer stdint.h to inttypes.h since the added prototypes form the
latter aren't used. Prefer sys/link_elf.h to link.h so we're only
dependent on the kernel tree. The default installation of link.h just
includes this file, and any benefit from that is outweighed by the
hassle it causes. This reduces the footprint of files needed from the
system includes (or sysroot in buildworld).

e4f6a1bfa3 loader.efi: efipart should exclude iPXE stub block protocol
iPXE does insert stub  BLOCK IO protocol handle to rework other issues,
this handle is not usable as it does not provide actual implementation.

We can detect this situation by checking and validating the BlockSize
property, so this update does make sure we have BlockSize at least 512B
and its value is power of 2.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
