64c33f341f Minor flags cleanup
Move kernel includes and libsa includes together at the top of defs.mk
Move all machine specific defines from Makefile.inc to their friends
in defs.mk.
Add comments and remove now useless junk after the move.

ecc59efa8f Remove stale dependency on ufsread.c
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.

486f895a05 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.

90013f9fc4 Use const pointers to avoid casting away constness.
The host_open interface was a legitimate mismatch to the userboot
function, while the other pointers didn't need to be non-const.

This makes the powerpc warning free again.

fab6aff4e0 Modify all FreeBSD bootloaders on PowerPC AIM (Book-S) systems to pass a
magic number to the kernel in r7 rather than the (currently unused and
irrelevant) width of the metadata pointer, which I believe was intended
for a never-used approach to the 64-bit port. This enables the kernel,
in a future commit, to switch on the cookie to distinguish a real
metadata pointer from loader(8) from garbage left in r6 by some other
boot loader.

291ce17bc8 Mark the func pointer as __dead2. It looks up loader_main, which
either aborts or exits, but never returns. Tag it as a non-returning
function rather than supply a bogus return(0) at the end of main.

7f37401396 Fix theoretical integer overflow issues. If the product here is
greater than 2^31-1, then the result will be huge. This is unlikely,
as we don't support that many sections, but out of an abundace of
caution cast to size_t so the multiplication won't overflow
mysteriously when size_t is larger than 32-bits. The resulting code
may be a smidge larger, but this isn't super-space critical code.

8ae2696ae5 loader.efi: efipart does not recognize partitionless disks
Rework the block device handle check to allow more robust device
classification. This is mostly usability issue - it can be quite confusing
for user when no disks are listed with lsdev.

Add more comments about what and why is done.

432a653659 Unbreak riscv build in universe.
riscv doesn't have -msoft-float. For the moment, just don't add
anything. There's no /boot/loader or other bootstrap contained in the
tree for riscv*. However, with real hardware coming next year, there
are plans for one, so keep building at least a minimal libsa and
ficl to prevent bitrot.

249ed0c475 Fix gptzfsboot for cases with GELI.
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).

f097f35b37 Move some more common stuff up to Makefile.inc. In particular, the no
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.
