Now that the minor issues preventing zfs.c from using CFLAGS_EARLY have
been fixed, use that mechanism like everything else that needs the
OpenZFS spl headers. This simplifies things somewhat. Update comments to
document why zfs.c is still special, though in different ways.
Note: We also use the fact that NEED_SOLARIS_BOOLEAN is only defined in
an environment where the solaris compat boolean stuff will be defined
prior to this point (eg, when we're building zfs.c in libsa), but not in
other environments (like when we're building mkimage and stand-alone
boot loaders that don't use libsa). These latter uses should be changed
to use the same ZFS compile env, but aren't as part of this commit.
This has to be done in the same change as the ZFS_EARLY change to not
break zfs.c building for one commit affecting bisectabiltiy.

Constrain CFLAGS for ZFS: don't add anything globally. Add the includes
to only the files that need them. Add -DHAS_ZSTD_ZFS to zfs.c (which
includes zfsimpl.c which includes zfssubr.c both of which need this
defined). Also add it to efi/boot1/Makefile since zfs_module.c also
includes zfsimple.c.

This fixes the build with MK_LOADER_ZFS=no. ZFS's Makefile.inc adds
these flags globally to CFLAGS when it should not. This masked the
problem because the tools/boot/universe.sh didn't build MK_LOADER_ZFS=no
as part of its regressions. Future work will also fix this.

Early in boot, we need to create the normal stdin/out/err env for the
boot loader to run in. To do that, we need to open the console and
duplicate the file descriptors which requires dup(2). Implement a

Linux's /dev/fd is implemented inside of /proc/self/fd, so we may need
to create a symlink to it early in boot. "/dev/fd" and "/dev/std*" might

Add the common O_ constants for the open, fcntl, etc system calls. They

Add the necessary glue to get blake3 building for the boot loaded as
well as connected to the ZFS system so it is useful.
On some platforms, we create references to blake3_sse2_impl and
blake3_sse41_impl ops structs to utilize SIMD. These aren't present on
x86 (since we dind't ask for them), but are on aarch64 with no
implementation. Since we don't want SIMD in the boot loader, have these
all return 'unsupported' always. This should be fixed upstream to allow
more flexibility in this selection, but for now we use this hack to not
modify the sys/contrib/openzfs with difficult to maintain hacks while
an upstreamable solution is found.

Makefile work and the aweful blake3_impl_hack.c.

sys/blake3.h is not safe to include in a standalone environment. It
assumes, unwisely, that there's only kernel or userland. The userland
choice is bad due to imperfections in how we handle stdlib.h in this
environment (we wind up including the host's stdlib.h, it expects a
standard FreeBSD setup which the gymnastics we've done to create a
OpenSolaris/Illumos-like environment interfere with). Thankfully, in
this case we can just pretend to be the kernel for a little bit by
defining _KERNEL and the undefing it after we exit.

There's a number of issues with including zfs_context.h from a
standalone environment. First, sys/uio_imp.h isn't at all safe for this
environment, so define its guard #defines so that its contents are
skipped. Next, there's a problem including string.h to get the mem*
routines, so just define them here. ZFS_MODULE_PARAM_ARGS isn't defined
properly. I had wanted to define it when I was upstreaming changes to
include/os/freebsd/spl/sys/zfs_context.h, but they ran into resistance
so I'm defining that here now (it is also defined in zstd_shim.c, but
that will disappear once the issues it works around are
cleared). Finally, sys/sysmacros.h has to be included now before
sys/atomic.h, but upstream includes it after so include it here so that
the guards make the out-of-order includes in upstream irrelevant.
