The FreeBSD linux/compiler.h in OpenZFS was copied from a very old
version of FreeBSD's linuxkpi's linux/compiler.h. There's no need for
this duplication. Use FreeBSD's linuxkpi version instead, and provide
zfs_fallthrough to augment it (it's all that's needed). Use #pragma once
to avoid naming issues for guard variables. Since this is a complete
rewrite, use my copyright here (the original code in FreeBSD still
credits everybody). This works back at least to FreeBSD 12.4, which
is not out of support, and all newer releases.
Remove extra copies of macros that were defined elsewhere, but are now
properly defined in LinuxKPI so are redundant.

We inherited membar_consumer() and membar_producer() from OpenSolaris,
but we had replaced membar_consumer() with Linux's smp_rmb() in
zfs_ioctl.c. The FreeBSD SPL consequently implemented a shim for the
Linux-only smp_rmb().
We reinstate membar_consumer() in platform independent code and fix the
FreeBSD SPL to implement membar_consumer() in a way analogous to Linux.

As of the Linux 5.9 kernel a fallthrough macro has been added which
should be used to anotate all intentional fallthrough paths. Once
all of the kernel code paths have been updated to use fallthrough
the -Wimplicit-fallthrough option will because the default. To
avoid warnings in the OpenZFS code base when this happens apply
the fallthrough macro.

In FreeBSD, there are three compile environments that are supported:
user land, the kernel and the bootloader / standalone. Adjust the
headers to compile in the standalone environment. Limit kernel-only
items from view when _STANDALONE is defined.

Reduce the usage of EXTRA_DIST. If files are conditionally included in
_SOURCES, _HEADERS etc, automake is smart enough to dist all files that
could possibly be included, but this does not apply to EXTRA_DIST,
resulting in make dist depending on the configuration.
Add some files that were missing altogether in various Makefile's.

Add the FreeBSD platform code to the OpenZFS repository. As of this
commit the source can be compiled and tested on FreeBSD 11 and 12.
Subsequent commits are now required to compile on FreeBSD and Linux.
Additionally, they must pass the ZFS Test Suite on FreeBSD which is
being run by the CI. As of this commit 1230 tests pass on FreeBSD
and there are no unexpected failures.
