Merge remote-tracking branch 'remotes/bsdimp/tags/bsd-user-preen-2022q1-pull-request' into staging

bsd-user: Prepare for future upstream of system calls.

Merge remote-tracking branch 'remotes/bsdimp/tags/bsd-user-preen-2022q1-pull-request' into staging

bsd-user: Prepare for future upstream of system calls.

This series of patches does three things.

First, it starts to give up on the idea that you can run FooBSD binaries on
BarBSD. They are too different to make that happen any time soon, though I've
kept the support for Net/OpenBSD, even though they haven't built. We'll need a
lot of work to make that happen, though, and I need to simplify to get things
upstream.

Second, it starts to move some of the ifdef trees into target.h.

Third, it starts to upstream bsd-file.h, but the remainder of the file in the
bsd-user fork had some issues that will be resolved before next quarter's
update.

bsd-user: introduce target.h

Create target.h. This file is intended to be simple and describe basic
things about the architecture. If something is a basic feature of the
architecture, it belongs here. Should we need something that's per-BSD
there will be a target-os.h that will live in the per-bsd directories.

Define regpairs_aligned to reflect whether or not registers are 'paired'
for 64-bit arguments or not. This will be false for all 64-bit targets,
and will be true on those architectures that pair (currently just armv7
and powerpc on FreeBSD 14.x).
