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).

This doesn't build on openbsd at the moment, and this could

we refactor to support OpenBSD/NetBSD again, drop it here.

Update target_arch_elf.h to remove thread_init. Move its contents to
target_arch_thread.h and rename to target_thread_init(). Update
elfload.c to call it. Create thread_os_thread.h to hold the os specific
parts of the thread and threat manipulation routines. Currently, it just
includes target_arch_thread.h. target_arch_thread.h contains the at the
moment unused target_thread_set_upcall which will be used in the future
when creating actual thread (i386 has this stubbed, but other
architectures in the bsd-user tree have real ones). FreeBSD doesn't do
AT_HWCAP, so remove that code. Linux does, and this code came from there.
These changes are all interrelated and could be brokend down, but seem
to represent a reviewable changeset since most of the change is boiler
plate.
