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: upstream signal implementation

Upstream the bsd-user fork signal implementation, for the most part. This
series of commits represents nearly all of the infrastructure that surround
signals, except the actual system call glue (that was also reworked in the
fork and needs its own series). In addition, this adds the sigsegv and sigbus
code to arm. Even in the fork, we don't have good x86 signal implementation,
so there's little to upstream for that at the moment.

bsd-user's signal implementation is similar to linux-user's. The full context
can be found in the bsd-user's fork's 'blitz branch' at
https://github.com/qemu-bsd-user/qemu-bsd-user/tree/blitz which shows how these
are used to implement various system calls. Since this was built from
linux-user's stack stuff, evolved for BSD with the passage of a few years, it
no-doubt missed some bug fixes from linux-user (though nothing obvious stood out
in the quick comparison I made). After the first round of reviews, many of these
improvements have been incorporated.

bsd-user: arm (32-bit) support

This series of patches brings in 32-bit arm support for bsd-user. It implements
all the bits needed to do image activation, signal handling, stack management
and threading. This allows us to get to the "Hello World" level. The arm and x86
code are now the same as in the bsd-user fork. For full context, the fork is at
https://github.com/qemu-bsd-user/qemu-bsd-user/tree/blitz (though the the recent
sig{bus,segv} needed updates are incomplete).

v5 changes:
o Moved to using the CPUArchState typedef and move
set_sigtramp_args, get_mcontext, set_mcontext, and
get_ucontext_sigreturn prototypes to
bsd-user/freebsd/target_os_ucontext.h
o Fix issues with arm's set_mcontext related to masking
and remove an unnecessary check.

We're down to only one hunk needing review:
bsd-user/arm/target_arch_signal.c: arm set_mcontext

Warnings that should be ignored:
o make checkpatch has a couple of complaints about the comments for the
signal trampoline, since it's a false positive IMHO.

bsd-user/arm/target_arch_cpu.h: Implement trivial EXCP exceptions

Implement EXCP_UDEF, EXCP_DEBUG, EXCP_INTERRUPT, EXCP_ATOMIC and
EXCP_YIELD. The first two generate a signal to the emulated
binary.

Implement EXCP_UDEF, EXCP_DEBUG, EXCP_INTERRUPT, EXCP_ATOMIC and
EXCP_YIELD. The first two generate a signal to the emulated
binary. EXCP_ATOMIC handles atomic operations. The remainder are fancy
nops.
