bsd-user mmap and exec branches from gsoc

This pull request represents the mmap and exec changes from Karim Taha
for his GSoC project.

They represent all the mmap and exec related system calls and get bsd-user to
the point that a dynamic hello-world works (at least for armv7).

There are a couple of patch check errors, but they are the lessor evil: I made
purposely bad style choices to ensure all the commits compiled (and i undid the
style choices in subsequent commits).

I pushed an earlier version to gitlab, and all but the riscv64 pipelines were
green. Since bsd-user doesn't change anything related to ricsv64 (there's no
support in qemu-project repo, though we do have it in the bsd-user fork: coming
soon).

I think this is good to go.

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 pull request: merge dependencies for next architectures

Merge the dependencies for arm, aarch64, and riscv64 architectures. This joins
together two patch series:

[PATCH v2 00/15] bsd-user: misc cleanup for aarch64 import

Prepare for aarch64 support (the next architecture to be upstreamed). As the
aarch64 emulation is more complete, it relies on a number of different items.
In some cases, I've pulled in the full support from bsd-user fork. In other
cases I've created a simple stub (as is the case for signals, which have
independent changes pending, so I wanted to be as minimal as possible. Since
all pre-12.2 support was purged from the bsd-user fork, go ahead and remove it
here. FreeBSD 11.x goes ouft of support at the end of the month. Remove what
little multi-version support that's in upstream.

and

[PATCH v3 0/9] bsd-user mmap fixes
This series synchronizes mmap.c with the bsd-user fork. This is a mix of old bug
fixes pulled in from linux-user, as well as some newer fixes to adress bugs
found in check-tcg and recent FreeBSD developments. There are also a couple of
style commits. Updated to migrate debugging to qemu_log.

as well as a couple of minor rebase tweaks. In addition, the next two
architectures I plan on upstreaming (arm and riscv64) also have their prereqs
satisfied with this request.

v2: Remove accidental module regression in patch 7 and try again.
