bsd-user: Misc changes for 9.1 (I hope)

V2: Add missing bsd-user/aarch64/target.h

This patch series includes two main sets of patches. To make it simple to
review, I've included the changes from my student which the later changes depend
on. I've included a change from Jessica and Doug as well. I've reviewed them,
but more eyes never hurt.

I've also included a number of 'touch up' patches needed either to get the
aarch64 building, or to implmement suggestions from prior review cycles. The
main one is what's charitably described as a kludge: force aarch64 to use 4k
pages. The qemu-project (and blitz branch) hasn't had the necessary changes to
bsd-user needed to support variable page size.

Sorry this is so late... Live has conspired to delay me.

bsd-user: Simplify the implementation of execve

This removes the logic which prepends the emulator to each call to
execve and fexecve. This is not necessary with the existing
imgact_binmisc support and it avoids the need to install the emulator
binary into jail environments when using 'binmiscctl --pre-open'.

Merge tag 'bsd-user-mmap-pull-request' of https://gitlab.com/bsdimp/qemu into staging

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.
