[00/14] bsd-user: Misc changes for 9.1 (I hope)

Message

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.
