[00/14] bsd-user: misc cleanup for aarch64 import

Message

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.

The aarch64 patch set will be published soon after some of the dust settles.
