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, armv7 and riscv64 patch sets will be published soon after some of
the dust settles.

v2: Added Phillippe's take, as endorced by Paolo, on how to filter *-user.
    Added qemu_log_mask() to stubbed out signal queueing routines

(hopefully I've done the pull into my tree correctly)
