libspl: Provide platform-specific zone implementations

Browse Source 
FreeBSD has the concept of jails, a precursor to Solaris's zones, which
can be mapped to the required zones interface with relative ease.  The
previous ZFS implementation in FreeBSD did so, and we should continue
to provide an appropriate implementation in OpenZFS as well.

Move lib/libspl/zone.c into platform code and adopt the correct
implementation for FreeBSD.

While here, prune unused code.
