Prior to bringing efi into the system, amd64 systems were building
32-bit ficl only, while userboot required the 64-bit one. However,
with efi, we now build both. userboot can and should use the one we
build for the main tree (in fact, it has been for a while, though I
didn't check to see if that was an intentional change before, or an
accidental one in my cleanup). Eliminate the extra copy (and build
time) for userboot.

Modelled after the i386 zfsloader. However, with no
2nd stage zfsboot to search for a bootable dataset,
attempt a ZFS boot if there is more than one ZFS
dataset found during the disk probe.
sys/boot/userboot/zfs
- build the ZFS boot library
sys/boot/userboot/userboot/
conf.c
- Add the ZFS pool and filesystem tables
devicename.c
- correctly format ZFS devices
main.c
- increase the size of the libstand malloc pool
to account for the increased usage from ZFS buffers
- probe for a ZFS dataset, and if one is
found, attempt to boot from it.
usr.sbin/bhyveload/bhyveload.c
- allow multiple invocations of the '-d' option
to specify multiple disks e.g. a raidz set.
Up to 32 disks are supported.
Tested with various combinations of GPT, MBR, single
and multiple disks, RAID-Z, mirrors.
