bsdinstall/zfsboot GPT+BIOS+GELI installs now make use of GELIBOOT

In this configuration, a separate bootpool is not required.
This allows ZFS Boot Environments to be used with GELI encrypted ZFS pools.

Support for GPT+EFI+GELI is planned for the future.

Fix default ZFS layout to work better by default with sysutils/beadm

The root file system is mounted early via vfs.root.mountfrom.
The canmount=noauto property only affects the zfs rc.d script.
This ensures that the 'default' BE is not mounted overtop of another BE when
one is selected from the beastie menu

Never 4k align the MBR bootpool because zfsldr can not deal with a gap

Never 4k align the MBR bootpool because zfsldr can not deal with a gap

If the bootpool does not start at the first sector of the BSD partition
then zfsldr seeks to the wrong offset inside the ZFS vdev label, and is
unable to find zfsboot, so the system does not boot

If 4k alignment is requested, align the BSD partition in the MBR table,
and align the swap and data pool, but the bootpool must start at sector 1

While here, if 4k alignment is requested, disable MBR CHS alignment, as
this results in not-4k aligned partitions.
