GPT scheme. UEFI needs to know the unique partition GUID
with GPT, which changes each time. Specifically, the QEMU
EFI BIOS file has this hard-coded.[1]
Since the GPT labels are now unavailable, unconditionally
label the root filesystem as 'rootfs' with newfs(8), since
it does not hurt anything anywhere else. For the arm64 case,
'/' is mounted from /dev/ufs/rootfs; for all other VM images,
'/' is mounted from /dev/gpt/rootfs.
Unfortunately, since the /dev/gpt/swapfs label is also lost,
set NOSWAP=1 for the arm64/aarch64 images. This is temporary,
until I figure out a scalable solution to this. But, a certain
piece of softare was written "very fast", and ended up living
for 15 years. We can deal with this for a week or so.

building FreeBSD/arm64 VM images and memstick.img installation
medium:
r281786, r281788, r281792:
r281786:
Add support for building arm64/aarch64 virtual machine images.
r281788:
Copy amd64/make-memstick.sh to arm64/make-memstick.sh for
aarch64 memory stick images.
Although arm64 does not yet have USB support, the memstick
image should be bootable with certain virtualization tools,
such as qemu.
r281792:
Add a buildenv_setup() prototype, intended to be overridden as
needed.
For example, the arm64/aarch64 build needs devel/aarch64-binutils,
so buildenv_setup() in the release.conf for this architecture
handles the installation of the port before buildworld/buildkernel.

copy the userland from one md(4)-mounted filesystem to a clean
filesystem to prevent remnants of files that were added and
removed from resulting in an unclean filesystem. When newfs(8)
creates the first filesystem with journaled soft-updates enabled,
the /.sujournal file in the new filesystem cannot be overwritten
by the /.sujournal in the original filesystem.
To avoid this particular error case, do not enable journaled
soft-updates when creating the md(4)-backed filesystems, and
instead use tunefs(8) to enable journaled soft-updates after
the new filesystem is populated in vm_copy_base().
While here, fix a long standing bug where the build environment
/boot files were used by mkimg(1) when creating the VM disk
images by using the files in .OBJDIR.

* Remove vm_umount_base function which is currently unused.
* Add umount_loop function which loops attempting to unmount one filesystem.
* Replace calls to umount with calls to umount_loop.
* Don't attempt to unmount ${DESTDIR}/dev if it isn't mounted.
The looping is necessary because sometimes umount fails due to filesystems
being busy. The most common cause of such busyness is periodic(8) jobs
running `find / ...`.

a new filesystem before packaging it into a disk image. This prevents
"remnants" of deleted files from showing up in the VM images, and reduces
their compressed size (by about 10% for the cloudware images) as a result.

post-install packaging cloud provider images.
Add a 'gce-package.sh' script to generate the final output
image ready for upload to the GCE platform. Right now, this
is the only image that has a specific output format (GNU-tar),
and this implementation is expected to be temporary.
This is not directly connected to the other release targets.

Add CLOUDINSTALL variable to automatically generate the
actual list of install targets. While here, rename the
cloud-specific names from 'vm-' to 'cw-' to avoid naming
collisions.
Add AZURE_DISK, GCE_DISK, and OPENSTACK_DISK output file
variables.
Add 'cloudware-install' to the 'install' target.

Separately document multi-threaded support to keep the
version update separate, so it remains correct if xz(1)
is updated again.
Sponsored by: The FreeBSD Foundation
libarchive(3) doesn't support the new liblzma API yet, but this change
allows us to enable multi-threaded xz compression.
``make release'' should now finish in half the time on a machine with
several cores and fast disks (our typical build server).
This behaviour only applies when building a release and it doesn't
affect buildworld/installworld. To disable threaded xz compression,
set XZ_THREADS=1.
