makefs: Add ZFS support

This allows one to take a staged directory tree and create a file
consisting of a ZFS pool with one or more datasets that contain the
contents of the directory tree. This is useful for creating virtual
machine images without using the kernel to create a pool; "zpool create"
requires root privileges and currently is not permitted in jails.
makefs -t zfs also provides reproducible images by using a fixed seed
for pseudo-random number generation, used for generating GUIDs and hash
salts. makefs -t zfs requires relatively little by way of machine
resources.

The "zpool_reguid" rc.conf setting can be used to ask a FreeBSD guest to
generate a unique pool GUID upon first boot.

A small number of pool and dataset properties are supported. The pool
is backed by a single disk vdev. Data is always checksummed using
Fletcher-4, no redundant copies are made, and no compression is used.
The manual page documents supported pool and filesystem properties.

The implementation uses a few pieces of ZFS support from with the boot
loader, especially definitions for various on-disk structures, but is
otherwise standalone and in particular doesn't depend on OpenZFS.

This feature should be treated as experimental for now, i.e., important
data shouldn't be trusted to a makefs-created pool, and the command-line
interface is subject to change.

makefs: Fix warnings and reset WARNS to the default

Leave -Wcast-align disabled, at least for now, since there are numerous
instances of that warning in places where buffer pointers are cast to
pointers to various filesystem structures. Fixing this properly would
be too much work for too little gain.

makefs: add msdosfs (FAT) support

Add FAT support to makefs by copying some files from sys/fs/msdosfs/ and
updating others with changes from NetBSD.

The six files copied from sys/fs/msdosfs at r348251 and modified are:
denode.h direntry.h fat.h msdosfs_fat.c msdosfs_lookup.c msdosfsmount.h

I would prefer to avoid the duplication, but reluctance to doing so was
expressed in a previous review (D11197); for now copy the files and
revisit in the future.

Assign a random number to di_gen (for FFS), instead of extracting it
from struct stat. We don't necessarily have permissions to see the
generation number and the host OS may not have st_gen in struct stat
anyway. Since the kernel assigns random numbers, there's nothing
meaningful about the generation that requires us to preserve it when
the file system image is created. With this change, all generation
numbers come from random() and that makes it easier to add support
for reproducible builds at some time in the future (i.e. by adding
an argument to makefs that changes the behaviour of random() so that
it always returns 0 or some predictable sequence).
