MFC all change to makefs through r247052. Key functional changes
include:

r239562:
Add -p flag to create the image as a sparse file.

r242501:
If no contents keyword is specified, the default for files is
the named file.

r247041:
Add a -D flag that causes duplicate entries in an mtree manifest to be
treated as warnings rather than errors.

r247042:
Fix the -N option in manifest mode by using pwcache(3). This also
speeds up image creation appreciably.

r247043:
Allow '.' components in manifest paths. They are always the first
component of mtree -C and install -M output and are easily skipped.

r247052:
Support hardlinks in manifest files by the same logic as the treewalk
code.

MFC: r230795

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Add support for using mtree(5) manifest files to define the image
to be created. The support is based on mtree version 2.0, as used
in libarchive, but adds new features on top of it.

The current implementation is fully functional, but is envisioned
to grow at least the following additional features over time:
o Add support for the /include special command so that manifest
files can be constructed using includable fragments.
o Add support specifying a search path to locate content files.
o Content file filters: commands that provide file contents on
stdout.

The manifest file eliminates the need to first construct a tree
as root in order to create an image and allows images (releases)
to be created directly from object trees and/or source trees.

The dump, fsck_ffs, fsdb, fsirand, newfs, makefs, and quot utilities
include sys/time.h instead of time.h. This include is incorrect as
per the manpages for the APIs and the POSIX definitions. This commit
replaces sys/time.h where necessary with time.h.

The commit also includes some minor style(9) header fixup in newfs.

This commit is part of a larger effort by Garrett Cooper started in
//depot/user/gcooper/posix-conformance-work/ -- to make FreeBSD more
POSIX compliant.

fix 64-bit build

import netbsd makefs tool

add properties and FreeBSD id's

turn warnx into a debug msg

another nbtool turd

If the filesystem size rounded up to a multiple of the block size
is larger than what a user specified then round down to get something
that works but wastes a little space.

This happens reliably for me when building filesystems for CF parts
>1G; not sure why noone else is complaining.

Apply the big hammer:
o remove all of compat except for pwcache and strstuftoll; these might
end up in libutil or similar so keep them in the subdir
o mv getid.c up to the top level; this looks like something that'll be
makefs-specific
o eliminate private versions of .h files in sys; use system files instead
o eliminate private ffs_tables.c; use the system version directly (might
want to adopt const'ification at some point but that's the only diff I
can see)
o mv remaining code from sys to ffs and strip out unused bits; this now
becomes part of makefs
o add compat defs and shims to makefs.h
o strip all vestiges of nbtool_config.h, compat_defs.h, etc.
o fixup includes after file shuffling
o rename system #defines that do implicit byte swapping to have an _swap
suffix; e.g. DIRSIZ -> DIRSIZ_SWAP, cg_inosused -> cg_inosused_swap; if
we ever add endian-agnostic support to the kernel these can go back to
their original names
o strip some netbsd'isms that aren't worth shim'ing (e.g. _DIAGASSERT)

Code compiles w/o complaints but is untested.
