MFC r254397:
Mark the makefs(8) '-p' flag as deprecated in preference for
the '-Z' flag for compatibility with NetBSD.

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

Allow contents of multiple directories to be merged to the current image.

MFC r226482

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.
