MFC r326276:

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

MFC r316055: makefs: sort roundup with the other off_t members in fsinfo_t

Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

makefs: Provide a -T option to set timestamps to a consistent value

This is taken from the NetBSD versions listed below and adapted to the
makefs version in FreeBSD, along with a bug fix from cem@ that will be
sent to NetBSD.

makefs: introduce a new option to specify what to round the resulting
image up to.

From ticket:

While trying to run FreeBSD/mips on some device having very small flash media,
one is forced to compress file system with mkulzma(8) utility. It is desirable
to specify small UFS block/fragment sizes like 4096/512 bytes for makefs(8)
and big compression block size like 65535 bytes to mkulzma at the same time.
Then one obtains very good comression ratios (like 75% and more) but faces
the following problem.

geom_uncompress kernel module reports GEOM provider size rounded up to its
compression block size. Generally, this changes original media size and now
it fails to match the size of embedded UFS file system that leads to other
problems, f.e. geom_label kernel module does not like this and skips the
file system while tasting the GEOM and looking for UFS label.

This makes it impossible to refer to the file system using known UFS label
instead of something like /dev/map/rootfs.uncompress.

The following patch introduces new command line option "-r roundup" for makefs
that makes it round up the image to specified block size. Hence, geom_uncompress
does not change GEOM media size for images rounded that way and geom_label
accepts such GEOMs just fine.

With the patch applied, one can use following commands:

$ makefs -t ffs -r 65536 -o bsize=4096,fsize=512,label=flash optimization=space fs.img fs
$ mkulzma -s 65536 -o fs.img.ulzma fs.img

Remove duplicated copies of various NetBSD compatibility shims used by
makefs and use libnetbsd, contrib/mtree, and contrib/mknod instead.

Allow contents of multiple directories to be merged to the current image.
Note this patch was submitted to NetBSD and they already adopted it.

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.

import netbsd makefs tool

add properties and FreeBSD id's

fix stuff i broke

unbreak cg_chkmagic_swap

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.
