r266930 (by jmg):

convert to using the _daddr_t types like newfs was...

Put the superblock in the correct possition for UFS2... There is a bug
in FFS that if we don't put it here (for UFS2), it will forcefully
relocate the superblock, and I believe cause data loss..

I have a fix for that, but w/ how many releases are broken, we won't be
able to switch to the better _FLOPPY (block 0) for this for a while..

r289225 (by sbruno):

makefs(8) leaves sblock.fs_providersize uninitialized (zero) that can be easily
checked with dumpfs(8). This may lead to other problems, f.e. geom_label kernel
module sanity checks do not like zero fs_old_size value and skips such UFS1
file system while tasting (fs_old_size derives from sblock.fs_providersize).

Ensure that makefs.h is included when using ufs_bswap.h so the FFS_EI macro
is picked up when defined. Previously, ffs_subr.c was always built without
support for opposite endianess as it doesn't include makefs.h on its own.

Spelling fixes for usr.sbin/

Small cleanups to panic() prototype.

- Let panic() use _Noreturn and __printflike() instead of GCC-specific
attributes.
- Remove prototype from ffs_subr.c and let it include ffs_extern.h.
- Forward declare struct inode to make ffs_extern.h not depend on it.

Add support to makefs(8) to add UFS labels to images.

Drop the include of <ufs/ffs/ffs_extern.h> from usr.sbin/makefs/ffs/ffs_bswap.c
and usr.sbin/makefs/ffs/ffs_subr.c as they have no need of anything in that
file. No other programs or libraries include <ufs/ffs/ffs_extern.h> (nor
should they as it is totally in-kernel interfaces). For added protection
I enclosed the entire contents of <ufs/ffs/ffs_extern.h> in ifdef _KERNEL.

Feedback from: Bruce Evans and Tai-hwa Liang

Use alternative, less messy solution to avoid breakage after r223020:
put the snapdata structure between #ifdef _KERNEL guards.

Suggested by: kib

Apparently makefs needs a few more system headers to compile during
buildworld.

Unbreak usr.sbin/makefs after r223020.

import netbsd makefs tool

add properties and FreeBSD id's

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.
