_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

<ufs/ufs/inode.h>, since the latter has a lot of cruft we don't need
and it #include's way more stuff in <sys/*> (etc) than is needed here.
yet another nail in the "let's make makefs a proper host tool" coffin.
- #include <ufs/[uf]fs/*.h> instead of "ufs/[uf]fs/*.h", and don't bother
with -I../../sys; we'll solve the hostprog problem another way and
unconditionally pulling in NetBSD-current's usr/src/sys on a host system
could be a Bad Thing.
- when calculating file size, round up to frag size not block size
- #define FFS_EI in makefs.h, and include that before [uf]fs/*.h
other stuff:
- round up final size to next block (instead of next sector)
- protect makefs.h from multiple inclusion
It doesn't need any special privileges or kernel devices.
Only ffs image creation is supported at this time, although makefs has been
designed to allow the addition of other file system formats by writing new
back-ends.
