Instead of extending fsinfo_t it now holds a void * to file system specific
data. This is then setup/cleaned up by the additional of 2 additional
callbacks. Makes adding new filesystems simpler as almost no code has
to be updated in the generic makefs code now.
_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).

XXX The real problem is that some sources include {.CURDIR}/ffs/ffs_extern.h

64 bit block pointers, extended attribute storage, and a few
other things.
This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.
Originally written by Kirk McKusick and Network Associates Laboratories for
FreeBSD.
round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
mkfs() do its job
- pass cpgflg=1 to mkfs() if the user provided cpg, =0 otherwise
- improve error reporting in ffs_write_file()
- only add superblock & block map slop for one cylinder group.
trying to calculate the number of required cylinder groups caused
too many problems when tweaking parameters for small file systems.
rely upon slop from minfree, and upon ffs_write_file() to complain
if the user is too aggressive about tweaking the parameters
* revision 1.56
the change of calculation of inodes per group in rev 1.52 was far too
aggressive; rework to be a bit less susceptable to round-off error.
now it's likely that the density might not be obtained with a small
filesystem with a large number of inodes (e.g -s 4M -i 1k), but that's
an extremely unlikely corner case that can easily be rectified with
command-line arguments.

[ this fixes a problem in makefs(8) that matt green reported ]
* revision 1.58
clamp bsize to MAXBSIZE
* revision 1.59
don't bother printing a warning about the cylinder group size being
restricted if -c isn't given; it just confuses a user of newfs (and
the cpg info is printed as part of the display anyway), and prints an
unnecessary warning for mount_mfs.
XXX: I must rework newfs/mkfs.c to make it easier to just .PATH into makefs(8)
<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.
This program was designed & implemented by Luke Mewburn of Wasabi Systems.
