Restore backward compatibility of UFS2 with previous NetBSD releases by
disabling support in UFS2 for extended attributes (including ACLs).
Add a new variant of UFS2 called "UFS2ea" that does support extended attributes.
Add new	fsck_ffs operations "-c	ea" and	"-c no-ea" to convert file systems
from UFS2 to UFS2ea and	vice-versa (both of which delete all existing extended
attributes in the process).

Rebase to HEAD as of a few days ago.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

fix unused variable warnings.

resync from head

fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB()
dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB()

(Christos already did the lfs ones a few days back)

Rename ambiguous macros:
   MAXDIRSIZE -> UFS_MAXDIRSIZE or LFS_MAXDIRSIZE
   NINDIR -> FFS_NINDIR, EXT2_NINDIR, LFS_NINDIR, or MFS_NINDIR
   INOPB -> FFS_INOPB, LFS_INOPB
   INOPF -> FFS_INOPF, LFS_INOPF
   blksize -> ffs_blksize, ext2_blksize, or lfs_blksize
   sblksize -> ffs_blksize

These are not the only ambiguously defined filesystem macros, of
course, there's a pile more. I may not have found all the ambiguous
definitions of blksize(), too, as there are a lot of other things
called 'blksize' in the system.

Remove clause 3 and 4 from TNF licenses

include <signal.h> where signal(3) is used

appease gcc -Wuninitialized

Remove main() prototype; WARNS=3

Don't use 1st alternate superblock at offset 64k for ffsv1.
Fixes part of PR kern/24809

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

use arc4random

clear errno before strto(u)l() if we're going to test it for ERANGE afterwards

Add support for UFS2. UFS2 is an enhanced FFS, adding support for
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.

need ufs/ufs/dinode.h for ufs/ffs/fs.h

Pull up revision 1.14 (requested by lukem):
  Call ffs_sb_swap() with the correct arguments.  Fixes problems
  with using other-endian file systems.

this doesn't need <ufs/ufs/inode.h>

change -F semantics to treat the argument as a file system image; open it
`as-is' without attempting to determine the device name with opendisk(3),
and don't attempt to read a disklabel.

remove #include <ufs/ufs/quota.h> where it was just to appease
<ufs/ufs/inode.h>, since the latter now includes the former.  leave the former
in source that obviously uses specific bits of it (for completeness.)

- add -F - manipulate a file system image in a regular file (instead of
  a special device).
- implement statistics printing on SIGINFO

remove third argument (`int ns') from ffs_sb_swap(), and let ffs_sb_swap()
determine the endianness of the `struct fs *o' superblock from o->fs_magic
and set needswap as necessary, rather than trusting the caller to get
it right.  invariably, almost every caller of ffs_sb_swap() was calling it
with ns set to the wrong value for ns anyway!
ansi KNF ffs_bswap.c declarations whilst here.

this fixes all sorts of problems when trying to use other-endian file systems,
notably the kernel trying to access memory *way* off, possibly corrupting or
panicing, and userland programs SEGVing and/or corrupting things (e.g,
"fsck_ffs -B"  to swap a file system endianness).

whilst the previous rev of ffs_bswap.c (1.10, 2000/12/23) made this problem
worse, i suspect that the problem was always there and previous versions
just happened not to trash things at the wrong time.

FFS_EI should now be a lot more stable.

ansi knf, WARNS=2

convert to use getprogname()

fix nested extern. While I am here assign copyright to TNF.

Use DINODE_SIZE instead of sizeof(struct dinode) and/or pointer arithmetic.

from Erik Bertelsen <erik@mediator.uni-c.dk>
 { put } { in } { lots } { of } { these } { to } { shut } { up } { egcs }

Add support for non-native byteorder FFS.

Work around ggc-2.7.2 off_t initialization bug on m68k.

* cleanup for WARNS=1
* prefix hex numbers with '0x'

Fix type error that caused offset to wrap at 4GB.

* add `-x' option to usage().
* `=' vs. `==' in a comparison.

string.h for protos

Fix NetBSD RCS ID tag

First pass at fsirand. Needs /dev/random to do things right.
