ufs: fixed signed/unsigned bugs affecting large file systems

Apply these commits from FreeBSD:
  commit e870d1e6f97cc73308c11c40684b775bcfa906a2
  Author: Kirk McKusick <mckusick@FreeBSD.org>
  Date:   Wed Feb 10 20:10:35 2010 +0000
    This fix corrects a problem in the file system that treats large
    inode numbers as negative rather than unsigned. For a default
    (16K block) file system, this bug began to show up at a file system
    size above about 16Tb.
    To fully handle this problem, newfs must be updated to ensure that
    it will never create a filesystem with more than 2^32 inodes. That
    patch will be forthcoming soon.

    One last pass to get all the unsigned comparisons correct.


In additional to the changes from FreeBSD, this commit includes quite a few
related changes to appease -Wsign-compare.

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).

improve error messages (remove \n, use __func__, etc)

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")

Stick ffs_, ext2_, chfs_, filecore_, cd9660_, or mfs_ in front of
the following symbols so as to disambiguate fully. (Christos already
did the lfs ones.)

   lblkno
   lblktosize
   lfragtosize
   numfrags
   blkroundup
   fragroundup

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

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

resync with head

sync with head

Stuff UFS_ in front of a few of ufs's symbols to reduce namespace
pollution. Specifically:
   ROOTINO -> UFS_ROOTINO
   WINO -> UFS_WINO
   NXADDR -> UFS_NXADDR
   NDADDR -> UFS_NDADDR
   NIADDR -> UFS_NIADDR
   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.

sync with head

use getfsspecname()

more code deduplication

more KNF

use merged out code.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

Make it build in new world.
Don't attempt to update in-kernel quota, but instead warn if quotas
are already on. The rc.d script runs quotacheck before quotaon
so this shouldn't be a problem.

64 bit inode changes

PR/23971: Greg A. Woods: Fix quotacheck infinite loop with uid == UINT32_MAX.
While I am there, pass WARNS=3

fffv2 might not have FS_FLAGS_UPDATED set

When searching for the superblock, don't pick an ffsv1 superblock from the
location where we expect to find an ffsv2 superblock.
It could be the first alternate for a ffsv1 filesystem with 64k blocks.
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.

Add -l to usage.

don't allow -l without -a

Add -q to usage.

PR/23971: Robert Elz: Quotacheck fails when max uid is present and takes
forever if there are large gaps in the uid space. It also does not work
properly with the fsck preen code it uses.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22366, verified by myself.

use bounded string op

Skip over inodes <= ROOTINO for getnextinode(). PR 21208 by Geoff Wing.

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.

Pull up versions 1.22-1.23 (requested by bouyer in ticket #1070)
 Add SIGINFO support.

Bump daddr_t to 64 bits. Replace it with int32_t in all places where
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.

Add SIGINFO support.

Pull up revision 1.22 (requested by lukem):
  Call ffs_sb_swap() with the correct arguments.  Fixes problems
  with using other-endian file systems.

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.

convert to use getprogname()

If -a, we do not want to pay the cost of processing every group and password
entry if there are no filesystems with quotas. Speeds up boot on a large YP
site without quotas considerably. If a filesystem has quotas we process
/etc/fstab twice, which is very cheap in relative terms.

{} fixes from Erik Bertelsen <erik@erik-be.uni-c.dk> (PR 6047) to shut up egcs.

const poisoning.

Add support for non-native byteorder FFS.
The quota file is still in host byteorder. quotacheck needs to be re-run
when a FS has been moved to an architecture to another. Running quota
on a non-native byteorder ffs is considered a marginal case.

Fix uninitialized variable

* resolve conflicts from lite-2 merge
* cleanup for WARNS=1

imported from lite-2

Update for newer preen interface.

This broke when preen.c moved from fsck_ffs to fsck. Update and cleanup.

Use an integer instead of a char for the getopt() return value in order
to work with compilers that use unsigned chars.
Compare the getopt() return value with -1 instead of EOF.

Fix an obvious bogon when checking multiple file systems, and use the libc
