The dump, fsck_ffs, fsdb, fsirand, newfs, makefs, and quot utilities
include sys/time.h instead of time.h. This include is incorrect as
per the manpages for the APIs and the POSIX definitions. This commit
replaces sys/time.h where necessary with time.h.

The commit also includes some minor style(9) header fixup in newfs.

This commit is part of a larger effort by Garrett Cooper started in
//depot/user/gcooper/posix-conformance-work/ -- to make FreeBSD more
POSIX compliant.

s/filesystem/file system/g as discussed on -developers

This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

Remove 'register' keyword.
It does not help modern compilers, and some may take some hit from it.
(I also found several functions that listed *every* of its 10 local vars with
"register" -- just how many free registers do people think machines have?)

Something i always wanted to see: add a function to print the list of
blocks allocated by some inode. Indirect blocks are printed
recursively, so beware :), the list could become lengthy...
(We should probably add some output pager to fsdb.)

Avoid pointless initialization of global variables to 0. This only
bloats the resulting binary file by forcing them out of .bss into
.data, while the C standard already guarantees them to become
initialized to 0 at program startup.

Allow fsdb the ability to work with entries named with whitespace embedded.

This works by retokenizing a line with a split limit so that if the
argument count for a command is greater than the number of arguments
formed by splitting apart the line of user input, the last argument
is instead all of the remainder of the input line.

Yes, I needed this capability at one point to fix a filesystem manually,
which happened to break with a problematic space-containing directory
entry.

Check that the mode argument to fsdb's `chmod' command contains no
inode type bits set. Previously it would let you set IFMT bits (but
not clear them). The `chtype' command should be be used instead
for changing the inode type; having chmod half-work only causes
confusion.

Adjust to the libedit enhancements some functions now take more parameters.

In fsdb, call sblock_init() which is now necessary to initialise
the global variable dev_bsize. Add a prototype for sblock_init()
to fsck.h, and set the return type correctly.

Remove unused includes.

$Id$ -> $FreeBSD$

More egcs warning fixes:
o main returns int not void
o use braces to avoid potentially ambiguous else

Note: The fix to natd is potentially functional in nature since I used
the indentation as the right thing rather than the struct semantics.
Someone more familiar with the code should double check me on this one.

Add chlen command so you can set the size of an inode. This was handy
