Fix usr.bin/ and usr.sbin/ build with a 64-bit ino_t.

Original code by: Gleb Kurtsou

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.

Make `quot -a' work when we've got slashes in the device name.

A very long time ago we had raw device nodes. quot(8) was supposed to
use these when running `quot -a'. For some reason the code got once
changed to strip the device name until it reaches the last slash. This
is not reliable, because this means /dev/mirror/foo will be stripped to
/dev/foo.

This bug also exists on RELENG_7 and RELENG_6, but I think I'll just
merge them back somewhere after the upcoming releases. There's no rush.

The quot command expected all inodes contents to be valid, however
on UFS2 inodes are initialised as they are needed, rather than at
newfs time. When quot encountered these inodes it could produce
crazy results.

Now, on UFS2 filesystems, quot's get_inode function will bzero
unallicated inodes before passing them back to a caller. This is
how UFS2 initialises new inodes, so this should work OK.

Also, while I'm here, make quot exit with an error if it finds
inodes of an unknown type. This should help catch future problems
of this type.

Remove unused variables.

Use __FBSDID over rcsid[]. Protect copyright[] where needed.

Repair the UFS2 superblock location consistency check so that it succeeds
on valid superblocks instead of issuing the error "not a BSD filesystem".
fs_sblockloc is a byte offset, not a fragment number. This change makes
quot work properly on UFS2 filesystems, which is important now that UFS2
is the default.

Back out rev 1.19; getbsize(3)'s original interface has been restored.

another int * to size_t * change for getbsize() to make it compile

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).

For quot, just back out revs. 1.1 and 1.2 and change MNT_FFS to
