1c85e6a35d 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).

280a49ec4b 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.)

8660ce229c 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.

ed873335b7 Respect style(9), one must not include both <sys/types.h> and
<sys/param.h> (the latter includes the former).

0227048a1f Correct use of .Nm. Use .Bl/.El for enumerating options. Use .An. Correct
formatting of rcsid. Remove unused #includes. Do not use memory after
freeing it.

76863c5104 Make this compile. Mostly use the new names for the ctime/atime/mtime
stamps in the inodes and call one of fsck's utility funcs with a new arg.
