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).

3d438ad61f 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?)

d030d2d2ae Many places in the code NULL is used in integer context, where
plain 0 should be used.  This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

d87d79aefe Merge from Lite2
- cleanups,
 - whiteout support
 - bug fixes (chflags missing on a few file types etc)
The dump/restore folks would want to have a closer look at this, the
change is pretty big.

eaa86f9d7f Don't use __dead or __pure in user code. They were obfuscations
for gcc >= 2.5 and no-ops for gcc >= 2.6.  Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

4d14a29026 Check a pointer in skipdirs() before dereferencing it. I don't fully
understand why it can become a null pointer under some circumstances,
but i've got a pile of tapes where this happens, and running it thru a
debugger proved that simply ending the loop in this case did the right
thing.

Anyway, it cannot make it worse than now, where restore kills itself
with "Memory fault".
