The current /etc/dumpdates file restricts device names to 32 characters.
With the addition of various GEOM layers some device names now exceed
this length, for example /dev/mirror/encrypted.elig.journal. This
change expands the field to 53 bytes which brings the /etc/dumpdates
lines to 80 characters. Exceeding 80 characters makes the /etc/dumpdates
file much less human readable. A test is added to dump so that it
verifies that the device name will fit in the 53 character field
failing the dump if it is too long.

This change has been checked to verify that its /etc/dumpdates file
is compatible with older versions of dump.

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.

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).

I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions. e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard. They will eventually be replaced when a real standard
comes out of committee.

Zap a number of #ifdef sunos blocks, and all of the `register'
keywords.

Make the protocol/dumprestore.h header match restore's idea of the dump
header for the case where sizeof(time_t) != sizeof(int). dumprestore.h
was embedding time_t when it should have been embedding int32_t.

Use time_to_time32() and time32_to_time() to convert between the
protocoll/file-format time and time_t.

Remove two lint directives that aren't needed since rev 1.5.

Make rev 1.5 better match the rest of dump(8)'s output.

Do not exit if unable to read /etc/dumpdates or create it.
If one is trying to dump or repair an ill system, give the user a fighting
chance. Refusing to operate w/o a very non-critical file (feature) is
just plain stupid.

Use <sys/queue.h> instead of home-rolled list.
