617dbd3c84 Replace the use of %qd with intmax_t/%jd and fix a number of -Wall
and -Wformat warnings:
 o Include timeconv.h for the time conversion functions.
 o Remove unused variables.
 o Correct a few cases where %d was used when printing longs.

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).

170ac683f2 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.

keywords.

5b3817c60b 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.

8cc6e4d84a 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.
