location where we expect to find an ffsv2 superblock.
It could be the first alternate for a ffsv1 filesystem with 64k blocks.

which is silly. Luckily, it really does return the correct result if
interpreted as an unsigned int. This change lets dump work on 32-bit
systems that have more than 2GB of RAM.
64 bit block pointers, extended attribute storage, and a few
other things.
This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

Don't install "setgid tty", and remove now unnecessary gid/egid swapping.
Remove utmp trawling code pulled in from usr.bin/who.
The Code is now simpler, and more portable (without the utmp cruft) too.
This is derived from similar work in OpenBSD.
Files in subdirectories of directories that have the nodump flag set
are sometimes incorrectly being dumped.
The problem arises because the subdirectory only gets its entry
cleared from usedinomap if it is also present in dumpinomap, and it is
the absence of a directory in usedinomap that internally indicates
that the directory is under the effects of UF_NODUMP (either directly
or inherited).

to define the tape size. Requires the tape driver to either return ENOSPC
at end of media, or 0 when a write is attempted (such as the "early warning"
support in st(4) enabled with "mt eew 1"). From FreeBSD.
- Fix error if first tape was write protected. Fix NetBSD PRs 4754 and 6098.
- Make dump exit codes confirm to manual page.
- Use \a instead of \7 to make noise.
- Fix estimated number of tapes for huge dumps to cartridges.
- Use <sys/queue.h> SLIST_* instead of home-rolled lists.
- Do not exit if unable to read or create /etc/dumpdates.
- Support output (tape) device returning ENOSPC for end-of-media on a write.
Fixes by me:
- Remove unused ddates_in.
- Don't dump core if SIGINFO is received before 1 second has elapsed.
- Only process SIGINFO in current "active" child.
- Don't dump core in -w if dumpdates wasn't readable and ddatev == NULL
- Minor KNF; wrap some lines
past EOM and fail with "short read error". This check was part of
traverse.c::bread(), and was removed when that function was migrated
to rcache.c::rawread() as part of the "read cache" functionality.
This should fix the problem with dump barfing on "short read" when "-r 0",
but I'm still debugging the problem where dump gets to a point and
"does nothing" when the read cache is being used.
