Add external attribute dumping and restoring support from FreeBSD.
Does not fully work yet, attributes are being saved and restored correctly,
but don't appear in the restored files somehow.

Document what rdump is (was once) for. PR 53442.

Use getfsspecname() to fill the filesystem argument in dumpdates.
While here, make sure that the error strings terminate with newline
consistently, and add a function that adds the system error string.

Add -U flag to dump(8) and dump_lfs(8) to specify dumpdates entry
This address situations where dump(8) cannot figure out the device being
dumped. It also allows tracking of subvolume dumps by using virtual
device as dumpdates entry.

Bump date for previous.

- mark Exit() __dead

- update NAME_MAX to match the kernel.
- add a comment about where the constant is used.

Hack up dinode usage to be 64 vs. 32 as needed. Part 1.

(This part changes the native lfs code; the ufs-derived code already
has 64 vs. 32 logic, but as aspects of it are unsafe, and don't
entirely interoperate cleanly with the lfs 64/32 stuff, pass 2 will be
rehashing that.)

Add a new lfs header file: lfs_accessors.h.

This contains all the accessor functions and macros out of lfs.h.
Add an include of lfs_accessors.h after all uses of lfs.h... except
for code that wants to define its own struct lfs-alike that the
accessors are supposed to play along with. For these, set STRUCT_LFS
and include lfs_accessors.h after the necessary structure has been
defined, so that lfs_accessors.h can emit functions in terms of it.

Stuff UFS_ in front of a few of ufs's symbols to reduce namespace
pollution. Specifically:
   ROOTINO -> UFS_ROOTINO
   WINO -> UFS_WINO
   NXADDR -> UFS_NXADDR
   NDADDR -> UFS_NDADDR
   NIADDR -> UFS_NIADDR
   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.

Use __printflike.

Change LFCNWRAP{STOP,GO} to make them more suitable for snapshotting; in
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again.  Updated the ckckp
regression test to use the new semantics.

dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4).  Fixed a couple
other problems with dump_lfs that manifested themselves during testing.

Don't use cast expressions as lvalues as newer versions of gcc warn.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

sprinkle const

Replace the statfs() family of system calls with statvfs().
Retain binary compatibility.

Adjust tstart_volume (volume start time) by the time spent in query(),
similar to the adjustment for tstart_writing made in optr.c rev 1.4.
Should fix PR bin/19711 from matthew green.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22308, verified by myself.

Add support for UFS2. UFS2 is an enhanced FFS, adding support for
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.

Originally written by Kirk McKusick and Network Associates Laboratories for
FreeBSD.

Use "wall -g operator" (instead of private code) to broadcast() messages to
members of the operator group.
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.

Bump daddr_t to 64 bits. Replace it with int32_t in all places where
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.

Pull up revision 1.27 (via patch, requested by bouyer):
  Improve behaviour when a path is given:
   1) check if the path is an unmounted file system listed in fstab
   2) check if it is a path to a mounted file system not listed in fstab
  Fixes PR#15790.

Pull up revision 1.23 (via patch, requested by bouyer):
  Fix the ``Implement -l <timeout>'' pull-up;
  restore needs the rcmd operation.

Pull up revision 1.33 (via patch, requested by bouyer):
  Add an ``-a'' option to ``auto-size'' the tape, rather than
  relying upon other options to define the tape size.

Pull up revisions 1.31-1.32 (via patch, requested by bouyer):
  Various fixes:
   o Fix error if first tape is write-protected; fixes PR#4754 and PR#6098
   o Make error codes conform to manual page
   o Use \a to make noise
   o Fix estimated number of tapes for huge dumps to cartridges
   o Use <sys/queue.h> SLIST_* macros instead of homegrown variants
   o Do not exit if unable to read/create /etc/dumpdates
   o Support output (tape) device returning ENOSPC for end-of-media on write
   o Don't dump core if SIGINFO is received before 1 second has elapsed
   o Only process SIGINFO in currently active child
   o Ensure current (sub)block isn't past end of file system -- fixes
     "spins forever but does nothing" bug.
   o Some other minor fixes (types, whitespace, KNF, unifdef sunos, ...)

Pull up revision 1.30 (via patch, requested by bouyer):
  Implement ``-l <timeout>'' option for use with e.g. autochangers.

Add -a to "auto-size" the tape, rather than relying upon other options
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.

Fixes 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

- use correct type for minTime in findlru()  (size_t instead of int)
- clean up whitespace

Add a -l (autoload) flag. For multivolume dumps, this makes dump eject the
tape when a volume is full, and try to reopen the tape drive for 2 mn.
To be used with tape changers which load the next tape when the current one is
ejected.
While I'm there fix eject handling for remote tape.

Add the capability for dump to print timestamps on all informational
messages.

s/filesystem/file system/

* improve parsing of file-systems-to-dump when a path is given:
      - if it's a path to an unmounted file-system listed in /etc/fstab, use
	that instead of assuming the user wanted a subtree dump of the parent
	directory. this restores the behaviour of dump before the subtree
	dumping code went in.
      - if it's a path to a mounted file-system which is not in /etc/fstab,
	use the info from getmntinfo(3). previously, dump would choke.
* implement error checked malloc(), calloc(), strdup(), and use
  appropriately (some of the calloc()s weren't being checked)
* use 'file-system' instead of 'filesystem' in the man page

Working version of aborted dump{,_lfs} join.

Back out changes made on the 29th, not at all the changes I intended to commit.
(I don't know how I did it though ... I'll figure it out tonight.)
I'll reapply this, in a working form, this evening.

Adapt dump(8) to use filestore-independent (but still ufs-specific)
replacements for NINDIR, fsbtodb, etc.  Create dump_lfs by adding a few
LFS-filestore-specific routines.  As described in PR#8317.

Implement a read cache, as announced on tech-userlevel. Default is 32k
read buffer size, 512 buffer or 15% of the user memory. Can be changed
with the -k and -s options.

#include machine/bswap.h and remove -lutil.

Add support for non-native byte order FFS. The dump is in filesystem byte
order, restore already knows how to byteswap dumps.

remove __dead

* Add the ability to dump specific files & directories of a single
  filesystem. This uses fts(3) to access the directory structure (and
  not the raw device), so the standard access permissions are adhered
  to (unlike dumping an entire filesystem, which just requires read
  access to the raw disk device).
* Support SIGINFO status reporting.
* Remove now unused variables that previously stored the (e)uid.
* Be more informative in a couple of error messages.

Implement changes from [bin/1915]
* 'w' and 'W' display the year
* verbosity additions displaying total & per-volume transfer times and rates
