2914feeb7e mdoc: make pages render with mandoc
It's a bit more pedantic regarding .Bl list elements. This has an added
benefit of unbreaking the ipfw(8) manpage, where groff was silently
skipping one list element.

4e5867d27e This fixes the "getfile: lost data" panic when restoring dumps
on a 7.0 or later system that were created on a pre-5.0 system.
We must ensure that restore zeros out the previously undefined
birthtime and external attribute size fields when reading dump
tapes made by the UFS1 dump program.

The problem is that UFS2 dump carefully zeros out the unused
birthtime and external attribute size fields in the dump header
when dumping UFS1 filesystems, but the UFS1 dump didn't know about
those fields (they were spares) so just left whatever random junk
was in them. So, when restoring one of these pre-UFS2 dumps,
the new restore would eventually trip across a header that had
a non-zero external attribute size and try to extract it. That
consumed several tape blocks which left it totally out of sync
and very unhappy (i.e., the panic). The fix is in the gethead()
function which modernizes old headers by copying old fields to
their new location (and with this fix) zeroing out previously
undefined fields.

aed3576d26 restore(8) does not check for write failure while building two temp
files containing directory and ownership data. If /tmp fills, the
console is blasted with zillions of "file system full" errors, and
restore continues on, even though directory and/or ownership data
has been lost. This is particularly likely to happen when running
from the live CD, which has little /tmp space.

772ad651bf Update the dump program to save extended attributes. Update
the restore program to restore all dumped extended attributes.

If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.

The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.

This resolves PR 93085 which will be closed once the code
has been MFC'ed.

Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

cbc8bb98ef Add a "-D" flag to restore which puts it into "degraded" mode. This
makes restore less efficient, but it makes a bigger effore to read
corrupted dumps. Specifiacally, when in degreded mode:

	1) Restore shifts the input by 1 byte if it sees a problem,
	rather than one tape block.
	2) It doesn't assume the inodes are stored in ascending order.
	3) It turns some panics into warning printfs.

We also verify some fields more carefully than before.

There's probably more a degreded mode could do, but this seems to
help a lot.

66b4217151 Restore the ability to read FreeBSD 1 tapes (and I think any net2
based tapes, but I'm not sure where NFS_MAGIC was introduced after
4.3).  When support for the pre-4.4 format was removed (the ability to
read 4.2 and 4.3 BSD tapes), the old format inode conversion was
junked as well.  However, FreeBSD 1 dump tapes use the NFS_MAGIC
format, but have this inode format.  Before, restore would fail
complaining that '.' wasn't found and the root directory wasn't on
this tape.  Since the conversion from the not so old format is
relatively trivial, restore the code to make that conversion.

FreeBSD 1 dumps are once again readable.

84c248f850 c_tapea and c_firstrec are used for TS_TAPE blocks, so convert them
for the old (4.4-lite through FreeBSD 4.x and *BSD) format.  It looks
like they aren't used for TS_INODE, but conversion costs so little
there that I've not removed them there (in case my grep was wrong).

This makes at least some of the tapes work for me again.  Now, to
regresion test all my dusty tapes...
