The bufinit() call in fsck_ffs was moved in commit f190f9193b
from a function that is shared with fsdb to one that is private to fsck_ffs,
so add a bufinit() call in fsdb to compensate for that.

Only print buffer cache debug message when a cache lookup has been done.
When running `fsck_ffs -d` on a gjournal'ed filesystem, it's possible
that totalreads is greater than zero when no cache lookup has been
done - causing a divide by zero. This commit fixes the following error:
Floating point exception (core dumped)

The segfault was being hit in ckfini() (sbin/fsck_ffs/fsutil.c)
while attempting to traverse the buffer cache to flush dirty buffers.
The tail queue used for the buffer cache was not initialized before
dropping into gjournal_check(). Move the buffer initialization earlier
so that it has been done before calling gjournal_check().

The following config could crash pfctl:
altq on igb0 fairq bandwidth 1Gb queue { qLink }
queue qLink fairq(default)
That happens because when we're parsing the parent queue (on igb0) it
doesn't have a parent, and the check in eval_pfqueue_fairq() checks
pa->parent rather than parent.
This was changed in eval_pfqueue_hfsc() in
1d34c9dac8, but not for fairq.

Pass 1b of fsck_ffs runs only when Pass 1 has found duplicate blocks.
Pass 1 only knows that a block is duplicate when it finds the second

On Linux, there's a similar set of programs to ours, but that end in the
letters 'sum'. These act basically like FreeBSD versions run with the -r
option. Add code so that when the program ends in 'sum' you get the
linux -r behavior. This is enough to make most things that use sha*sum
work correctly (the -c / --check options, as well as the long args are
not implemented). When running with the -sum programs, ignore -t instead
of running internal speed tests and make -c an error.

Add asserts to prevent overflows of c_addr.
It is clearly wrong as the statement immediately above it in the
code which is deciding if the data will fit is:
if (spcl.c_count + blks > TP_NINDIR)
return (0);
As is pointed out in the bug report, the assert should be:
(spcl.c_count + blks <= TP_NINDIR)
This commit corrects the assert. I am sorry that it took so long to

UFS does not allow files to end with a hole; it requires that the
last block of a file be allocated. As fsck_ffs(8) initially scans
each allocated inode, it tracks the last allocated block in the
inode. It then checks that the inode's size falls in the last
allocated block. If the last allocated block falls before the size,
a `file size beyond end of allocated file' warning is issued and
the file is shortened to reference the last allocated block (to avoid
having it reference a hole at its end). If the last allocated block
falls after the size, a `partially truncated file' warning is issued
and all blocks following the block referenced by the size are freed.
Because of an incorrect unsigned comparison, this test was failing
to handle files with no allocated blocks but non-zero size (which
should have had their size reset to zero). Once that was fixed the
test started incorrectly complaining about short symbolic links
that place the link path in the inode rather than in a disk block.
Because these symbolic links have a non-zero size, but no allocated
blocks, fsck_ffs wanted to zero out their size. This patch has to
detect and avoid changing the size of such symbolic links.

Back in the day, we used to have a number of entries that were either

etc. Back then, we tried to line up the 'secure' columns by using the
construct 'on secure' or 'off secure' (one space or two). Now that these
have all moved to a conditional construct, remove the second space on
the ttys that still have it. This reduces diffs between the different
ttys and is no functional change. i386 and amd64 did this a long time
ago, and those are the only ones that affected external users (who used
to sed 's/on /off /' the entires as part of the automation).
