e3edab4a91 Add a "fillchar" command line argument to dd(1) that permits the user
to specify an alternative padding character when using a conversion
mode, or when using noerror with sync and an input error occurs.  This
facilities reading old and error-prone media by allowing the user to
more effectively mark error blocks in the output stream.

d3e240cb45 Change the behaviour of `-v' so that, e.g., stepping a month back
on March 31 won't take you to March 2 or 3 (now the result will
be the last day of February.)

In general, now stepping by months from the last days of the current
month A will take you to the very last day of the target month B if
B is shorter than A.

The previous version would just step to March 31 and rely on mktime(3)
to correct the date.  Despite its simplicity, such way was counter-intuitive
to users and caused pain to shell script writers.

d37df47d31 Join the 21st century: Cryptography is no longer an optional component
of releases.  The -DNOCRYPT build option still exists for anyone who
really wants to build non-cryptographic binaries, but the "crypto"
release distribution is now part of "base", and anyone installing from a
release will get cryptographic binaries.

239c9e601a Currently if a mount point is not accessible by the calling user,
invalid information will be printed if the -t flag is specified.

$ df -t ufs
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/ad0s1a    495726   139944   316124    31%    /
/dev/ad0s1e    253678     6438   226946     3%    /tmp
/dev/ad0s1f  56206340 13594248 38115586    26%    /usr
/dev/ad0s1d    694126    19812   618784     3%    /var
/dev/ad0s1d    694126    19812   618784     3%    /var
$

Note that the mount point which is not accessible shows
up as the previous file system that was printed. The reason
for this is that df -t will call statfs(2) on the pathname
supplied by getfsstat(2).

This is done to refresh the file system statistics in the
event that a previous file system had a long delay in
providing its stats.

This change affects the df utility in the following ways:
o Teach df has to deal with statfs(2) failing. If statfs(2)
  fails, fall back on the possibly stale stats provided by
  the initial call to getfsstat(2).
o Print a warning that the fs stats could possibly be stale
o Modify the man page and document this new behavior
  as a bug.

ce1affa2ac From SUSv3:
Any [standard output] field need not be meaningful in all

4bac4483db Have the main() routine calculate %CPU and (if needed) memory information
when copying per-process info before starting to sort the list.  This way,
sort-by-CPU or sort-by-memory will only calculate values once-per-process,
instead of twice-per-comparison.  Also take advantage of this to simplify

70bad4f75b If we are asked to print the total number of blocks, do so even if we
have no entries to print (either due to an empty directory or an
error).  This makes the -l and -s options more consistent, like
Solaris and (Debian) Linux.  To make this happen, tweak two
optimizations on the second call to display():

- Don't skip display() altogether, even if list == NULL.
- Don't skip the call to the printfn in display() if we
  need to print the total.
