b7d86f5e4c In "dd progress=N", let the value of N control how often 
to print a "." to stderr.  Previously, any non-zero
value behaved like "progress=1".

6b4933739d add support for conv=sparse 
inspired by freebsd, although this patch attempts
to avoid some potential bugs in their implementation.

39973c5237 Optimise previous change, using fcntl(F_DUPFD) to locate a free descriptor 
for us, rather than iterating until satisfied.

Suggested by David Laight.

0b16f71074 Avoid corrupting the dd(1) IO streams. This would happen by accidentally 
outputting to the files being manipulated by opening a file in the standard IO
descriptor space.  In particular, an output file unlucky enough to be sitting
on descriptor 2 (stderr) is certain to be corrupted.

Addresses PR bin/8521, and passes the recently committed regression test
"bin/dd".

458ed23412 As discusses a little while back on tech-userlevel: 
If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.

While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.

301fb81a16 Replace {u_,}longlong_t usage with {u,}int64_t, as the former has 
"issues" and really shouldn't be used outside of the Sun XDR stuff.
Thanks again to Chuck Silvers for reminding me.

b6ce735c04 - Use u_longlong_t instead of u_quad_t, u_long, or int for various buffer sizes 
- Add strsuftoull(), which parses a number into a u_longlong_t, with
  multiplication support, and support for 'g' (GB) and 't' (TB) suffices.
  If an error occurs, print to stderr and exit.
  Based on get_blk() from args.c and strsufto*() (in other programs)
- Add strsuftoullx(), which acts as per strsuftoull() but returns the
  error in the supplied buffer instead (if the returned buffer != "", an
  error occurred)
- Replace get_bsz() use with strsuftoull()
- Remove (now) unnecessary argument validation
- Remove unused {f,p,s,t}_stats fields in struct IO
