rillig | dd: clean up function summary
No functional change. Ideally the binary would have stayed the same, but
GCC 10.3.0 inserts a nop and reorders the code.

rillig | dd: fix lint error about 'return expr' from void function
No change to the resulting binary. The 'return' statements are necessary
for GCC to generate the exact same object code, even though they can be
removed without affecting the functionality, as seen before the 'else'.

rillig | bin: remove unnecessary lint comment CONSTCOND
Since 2021-01-31, lint no longer warns about 'do ... while (0)'.
No functional change.

jym | branches: 1.23.42;
As suggested by Enami, rework the msgfmt logic a bit:
- error out when an unknown specifier is used. Do this in f_msgfmt(),
before dd(1) starts operation.
- allow buffer_write() to flush the internal buffer even when NULL is
passed as parameter.
Some whitespace fixes too.

jym | Add a new command to dd(1): msgfmt. The command modifies the
output of the information summary returned by dd(1). This can be used
to specify messages in a more usable (or parseable) format like
human-readable values.
My intent is to re-use this for building image files and quick I/O
benchmarking.

Convert to using raise_default_signal(3).

lukem | branches: 1.20.4;
In the SIGINT handler, explicitly display a summary and then raise the
default SIGINT handler to exit, rather than exit(0) and relying upon the
atexit() to display the summary.
Per SUS6.

dbj | add support for conv=sparse

to avoid some potential bugs in their implementation.

jschauma | 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.

enami | a bit more cosmetic changes.
|
| 1.13 |
| 25-Nov-2001 |
lukem | - 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

ross | In the words of Our Fearless Leader, I am "utterly sick" of dd(1)
lying to me about transfer rates. Do some fixed point frobbing to get
stuff like: 2486864 bytes transferred in 0.272 secs (9142882 bytes/sec)
