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.

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.

Remove the rif/rof options and add rump.dd. This makes usage
...
consistent with other rump clients. Copying between kernels is
done using the host pipe, e.g.:
dd if=foo rof=bar skip=1 seek=1 => dd if=foo skip=1 | rump.dd of=bar seek=1
Also, the pipe idiom extends to copying between different rump
kernels, e.g.:
env RUMP_SERVER=unix://srv1 rump.dd if=thefile \
| env RUMP_SERVER=unix://srv2 rump.dd of=thefile
Pipe approach suggested by yamt (thanks!)

Add two new operands: "rif" and "rof". They operate exactly like
...
"if" and "of" with the exception that the communicate with a rump
kernel instead of the host kernel.
For example, to write stdout to /tmp/file.txt in a rump kernel namespace:
dd rof=/tmp/file.txt
copy /file1 to /file2 inside a rump kernel:
dd rif=/file1 rof=/file2
copy a snippet from /dev/rmd0d on the rump kernel to the host fs:
dd rif=/dev/rmd0d of=save seek=1000 count=3
Eat that, usermode OS.
(I'll document the operands one I have some manpage to refer to
for rump client use).
