Add iflag and oflag operands to dd(1)

Like GNU dd(1) similar operands, iflag and oflag allow specifying the
O_* flags given to open(2) for the input and the output file. The values
are comma-sepratated, lower-case, O_ prefix-stripped constants documented
in open(2).

Since iflag and oflag override default values, specifying oflag means
O_CREATE is not set by default and must be specified explicitely.

Some values do not make sense (e.g.: iflag=directory) but are still used
and will raise a warning. For oflag, values rdonly, rdwr and wronly are
filtered out with a warning (dd(1) attempts open(2) with O_RDWR and
then O_WRONLY on failure).

Specifying oflag=trunc along with (seek, oseek or conv=notrunc) is
contradictory and will raise an error.

iflag and oflag are disabled if building with -DMALLPROG
