Implement -E option and <safearg.h> header.
The -E option is not passed through to the Awk implementation
any more, which is not particularly useful, because the option
resembles -f, and its argument requires likewise handling.
We achieve the semantics that -E <name> is equivalent to
-f <name> --.
From the GNU Awk user's perspective, this is a regression
in the semantics of -E which also has the effect of suppressing
the processing of arguments which look like variable assignments.
To make up for that, we provide the <safearg.h> header which
suppresses all implicit treatment of the remaining arguments.
