Don't rely on $0 to determine script names.

Programs can freely define the value of argv0 and thus it means nothing.
Instead, use the bash-specific variable explicitly designed to safely
and accurately reference the name of the currently sourced file.

This also fixes the case where simple debugging mechanisms like using
"bash -x foo" tried to treat "foo" as the unqualified $0 and therefore
broke horribly due to lack of pathnames.
