This function makes a new variable and returns it. The {\em type}
indicates the type of the new variable (field {\em type}).
When the variable is not of type {\em e\_int}, {\em initvar()} is
called to initialize the variable. The {\em vu.i$\rightarrow$count}
field is set to one, indicating that the variable shall be used to
point to once used memory. All relevant pointers (to strings or lists)
are set to {\em NULL}.
