  Fix multiple int2str coversion in function parameters

While evaluating the parameters of the module funtions (which can be up to 6) some of them can internally use pvar evaluation with conversion from int to str.
Shortly, multiple int2str may be before in a row. To avoid data overlapping, the int2str uses now a set of 7 rotating buffers (instead of a single one).
