Improved variadic parameter names expansion

Number the variadic parm names instead of not naming them.

Such as:
  template<typename... T> int variadicmix1(T... t) { return 20; }
  %template(variadicmix1) variadicmix1<A,B,C>;

Used to expand to:
  int variadicmix1(A T, B arg1, C arg2)
now:
  int variadicmix1(A t1, B t2, C t3)

Also test for generating duplicate parameter names which required
a fix in R. Also results in a few minor changes to parameter names
in generated R code.
