Fix deduction of partially specialized template parameters

Browse source 
when the specialized parameter is non-trivial, used in a wrapped method
and the type to %template uses typedefs. For example:

  typedef double & DoubleRef;
  template <typename T> struct XX {};
  template <typename T> struct XX<T &> { void fn(T t) {} };
  %template(XXD) XX<DoubleRef>;

The type of the parameter in the instantiated template for fn is now correctly deduced
as double.

#2492 [python] Fix unused parameter warnings for self parameter in
generated C/C++ wrapper code.

Fix deduction of partially specialized template parameters when the specialized
parameter is non-trivial, used in a wrapped method and the type to %template uses
typedefs. For example:
typedef double & DoubleRef;
template <typename T> struct XX {};
template <typename T> struct XX<T &> { void fn(T t) {} };
%template(XXD) XX<DoubleRef>;
The type of the parameter in the instantiated template for fn is now correctly deduced
