Syntax error fixes parsing more elaborate parameter pack arguments

Browse source 
that are function pointers and member function pointers.

  template <typename... V> struct VariadicParms {
    void ParmsFuncPtrPtr(int (*)(V*...)) {}
    void ParmsFuncPtrPtrRef(int (*)(V*&...)) {}
    void ParmsFuncPtrPtrRValueRef(int (*)(V*&&...)) {}
    void ParmsFuncPtrRef(int (*)(V&...)) {}
    void ParmsFuncPtrRValueRef(int (*)(V&&...)) {}

    void ParmsMemFuncPtrPtr(int (KlassMemFuncs::*)(V*...)) {}

    void ParmsMemFuncPtrPtrRValueRef(int (KlassMemFuncs::*)(V*&&...)) {}
    void ParmsMemFuncPtrRef(int (KlassMemFuncs::*)(V&...)) {}
    void ParmsMemFuncPtrRValueRef(int (KlassMemFuncs::*)(V&&...)) {}
  };

  %template(VariadicParms0) VariadicParms<>;
  %template(VariadicParms1) VariadicParms<A>;

  Also in various other places such as within noexcept specifiers:

    template<typename T, typename... Args>
    void emplace(Args &&... args) noexcept(
        std::is_nothrow_constructible<T, Args &&...>::value);

#1863 Syntax error fixes parsing more elaborate parameter pack arguments that are
used in function pointers, member function pointers:
template <typename... V> struct VariadicParms {
void ParmsFuncPtrPtr(int (*)(V*...)) {}
void ParmsFuncPtrPtrRef(int (*)(V*&...)) {}
void ParmsFuncPtrPtrRValueRef(int (*)(V*&&...)) {}

void ParmsFuncPtrRValueRef(int (*)(V&&...)) {}
void ParmsMemFuncPtrPtr(int (KlassMemFuncs::*)(V*...)) {}
void ParmsMemFuncPtrPtrRef(int (KlassMemFuncs::*)(V*&...)) {}
void ParmsMemFuncPtrPtrRValueRef(int (KlassMemFuncs::*)(V*&&...)) {}
void ParmsMemFuncPtrRef(int (KlassMemFuncs::*)(V&...)) {}
void ParmsMemFuncPtrRValueRef(int (KlassMemFuncs::*)(V&&...)) {}
};
%template(VariadicParms0) VariadicParms<>;
%template(VariadicParms1) VariadicParms<A>;
Also in various other places such as within noexcept specifiers:
template<typename T, typename... Args>
void emplace(Args &&... args) noexcept(
std::is_nothrow_constructible<T, Args &&...>::value);

Fix instantiation of variadic class templates containing parameter pack arguments that
are function pointers.
