Add the macros %typemap_asfromcheck() %typemap_asfrom() that can be used to defined all the different typemaps for types where the As/From/Check methods are provided. All the basic type (int, char,...) typemaps are implemented using them. The std::string and std::complex<T> are reimplemented using the new %typemap_asfrom/check macros too. This helps to complete all the previously missing typemaps (consttab, varin, varout,..) and also ilustrates how to define the As/From/Check methods to use with the %typemap_asfrom/check macros. As a byproduct, the C complex typemap was added, and the file complex.i can be used to load the complex support for either C or C++. The original C++ std_complex.i is still there, and the corresponding C ccomplex.i too, if they need to be included explicitly. Also, the As/From methods are declared via %fragment, so, they can be reused as needed, and only appear in the wrapped code if they corresponding typemap is invoked, making the typemaps and the entire code shorter and simpler.
