longer as of Go 1.5. In Go 1.5 or later user calls to _swig_makegostring will fail at link time. Instead, use goout and godirectorin typemaps to allocate strings in Go code. Change the Go typemaps support to ignore empty strings, so that we can define empty strings for regular types so that %apply will override the definitions for string types. Fix the gccgo code to wrap SwigCgoCallback around all godirectorin typemaps. Add a few newlines after typemap code so that the typemaps don't have to include them.
