This code overused macros and could not be converted automatically. Instead a new sigctxt type had to be defined for each os/arch combination, with a common (implicit) interface used by the arch-specific signal handler code. [This CL is part of the removal of C code from package runtime. See golang.org/s/dev.cc for an overview.] LGTM=r R=r CC=austin, dvyukov, golang-codereviews, iant, khr https://golang.org/cl/168500044
