This makes the main source code look a little cleaner, at the expense of background magic happening in the configure-generated config.h. But this magic was already happening for _GNU_SOURCE, __EXTENSIONS__ and the like. The only wrinkle is that newer versions of NcursesW cause ./configure to include "-D_XOPEN_SOURCE=600" as part of the compilation command line--on systems that support _XOPEN_SOURCE=700. The AC_DEFINE/AC_DEFINE_UNQUOTED macros automatically comment out any "#undef" lines in config.h, so the file lib/xopen_source.h works around this limitation. It is automatically included by config.h.
