Move substitute extern declarations to end of file, so that they are
not read until after we've read the port-specific header file. In
particular this should make it safer to #include system headers for
inet_aton; in general it seems that the port header file ought to be
in a position to set definitions before we do stuff based on having
a definition or not.
