reduce namespace pollution in netinet/udp.h the affected part of the header is responsible for providing both GNU and BSD versions of the udphdr structure. previously, the namespace-polluting GNU names were always used for the actual struct members, and the BSD names, which are named in a manner resembling a sane namespace, were always macros defined to expand to the GNU names. now, unless _GNU_SOURCE is defined, the BSD names are used as the actual structure members, and the macros and GNU names only come into play when the application requests them.
