getopt: merge _GL_UNUSED annotations from gnulib
gnulib now has annotations on at least some functions to cater to compilation with -Wunused-parameter. In order to follow suit cleanly, I've added to libc-symbols.h some of the _GL_* macros that gnulib-common.m4 puts into config.h. (I don't think they belong in sys/cdefs.h, at least not without further thought.) At this point all gnulib-side changes to getopt.c have been merged. * include/libc-symbols.h: For gnulib compatibility, define _GL_UNUSED, _GL_UNUSED_LABEL, _GL_ATTRIBUTE_PURE, and _GL_ATTRIBUTE_CONST. * posix/getopt.c (_getopt_initialize): Mark argc and argv parameters with _GL_UNUSED.
