* inet/Makefile (routines): Add inet6_opt and inet6_rth. * inet/Versions (libc, GLIBC_2.5): Add inet6_opt_init, inet6_opt_append, inet6_opt_finish, inet6_opt_set_val, inet6_opt_next, inet6_opt_find, inet6_opt_get_val, inet6_rth_space, inet6_rth_init, inet6_rth_add, inet6_rth_reverse, inet6_rth_segments, and inet6_rth_getaddr. * inet/netinet/ip6.h (struct ip6_rthdr0): Make ip6r0_addr a flexible array. * inet/netinet/in.h (struct ip6_mtuinfo): Define. Mark inet6_option_* interfaces as deprecated. Declare inet6_opt_init, inet6_opt_append, inet6_opt_finish, inet6_opt_set_val, inet6_opt_next, inet6_opt_find, inet6_opt_get_val, inet6_rth_space, inet6_rth_init, inet6_rth_add, inet6_rth_reverse, inet6_rth_segments, and inet6_rth_getaddr. * inet/inet6_opt.c: New file. * inet/inet6_rth.c: New file. * inet/netinet/icmp6.h: Pretty printing.
