Avoid duplicate DNS requests if answer is longer than a implementation
limit [BZ #14307] * sysdeps/posix/getaddrinfo.c (gaih_inet): Increase the size of the temporary buffer used to invoke __gethostbyname2_r, __gethostbyaddr_r and gethostbyname4_r to make room for struct host_data / struct gaih_addrtuple. * resolv/nss_dns/dns-host.c (global scope): Move definition of implementation constants MAX_NR_ALIASES and MAX_NR_ADDRS to header file nss/nsswitch.h. * nss/nsswitch.h (global scope): Add definition of implementation constants MAX_NR_ALIASES and MAX_NR_ADDRS (moved from resolv/nss_dns/dns-host.c).
