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).
