* 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).

Consider TTL of CNAME record and return minimum TTL in the chain
...
[BZ #13928 ] A DNS request consists of multiple resources combined into
a single hostent, including multiple CNAME records that may have been
assigned different TTL values. In such a case, nscd should take the
least TTL among all of the resources as the timeout for the hostent
before it is reloaded in its cache so that the hostent remains stale
in the database for the least amount of time.

buflen.
