* nscd/Makefile (nscd-modules): Replace gethstbynm2_r with
gethstbynm3_r.
* nscd/gethstbynm2_r.c: Remove.
* nscd/gethstbynm3_r.c: New file.
* nscd/aicache.c (addhstaiX): Use __gethostbyaddr2_r instead of
__gethostbyaddr_r.
* nscd/gethstbyad_r.c: Generate __gethostbyaddr2_r function. Define
__gethostbyaddr_r compatibility wrapper.
* nscd/hstcache.c (cache_addhst): Add ttl parameter. Use it when
determining timeout of entry.
(lookup): Take new parameter and pass it to __gethostbyname3_r and
__gethostbyaddr2_r.
(addhstbyX): Pass reference to variable for TTL to lookup and
cache_addhst.
* nss/Versions [glibc] (GLIBC_PRIVATE): Export __nss_passwd_lookup2,
__nss_group_lookup2, __nss_hosts_lookup2, __nss_services_lookup2,
and __nss_next2. Remove __nss_services_lookup.
* nss/XXX-lookup.c: Name function now *_lookup2. Add new parameter.
Add compat wrapper.
* nss/getXXbyYY_r.c: Changes to call new *_lookup2 functions and
__nss_next2.
* nss/getXXent_r.c: Likewise.
* nss/getnssent_r.c: Likewise.
* nss/nsswitch.c (__nss_lookup): Add new parameter. If first function
does not exist in module, try the optional second name.
(__nss_next2): New function.
(__nss_next): Now wrapper around __nss_next2.
* nss/nsswitch.h: Adjust __nss_lookup prototype.
Declare __nss_next2.
Adjust definition of db_lookup_function type.
* nss/service-lookup.c: Define NO_COMPAT.
* include/netdb.h: Declare __gethostbyaddr2_r and __gethostbyname3_r.
* inet/ether_hton.c: Use __nss_next2 instead of __nss_next.
* inet/ether_ntoh.c: Likewise.
* sunrpc/netname.c: Likewise.
* sunrpc/publickey.c: Likewise.
* inet/getnetgrent.c: Likewise. Adjust calls to __nss_lookup.
* inet/gethstbyad_r.c (DB_LOOKUP_FCT): Change to __nss_hosts_lookup2.
* inet/gethstbynm2_r.c (DB_LOOKUP_FCT): Likewise.
* inet/gethstbynm_r.c (DB_LOOKUP_FCT): Likewise.
* inet/gethstent_r.c (DB_LOOKUP_FCT): Likewise.
* nscd/aicache.c (addhstaiX): Fix default TTL handling.
* inet/getnetgrent.c (setup): Encrypt static pointer.
