Mark internal nscd functions with attribute_hidden [BZ #18822]
Mark internal nscd functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * nscd/nscd-client.h (__nscd_get_map_ref): Add attribute_hidden. (__nscd_unmap): Likewise. (__nscd_cache_search): Likewise. (__nscd_get_nl_timestamp): Likewise. (__nscd_getpwnam_r): Likewise. (__nscd_getpwuid_r): Likewise. (__nscd_getgrnam_r): Likewise. (__nscd_getgrgid_r): Likewise. (__nscd_gethostbyname_r): Likewise. (__nscd_gethostbyname2_r): Likewise. (__nscd_gethostbyaddr_r): Likewise. (__nscd_getai): Likewise. (__nscd_getgrouplist): Likewise. (__nscd_getservbyname_r): Likewise. (__nscd_getservbyport_r): Likewise. (__nscd_innetgr): Likewise. (__nscd_setnetgrent): Likewise.
