Mark internal nss symbols with attribute_hidden [BZ #18822]
Mark internal nss symbols with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. Tested on x86-64 with and without --disable-nscd. [BZ #18822] * grp/initgroups.c (__nss_group_database): Removed. (__nss_initgroups_database): Likewise. * nscd/gai.c (__nss_hosts_database): Likewise. * nss/XXX-lookup.c (DATABASE_NAME_SYMBOL): Likewise. * posix/tst-rfc3484-2.c (__nss_hosts_database): Likewise. * posix/tst-rfc3484-3.c (__nss_hosts_database): Likewise. * posix/tst-rfc3484.c (__nss_hosts_database): Likewise. * sysdeps/posix/getaddrinfo.c (__nss_hosts_database): Likewise. * nss/getXXent.c (INTERNAL (REENTRANT_GETNAME)): Add attribute_hidden. * nss/nsswitch.c (__nss_database_custom): Define only if USE_NSCD is defined. (__nss_configure_lookup): Use __nss_database_custom only if USE_NSCD is defined. * nss/nsswitch.h (__nss_database_custom): Declare only if USE_NSCD is defined. Add attribute_hidden. (__nss_setent): Add attribute_hidden. (__nss_endent): Likewise. (__nss_getent_r): Likewise. (__nss_getent): Likewise. (DEFINE_DATABASE): Declare __nss_##arg##_database.
