Mark internal grp/pwd/shadow functions with attribute_hidden [BZ #18822]
Mark internal grp/pwd/shadow functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/grp.h (__fgetgrent_r): Add attribute_hidden. (__getgrgid_r): Likewise. (__getgrnam_r): Likewise. * include/pwd.h (__getpwuid_r): Likewise. (__getpwnam_r): Likewise. (__fgetpwent_r): Likewise. * include/shadow.h (__getspnam_r): Likewise. (__sgetspent_r): Likewise. (__fgetspent_r): Likewise.
