Mark internal utmp functions with attribute_hidden [BZ #18822]
Mark internal utmp functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/utmp.h (__updwtmp): Add libc_hidden_proto. (__getutent): Likewise. (__getutid): Likewise. (__getutline): Likewise. (__pututline): Likewise. (__getutent_r): Likewise. (__getutid_r): Likewise. (__getutline_r): Likewise. (__utmpname): Add attribute_hidden. (__setutent): Likewise. (__endutent): Likewise. * login/getutent.c (__getutent): Add libc_hidden_def. * login/getutent_r.c (__getutent_r): Likewise. (__pututline): Likewise. * login/getutid.c (__getutid): Likewise. * login/getutid_r.c (__getutid_r): Likewise. * login/getutline.c (__getutline): Likewise. * login/getutline_r.c (__getutline_r): Likewise. * login/updwtmp.c (__updwtmp): Likewise.
