Mark internal stdio functions with attribute_hidden [BZ #18822]
Mark internal stdio functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/stdio.h (__fcloseall): Add attribute_hidden. (__getline): Likewise. (__path_search): Likewise. (__gen_tempname): Likewise. (__libc_message): Likewise. (__flockfile): Likewise. (__funlockfile): Likewise. (__fxprintf): Likewise. (__fxprintf_nocancel): Likewise.
