Mark internal stdlib functions with attribute_hidden [BZ #18822]
Mark internal stdlib functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. __realpath is hidden with libc_hidden_proto and libc_hidden_def since the exported realpath is an alias of __realpath. [BZ #18822] * include/stdlib.h (__random): Add attribute_hidden. (__random_r): Likewise. (__srandom_r): Likewise. (__initstate_r): Likewise. (__setstate_r): Likewise. (__erand48_r): Likewise. (__nrand48_r): Likewise. (__jrand48_r): Likewise. (__srand48_r): Likewise. (__seed48_r): Likewise. (__lcong48_r): Likewise. (__drand48_iterate): Likewise. (__setenv): Likewise. (__unsetenv): Likewise. (__clearenv): Likewise. (__ptsname_r): Likewise. (__posix_openpt): Likewise. (__add_to_environ): Likewise. (__realpath): Add libc_hidden_proto. (__ecvt_r): Likewise. (__fcvt_r): Likewise. (__qecvt_r): Likewise. (__qfcvt_r): Likewise. * misc/efgcvt_r.c (cvt_symbol_1): Add libc_hidden_def (local). * stdlib/canonicalize.c (__realpath): Add libc_hidden_def.
