hurd: Fix link cthread/pthread symbol exposition.
* hurd/Versions (HURD_CTHREADS_0.3): Rename weak refs cthread_fork, cthread_detach, pthread_getattr_np, pthread_attr_getstack, cthread_keycreate, cthread_getspecific, cthread_setspecific to __cthread_fork, __cthread_detach, __pthread_getattr_np, __pthread_attr_getstack, __cthread_keycreate, __cthread_getspecific, __cthread_setspecific. * hurd/hurdsig.c (_hurdsig_init): Use __cthread_fork, __cthread_detach, __pthread_getattr_np, __pthread_attr_getstack, __cthread_t instead of cthread_fork, cthread_detach, pthread_getattr_np, pthread_attr_getstack. * sysdeps/mach/hurd/cthreads.c (cthread_keycreate): Rename to __cthread_keycreate. (cthread_getspecific): Rename to __cthread_getspecific. (cthread_setspecific): Rename to __cthread_setspecific. (__libc_getspecific): Use __cthread_getspecific instead of cthread_getspecific. * sysdeps/mach/hurd/libc-lock.h (__libc_key_create): Use __cthread_keycreate instead of cthread_keycreate. (__libc_setspecific): Use __cthread_setspecific instead of cthread_setspecific. * sysdeps/mach/libc-lock.h (__libc_key_create, __libc_setspecific): Likewise.
