Update.
* init.c (pthread_functions): New variable. (__pthread_initialize_minimal): Pass pointer to pthread_functions (or NULL) to __libc_pthread_init. * forward.c: Rewrite to use __libc:pthread_functions array to get function addresses. * sysdeps/unix/sysv/linux/fork.h: Remove __libc_pthread_init prototype. * sysdeps/unix/sysv/linux/libc_pthread_init.c (__libc_pthread_init): Take new parameter. Copy content of variable pointed to by it to __libc_pthread_init. * pthreadP.h (struct pthread_functions): New type. (__libc_pthread_init): Declare. * pthread_attr_destroy.c: Add namespace protected alias. * pthread_attr_getdetachstate.c: Likewise. * pthread_attr_getinheritsched.c: Likewise. * pthread_attr_getschedparam.c: Likewise. * pthread_attr_getschedpolicy.c: Likewise. * pthread_attr_getscope.c: Likewise. * pthread_attr_setdetachstate.c: Likewise. * pthread_attr_setinheritsched.c: Likewise. * pthread_attr_setschedparam.c: Likewise. * pthread_attr_setschedpolicy.c: Likewise. * pthread_attr_setscope.c: Likewise. * pthread_cond_broadcast.c: Likewise. * pthread_cond_destroy.c: Likewise. * pthread_cond_init.c: Likewise. * pthread_cond_signal.c: Likewise. * pthread_cond_wait.c: Likewise. * pthread_condattr_destroy.c: Likewise. * pthread_condattr_init.c: Likewise. * pthread_equal.c: Likewise. * pthread_exit.c: Likewise. * pthread_getschedparam.c: Likewise. * pthread_self.c: Likewise. * pthread_setcancelstate.c: Likewise. * pthread_setschedparam.c: Likewise. * pthread_mutex_destroy.c: Likewise. * pthread_mutex_init.c: Likewise. * pthreadP.h: Add prototypes for the aliases.
