* sysdeps/sh/tcb-offsets.sym: Add PRIVATE_FUTEX.
* sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h: Include endian.h.
Split __flags into __flags, __shared, __pad1 and __pad2.
* sysdeps/unix/sysv/linux/sh/libc-lowlevellock.S: Use private
futexes if they are available.
* sysdeps/unix/sysv/linux/sh/lowlevellock.S: Adjust so that change
in libc-lowlevellock.S allow using private futexes.
* sysdeps/unix/sysv/linux/sh/lowlevellock.h: Define
FUTEX_PRIVATE_FLAG. Add additional parameter to lll_futex_wait,
lll_futex_timed_wait and lll_futex_wake. Change lll_futex_wait
to call lll_futex_timed_wait. Add lll_private_futex_wait,
lll_private_futex_timed_wait and lll_private_futex_wake.
(lll_robust_mutex_unlock): Fix typo.
* sysdeps/unix/sysv/linux/sh/pthread_barrier_wait.S: Use private
field in futex command setup.
* sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S: Use
COND_NWAITERS_SHIFT instead of COND_CLOCK_BITS.
* sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S: Likewise.
* sysdeps/unix/sysv/linux/sh/pthread_once.S: Use private futexes
if they are available. Remove clear_once_control.
* sysdeps/unix/sysv/linux/sh/pthread_rwlock_rdlock.S: Use private
futexes if they are available.
* sysdeps/unix/sysv/linux/sh/pthread_rwlock_timedrdlock.S: Likewise.
* sysdeps/unix/sysv/linux/sh/pthread_rwlock_timedwrlock.S: Likewise.
* sysdeps/unix/sysv/linux/sh/pthread_rwlock_unlock.S: Likewise.
* sysdeps/unix/sysv/linux/sh/pthread_rwlock_wrlock.S: Likewise.
* sysdeps/unix/sysv/linux/sh/sem_post.S: Add private futex support.
Wake only when there are waiters.
* sysdeps/unix/sysv/linux/sh/sem_wait.S: Add private futex
support. Indicate that there are waiters. Remove unnecessary
extra cancellation test.
* sysdeps/unix/sysv/linux/sh/sem_timedwait.S: Likewise. Removed
left-over duplication of __sem_wait_cleanup.
