* libc/include/sys/_types.h (_flock_t): Added.
        * libc/include/sys/lock.h (__lock_try_acquire): New interface.
        (__lock_try_acquire_recursive): Ditto.
        * libc/include/sys/reent.h (__sFILE, __sFILE64): Add new
        _lock field.
        * libc/stdio/findfp.c (std)[!__SINGLE_THREAD__]: Initialize _lock
        field.
        * libc/stdio/fopen.c (_fopen_r)[!__SINGLE_THREAD__]: Ditto.
        * libc/stdio64/fopen64.c (_fopen64_r)[!__SINGLE_THREAD__]: Ditto.
        * libc/sys/linux/include/time.h (struct timespec): Moved from
        <sys/types.h> and added check for __need_timespec flag so type
        can be defined by itself.
        * libc/sys/linux/sys/_types.h (_flock_t): New type.
        * libc/sys/linux/sys/types.h (struct timespec): Moved to
        <time.h>.
