        * libc/include/pthread.h: New file.
        * libc/include/sys/sched.h: New file.
        * libc/include/sys/features.h: New file.

        timespec, and struct itimerspec.  Centralizing these makes
        things cleaner.  RTEMS uses 64-bit dev_t.

        for pthreads including macros, pthread_attr_t,
        pthread_mutexattr_t, pthread_condattr_t, pthread_key_t,
        pthread_once_t, and pthread_t.

        If RTEMS follow POSIX on read(), write() and sbrk() prototype.
        Feature flags removed and moved to new file <sys/features.h>.
        Full set of POSIX sysconf() constants
