  Modified files:
    include              unistd.h 
    lib/libc/gen         ttyname.3 ttyname.c 
    lib/libc_r/uthread   pthread_private.h 
  Log:
  Provide more POSIX-complaint ttyname_r(3) interface[1], which is slightly
  different from what has been offered in libc_r (the one spotted in the
  original PR which is found in libthr has already been removed by David's
  commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h):
          - Use POSIX standard prototype for ttyname_r, which is,
                  int ttyname_r(int, char *, size_t);
            Instead of:
                  char *ttyname_r(int, char *, size_t);
            This is to conform IEEE Std 1003.1, 2004 Edition [1].
          - Since we need to use standard errno for return code, include
            errno.h in ttyname.c
          - Update ttyname(3) implementation according to reflect the API
            change.
          - Document new ttyname_r(3) behavior
          - Since we already make use of a thread local storage for
            ttyname(3), remove the BUGS section.
          - Remove conflicting ttyname_r related declarations found in libc_r.
  
  Hopefully this change should not have changed the API/ABI, as the ttyname_r
  symbol was never introduced before the last unistd.h change which happens a
  couple of days before.
