* dir.c (dir_fileno, dirfd): support of Dir#fileno on Solaris 10.

Browse source 
Solaris 10 does not have dirfd, but the file descriptor of a
  directory is stored in the d_fd or dd_fd member in the DIR struct.
  Note that Solaris 11 has dirfd(3C).

* configure.in: checks for DIR.d_fd and DIR.dd_fd on Solaris 10.
