[RFC] Method of directory traversing

[Shigio Yamaguchi]

Hello,

I would like to remove find(3) support in libutil/find.c in the future,
because it is time-consuming to always maintain two kinds of codes.
Currently, method selection is like this:

        if find(1) exist then
                use find(1)
        else
                use dirent(3)

As the first step, I would like to change the priority of the method
selection.

        if dirent(3) exist then
                use dirent(3)
        else if find(1) exist then
                use find(1)
        else
                ERROR

Since I know that the config macros HAVE_DP_D_TYPE and HAVE_DP_D_NAMLEN
don't work in linux, I will throw them away.

In the future, method selection will be like this:

        if dirent(3) exist then
                use dirent(3)
        else
                ERROR

Any objection?
