[0/10] RFC: use gnulib more heavily + more configure fixes

Here's the patch series to rely more heavily on gnulib.

Some of these patches move to using a gnulib module and delete some
corresponding gdb_*.h file.

Others just remove useless configury junk.

I tested by building each patch (cumulatively; while they are
conceptually independent, in practice if you try to rearrange them you
will get conflicts) on an x86-64 Fedora 16 box. Of course, this is the
machine least likely to show any problems, but that's what I've got.

I did a "make check" of the series as a whole just to be sure.

More is possible here. I didn't try to touch perror or strerror; we
could also perhaps use the gnulib socket-related modules; and maybe more
as well.

Let me know what you think.
