Revert "Add support for default connection"

This reverts commit 99e66611c0d81b5802fb8222bb8754c4f6fcf293.

I have several concerns about this patch:

1) The DEFAULT section has to list all of its own connection settings
instead of referring to another section.
2) If we use this patch, the DEFAULT section is not optional.

Those are my reasons for reverting the patch.
