Hello.

After fiddling with that, I decided to come up with reworked first part
of the patch and eventual translation to a more hierarchical structure
is subject for discussion.

This first patch adds default for couple of dump functions and it helps in future
to transform 0 to a TDF_NONE (or whatever we call it).

Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

Ready to be installed?
