That is every Samba include file.

We know this - however Samba isn't (and wasn't) built with the idea that
plugins should be a primary focus.  As such, it's a bit of a mess - there
really is no simple interface to write to, if you every want to call any
internal Samba function (like DEBUG, or the lp code).
