too many dependencies, things get cluttered (and merging probably
gets problematic). Now new config will be "conf2".

The capability has been added for module to specify that they do not
like being unloaded.

config variables were not properly initialized

The output interface has been changed, but we do not yet utilize the
new interface. Also, it looks like a regression was introduced. But before
hunting it down, I'd like to make a commit (what also easys the regresion
hunt).

first step: adding object-type specifier to config statement table

... by moving code to stream.c. Thanks to the new design, new cases are
not really needed, resulting in cleaner code.

I also did a cleanup of header file usage as a side-activity.

so far, this is mostly some documentation, but I hope that during
the process of creating output modules out of it we will get good
questions and thus can extend the template. In any case, it should
be better than what we had so far...
