Ok, this patch removes the privilege stuff we had in, unused, for some time.

Ok, this patch removes the privilege stuff we had in, unused, for some time.

The code was nice, but put in the wrong place (group mapping) and not
supported by most of the code, thus useless.

We will put back most of the code when our infrastructure will be changed
so that privileges actually really make sense to be set.

This is a first patch of a set to enhance all our mapping code cleaness and
stability towards a sane next beta for 3.0 code base

Simo.
