Boost's iterator.hpp is deprecated (just like std::iterator in C++17). It does nothing but pulling std::iterator into namespace boost and including standard headers 'iterator' and 'cstddef'. Therefore get rid of including iterator.hpp (it had no effect in Boost.Geometry anyway) and replace inheritance by lifting std::iterator's members into the derived class. Instantiating std::iterator is granted with lengthy warning messages by latest MSVC when compiling in C++17 mode.

Mention box/point/segment as helper-geometry explicitly
Removed all std geometries from geometries.hpp, geometry.hpp, multi.hpp - they have to be included explicitly
