Noncopyable types do explicitly block copying operations

[mloskot]

At large, GEOS types which mostly are not ​copy constructible, do not block copy operations explicitly. A compiler is free to generate implicit ones which by default are public. It mismatches noncopyable contract with actual type implementation.

In order to fix it, declare (not define) private assignment operator and copy constructor.

Fixed in trunk in ~30 commits from r2759 to r2789 along with other minor improvements. (Commits in chunks to not to kill OSGeo Trac server.)

• Compilation and tests run using Visual C++ 9.0 and GCC 4.4.1
• This fixes clean more than 2000 warnings thrown by Visual C++ 8.0+
• Compilation now gives no GEOS specific warnings
• Number of Windows/Visual C++/STL/DLL specific ones - ​C4251:

   warning C4251: 'geos::geom::Point::coordinates' : 
     class 'std::auto_ptr<_Ty>' needs to have dll-interface to be used by
        clients of class 'geos::geom::Point'
  

If anything got broken here, please reopen.

The changeset r2790 confirmed as no warnings snapshot using:

• GCC 4.4.1 (-pedantic -ansi -Wall --Wno-long-long)
• Visual C++ 9.0 (with /W4 level)
