Check and define which classes in YARP are copiable

[Nicogene]

To improve the quality of the API we should define which object are copiable and for the one not copiable
define

MyClass(MyClass &rhs)  = delete;

The same thing for not movable

MyClass(MyClass &&rhs)  = delete;

[Nicogene]

Non copyable classes:

• Port
• BufferedPort
• Node
• Publisher
• Subscriber

[Nicogene]

Following http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rc-copy-virtual
All base classes should be not copyables for avoiding object slicing[1].
