Private callbacks and properties

[mabar]

Follow up of #30 and #31

Currently are private callbacks and properties supported only in final classes. To support them on any classes, following must be resolved:

• meta validation must distinguish between classes in hierarchy
• - for each method/property must be used declaring class, not current class
• - multiple private methods/properties with same name must work (binding needs classname for private methods/properties)
• - public and protected methods must be validated in context of both defining and overriding class (to find source of error as well as ensuring overriding method e.g. changing parameters count from 1 to 2 is not broken) - continues in Callbacks covariance and contravariance #56
• - public and protected properties should not allow to be redefined (or at least their rules cannot be changed) - continues in Fields invariance #55
• - private properties with same must enforce different field name to avoid collisions
• before call must be method/property binded to context of class which defines it
• ! ensure metadata specify exact source - it matters whether annotation/attribute was defined on parent or child class !

Private mapped properties and callbacks are supported in any class since c1d7940

Traits and interfaces support was not checked yet. And neither overriding of public/protected properties/methods.
