When `C` calls a function that return/has an out string and it was overwritten by `C#` inherit class the `C` portion wasn't cleaning its copy. Now, when a `C` calls a `C#` delegate function, `Strings` that are `out` values or `return` values use a new marshaler (specific to this case) that uses Eina short lived strings (`Eina_Slstr`) instead of duplicating it with `strdup`, so at some point, the string passed to `C` is deleted. To do so, a `direction_context` (a new `Context` at `generation_contexts.hh`) was created. It is only used when a C# delegate is being called from C (so this context is only set in `function_definition.hh` and `property_definition.hh`, where it is set to `native_to_manage` to indicate that it is a native call to a managed function). When this `direction_context` is set and the `String` being marshaled is not marked with an `@move` tag and it is an `out` or `return` value, the new `StringOutMarshaler` (implemented at `iwrapper.cs`) is used (instead of `StringKeepOwnershipMarshaler`). When marshaling a managed data to native this marshaler uses eina short lived string (`Eina_Slstr`) that will be automatically deleted. This delete is bounded to "the loop of the current thread or until the clear function is called explicitly" as said at `src/lib/eina/eina_slstr.h`.
