csharp: generate helper constructors for structs. Summary: C# does not have a literal form for structs (like C++'s {} aggregate initialization). Before this commit the user would need to explicitly instantiate a struct and assign the required values to it, like: eina.Size2D size; size.W = width; size.H = height; widget.SetSize(size); As a workaround, this commit generates helper constructor with parameters corresponding to the struct fields in the order they are declared. These parameters have default values if one does not want to explicitly initialize all fields directly. With these constructs, the above code could be translated to: widget.SetSize(new eina.Size2D(width, height)); It should be noted that the constructed struct will live on the managed memory (GC) instead of the stack. Test Plan: run "make check" Reviewers: felipealmeida Subscribers: cedric Differential Revision: https://phab.enlightenment.org/D5838 Signed-off-by: Cedric BAIL <cedric@osg.samsung.com>

efl_mono: Reorganize utility functions. Summary: Blacklist functions are all in the header/namespace blacklist. Helper functions returning strings (names) are in the name_helpers header. They act somewhat like "mini-generators". Helpers.hh was left with other kind of helper functions (checks, etc) that do not return strings.
