Use specific binder's event handlersguppy_6.99.2guppy/6.99.26.99.2
Use specific binder's event handlers which allows you to bind a callback with an incoming event based on a pattern matching. This replace the global event listener and internal callback search algorythm which is now delegated to the binder. Clean unused constructor Bug-AGL: SPEC-1968 Change-Id: I4b22c003661189fb71498efc4d9021c1a54ae866 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
