Provide portable way to attach behaviors to a composite / base implementation for behaviors

[eclipse-faces-bot]

Implementing behaviors in a component library is currently not as easy as implementing components.

1) There is no abstract behavior base available 2) No common way to handle state saving like the StateHelper 3) No common way to attach a behavior to a component 4) No common, portable and easy way to attach a behavior to a composite

It would be a great goal to create a abstract base for behaviors, which fixes the common problems. In PrimeFaces, i developed it via:

• AbstractBehavior; base class which handles the attributes and state saving - similar to getStateHelper and PropertyKeys

https://github.com/primefaces/primefaces/blob/6_0/src/main/java/org/primefaces/behavior/base/AbstractBehavior.java

• AbstractBehaviorHandler; attach the behavior to the target component or composite; currently with a hack for Mojarra and MyFaces

https://github.com/primefaces/primefaces/blob/6_0/src/main/java/org/primefaces/behavior/base/AbstractBehaviorHandler.java

Example implemtation of p:ajax: https://github.com/primefaces/primefaces/blob/6_0/src/main/java/org/primefaces/behavior/ajax/AjaxBehavior.java https://github.com/primefaces/primefaces/blob/6_0/src/main/java/org/primefaces/behavior/ajax/AjaxBehaviorHandler.java
