+++ This bug was initially created as a clone of Bug #533654 +++

The goal of this issue is to allow specifier to define new kind of "Select All" actions such as:
* All elements with same mapping: Select all diagram elements that have the same mapping than the current selected diagram element
* All elements of same type: Select all diagram elements that have a semantic target with the same type than the current selected diagram element
* All elements of type...: Select all diagram elements that have a semantic target with the type chosen by the end-user
* All elements corresponding to expression...: Select all diagram elements returned by an expression written by the end-user
* All "specified elements in odesign" : Select all diagram elements corresponding to a specific request defined by the specifier

These actions need to be available in the contextual menu and in the tabbar.

This enhancement depends on other enhancements:
* bug 529992: Improve Sirius Popup Menu contributions
* bug 533318: Add standard diagram services to avoid duplicated code

It will probably not modify the code but only give an example to exploit what will be done in the other issues.
