+Description: logind: fix session not added to gc and other memleaks
+ 1) Proactively add session to gc on its Release event in order to prevent
+ entire session's leaks in logind due to not adding closing sessions to gc;
+
+ 2) Fix small leak in session_free(), by freeing the reset_controllers ptr;
+
+ 3) Fix small leak in cgmanager glue code.
