event-dispatcher: Add an enumeration of default event hook priorities

Browse Source 
This scheme provides for an orderly execution of hooks as the priorities
are controlled from one single place. Enumeration is defined in such a
way that new items can be added easily.

All the event hooks are changed to get the priorities from this
enumeration.
