context_tracking: Rename __context_tracking_enter/exit() to __ct_user_enter/exit()

The context tracking namespace is going to expand and some new functions
will require even longer names. Start shrinking the context_tracking
prefix to "ct" as is already the case for some existing macros, this
will make the introduction of new functions easier.
