Remove anything to do with the combiner from set configuration and removes any options/storage related to these such as the next expected packet.

Instead this is done using trace_set_combiner now, and the for the built-in combiners.h header. This is a lot more flexible and allows the users to specify there own combiner, and any number of options for it.
