Have separate packet_provider_data structures and packet_provider_funcs structures; the latter holds a table of functions that libwireshark can call for information about packets, the latter holds the data that those functions use. This means we no longer need to expose the structure of an epan_t outside epan/epan.c; get rid of epan/epan-int.h.
