"p_get_proto_data()" should, if it finds an entry, return the pointer

supplied in the "p_add_proto_data()" call that created the entry, not
the pointer to the data structure that holds the protocol and data
arguments to "p_add_proto_data()" (the protocol is uninteresting, as
its value is the value supplied as the "proto" argument to
"p_get_proto_data()".

The "frame_proto_data" structure isn't needed outside the code that
handles it; remove its definition from "packet.h" and put it in
"packet.c".
