Provide for per-protocol-tree data in the proto_tree code.

Put a hash-table of "interesting" fields in the per-proto-tree data.
The dfilter code records which fields/protocols are "interesting" (by which
I mean, their value or existence is checked). Thus, the proto_tree routines
can create special arrays of field_info*'s that are ready for the dfilter
engine to use during a filter operation.

Also store the "proto_tree_is_visible" boolean, renamed "visible", in
the per-proto-tree data.

Move epan_dissect_t to its own header file to make #include dependencies
easier to handle.

Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t*
as an argument.

epan_dissect_new() needs to be followed by epan_dissect_run() for the
dissection to actually take place. Between those two calls,
epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to
prime the empty proto_tree with the "intersesting" fields from the dfilter_t.
