epan: Add more bookkeeping for layers
Packet info already contains the notion of layer depth for the
current protocol, among all the protocols in the frame. This
adds an extra layer number for the protocols that are the same
as the current one. Obviously this will only go above one if
the protocol is repeated in the stack, such as with IP tunneling.
Adds extra logic to track numbers for each protocol in the frame
and update them when calling a dissector.
The total layer number and protocol layer number are store in
the field info structure so they can be used after dissection,
namely by display filters.
