Qt: Add extra related packet indicator types.

Add the ability to set frame number types: none, request, or response.
Use the types to draw different related packet indicators in the packet
list.

Track the conversation in PacketListRecord. Use it to draw dashed lines
for unrelated frames.

Set frame number types for DNS and ICMP.

Instead of drawing a transparent QImage, alpha blend our foreground
color and draw directly in our painter. Blend more toward the foreground
color.

Add FRAMENUM_TYPE to checkAPIs.
