Subject: move the complete functionality of the capture info dialog from
 capture_loop.c to capture_info.c and call it from capture.c (instead of
 capture_loop.c).

This way, the capture child don't need to now any of the packet_counter things (no epan/packet.h and all alike).

Currently the capture_info code will always open another wiretap file instance to build it's own counter values. This isn't optimized for now (next step: use data from cf_continue_tail() somehow).
