Reworked how `tcpdump` picks up STDIN/STDOUT pipes. Converted from old-style socket pairs to modern `pipe` structures. Found that on 64-bit machines, `struct pcap_pkthdr` is not the same size as the similar array in the actual PCAP file. Added a new structure to compensate. Reworked `poll`, `write` and `read` to make them more robust. Works on Linux. Still haveing some issues on macOS.
