pcap: Handle short writes in pcap_frame()
Currently pcap_frame() assumes that if write() doesn't return an error, it has written everything we want. That's not necessarily true, because it could return a short write. That's not likely to happen on a regular file, but there's not a lot of reason not to be robust here; it's conceivable we might want to direct the pcap fd at a named pipe or similar. So, make pcap_frame() handle short frames by using the write_remainder() helper.
