Add limited support for reading pcap-ng files.

All sections of the file must have the same byte order, so that the
result of pcap_is_swapped() is the same throughout the file; all
interfaces in the file must have the same link-layer type and snapshot
length, so that pcap_datalink() and pcap_snapshot() can return a single
value for the entire file; and all interfaces must have the same time
resolution and offset.
