  1. Add support for no-capture and no-inject device flags. 

    Add PCAP_IF_NO_INJECT and PCAP_IF_NO_CAPTURE to the list of known device
flags.  In show_devices_and_exit() do not print a shorthand number for
and in find_interface_by_number() do not count no-capture devices.
Update description on the "-D" flag in the man page.
