Handle capture options in pcap-less Wireshark in the commandline_ routines.
Get rid of the capture_option_specified and arg_error members of the
commandline_capture_param_info_t and commandline_param_info_t
structures, and have them be local variables in
commandline_early_options() and commandline_other_options(). Have
commandline_early_options() print the "sorry, Wireshark wasn't built
with pcap" and exit if -D was specified but Wireshark wasn't built with
pcap.
