Add a "report a warning message" routine to the "report_err" code in libwsutil, and rename files and routines appropriately, as they don't only handle errors any more. Have a routine read_enabled_and_disabled_protos() that reads all the files that enable or disable protocols or heuristic dissectors, enables and disables them based on the contents of those files, and reports errors itself (as warnings) using the new "report a warning message" routine. Fix that error reporting to report separately on the disabled protocols, enabled protocols, and heuristic dissectors files. Have a routine to set up the enabled and disabled protocols and heuristic dissectors from the command-line arguments, so it's done the same way in all programs. If we try to enable or disable an unknown heuristic dissector via a command-line argument, report an error. Update a bunch of comments. Update the name of disabled_protos_cleanup(), as it cleans up information for disabled *and* enabled protocols and for heuristic dissectors. Support the command-line flags to enable and disable protocols and heuristic dissectors in tfshark.
