a protocol tree; the column values. This includes stats-tree listeners. Have the routines to build the packet list, and to retap packets, honor those requirements. This means that cf_retap_packets() no longer needs an argument to specify whether to construct the column values or not, so get rid of that argument. This also means that there's no need for a tap to have a fake filter to ensure that the protocol tree will be built, so don't set up a fake "frame" filter. While we're at it, clean up some cases where "no filter" was represented as a null string rather than a null pointer. Have a routine to return an indication of the number of tap listeners with filters; use that rather than the global num_tap_filters. Clean up some indentation and some gboolean vs. gint items. svn path=/trunk/; revision=28645
