Turn the code of "colorize_packet()" into a static routine that is given

a word to use in the progress dialog, and a flag indicating whether the
display filter is to be reevaluated or not, and:

	have "colorize_packet()" call that routine with "Colorizing" and
	FALSE as those arguments;

	have the filtering code call that routine with "Filtering" and
	TRUE as those arguments;

	add an exported routine to call that routine with "Reprocessing"
	and TRUE as those arguments, to use to re-generate the packet
	list and to re-filter the packets if a protocol preference has
	been changed.

Keep track of whether preferences are changed from their initial value
by a preferences file or a command-line option, or from their previous
value by the "Preferences" dialog box; have "prefs_apply_all()" only
call the "apply" callback for a module if they have.

Call "prefs_apply_all()" after the command-line arguments have been
parsed and after "OK" has been clicked in the "Preferences" dialog box,
to notify modules of preference changes if they've registered a callback
for that.

After "OK" has been clicked in the "Preferences" dialog box, if any
preferences have changed, call the reprocessing routine, as the summary
line for some frames and/or the current display filter's value when
applied to some frames may have changed as a result of a preference
change.  Do the same after "OK" or "Apply" has been clicked in the
"Display Options" dialog box (as it controls a protocol preferences
item.
