Introduce a frame_data flag "need_colorize" to indicate that coloring
rules need to be evaluated and set it for the GUI (not tshark). This
restores the original performance characteristics.
It additionally fixes a regression where the color filter name and
filter is not shown anymore in the tree (I guess it is related to the
edt->tree being NULL when re-selected, resulting in empty color_filter).
Remaining problems:
- Display filter cannot contain frame.coloring_rule.* fields. Code is
present to enable this, but then a method is needed to avoid an
expensive second calculation (which is why it is disabled).
- The columns are still not updated after coloring rule change.
- The two frame.coloring_rule fields in the tree are not updated when
the coloring rule is changed (e.g. Ctrl-1).
The last two issues were supposed to be fixed by the previous patch, but
there is probably some missing code... Tested with GTK and Qt.
