which means we're already doing a "do something to the last row in the
packet list" operation on every frame we add to the list, so adding a
call to "gtk_clist_set_row_data()" won't make matters worse.
In addition, we already set one column in a row on a "change time
format" operation, so finding the row for a frame by calling
"gtk_clist_find_row_from_data()" doesn't turn a constant-time operation
into a linear-time operation, it just cranks the proportionality
constant up - it was quadratic before, alas, and it's still quadratic.
Adding calls to "gtk_clist_find_row_from_data()" to the "Find Frame" and
"Go To Frame" code does add an extra linear operation there, but those
operations shouldn't be common - and "Go To Frame", going to the last
frame on an ~100,000-frame big capture file, was quick, at least on my
450 MHz Pentium II machine, so maybe it won't be too bad.
And "select_packet()" either has to search the frame table for the frame
with the specified row number, or has to call "gtk_clist_get_row_data()"
to do that - the first is linear in the position of the frame in the
frame table, and the latter is linear in its position in the CList, and
the latter is less than or equal to the former, so the only thing making
it worse would be a change in the proportionality constant.
So it probably won't hurt performance by much.
Furthermore, if we add the ability to sort the display on an arbitrary
column, or to delete frames from the display - both of which are in the
wish list - storing the row number of the frame in the "frame_data"
structure won't necessarily work, as the row number can change out from
under us.
Therefore, reinstate the old way of doing things, where we associate
with each row a pointer to the "frame_data" structure for the row, using
"gtk_clist_set_row_data()".

the "Follow TCP Stream" displays; that means we can use the same GTK+
calls to set the scrollbar placement on them that is used to set it on
other widgets.
Keep a list of all the GtkScrolledWindows whose scrollbar placement we
control with the GUI preference item for that, and change them all when
the GUI preference item is changed (which means that the GUI preference
item now applies to the "Follow TCP Stream" window as well as to the
hex/ASCII panes).

destroy the data structure for that window, rather than doing so when
the "tree-unselect-row" signal catcher is unhooked from the tree view.
