It's our own modification of clist. We should have renamed it, to avoid symbol
conflicts on Win32 and AIX. GTK+'s GtkCList adds rows via the g_list_append, which
does *not* maintain a pointer to the end of the list. Each time an append is made,
the entire GList of rows is searched for the tail node.

For very large capture files, this exponential time became noticable.

Our modified GtkCList keeps track of the tail GList node and appends directly to
that.

Guy has submitted the changes to the GTK+ folks, but they have not integrated
his patches into GTK+. By a note I read on the mailing list, they seem to want
to wait until GTK+-1.4 is out so they can use the GQueue container, which apparently
is a GList that knows where its tail is.
