Inserts @data into @seq using @cmp_func to determine the new
position. The sequence must already be sorted according to @cmp_func;
otherwise the new position of @data is undefined.
@cmp_func is called with two items of the @seq, and @cmp_data.
It should return 0 if the items are equal, a negative value
if the first item comes before the second, and a positive value
if the second item comes before the first.
Note that when adding a large amount of data to a #GSequence,
it is more efficient to do unsorted insertions and then call
g_sequence_sort() or g_sequence_sort_iter().
