It inserted the new items one position after the given one and inserted all new items
at the same position resulting in the items being in the reverse order of the
input array.
It was decided to make these behavioural changes because this function has according to
https://codesearch.debian.net/search?q=g_list_store_splice only one real user (nautilus)
and it didn't do what one would expect from reading the documentation.

GListStore already has a g_list_store_insert_sorted function,
which can be used to keep the list sorted according to a fixed
sort function. But if the sort function changes (as e.g. with
sort columns in a list UI), the entire list needs to be
resorted. In that case, you want g_list_store_sort().

GListStore requires that item-type be derived from GObject, so specify
that the type of the item parameters is GObject so the functions can be
used via gobject-introspection.
Add a scope parameter for the callback used during insert_sorted.
Add g_list_store_insert_sorted() which takes a GCompareDataFunc to
decide where to insert. This ends up being a very trivial function,
thanks to GSequence.

GListModel is an interface that represents a dynamic list of GObjects.
Also add GListStore, a simple implementation of GListModel that stores
all objects in memory, using a GSequence.
