Gimp/app/core/gimpimage-undo-push.c
Jehan bcacf6e2ae app: "active item" concept => "selected items". 
After much thought, tests and discussions with Aryeom, we decided adding
back an active item concept additionally to the selected items ones is a
bad idea as it makes only usage unecessarily complex.
We will just have selected layers. Some kind of operations will work
when more than one item (layers, channels, vectors) are selected while
others will require exacty one item.

In particular, let's replace instances of gimp_image_(s|g)et_active_*()
by corresponding gimp_image_(s|g)et_selected_*(). Also replace single
item in various undo classes by GList of items.
Also "active-*-changed" GimpImage signals are no more, fully replaced by
"selected-*s-changed".

This is still work-in-progress.
