Moving unused code out of the kernel into Termops.
Strangely enough, the checker seems to rely on an outdated decompose_app
function which is not the same as the kernel, as the latter is sensitive
to casts. Cast-manipulating functions from the kernel are only used on
upper layers, and thus was moved there.
