Remove useless cursor parameter to global undo actions

Add a Cursor-less version of Undo::recordUndoBufferParams (we don't
use an optional arument to avoir #includ'ing Cursor.h).

The version with CursorData parameter has been kept for the case of
local dictionary lfuns that have some kind of locality.

Remove Cursor argument to Undo::recordUndoFullBuffer().
