Also, a `layout.c` internal version mutable_layout_next() that allows to modify layout entries and a shorthand to look up an entry by name, _layout_entry_by_name(). Use the new functions where applicable and the code is not dropped later in this train, and also to compare the layouts in flashrom_layout_read_from_ifd() in depth.
