DEBUG: list: add DEBUG_LIST to purposely corrupt list heads after delete

LIST_DELETE doesn't affect the previous pointers of the stored element.
This can sometimes hide bugs when such a pointer is reused by accident
in a LIST_NEXT() or equivalent after having been detached for example, or
ia another LIST_DELETE is performed again, something that LIST_DEL_INIT()
is immune to. By compiling with -DDEBUG_LIST, we'll replace a freshly
detached list element with two invalid pointers that will cause a crash
in case of accidental misuse. It's not enabled by default.
