[issue29838] Check that sq_length and mq_length return non-negative result

Serhiy Storchaka added the comment: Mis-behaving classes have to be written in C. If the __len__ method in Python class returns a negative value, ValueError is raised in slot_sq_length(). PySequence_GetItem() already contains an assertion that sq_length returns negative value only when an
