insert_slice_clone can double drop if Clone panics.

Affected versions of this crate used ptr::copy when inserting into the middle of a Vec. When ownership was temporarily duplicated during this copy, it calls the clone method of a user provided element. This issue can result in an element being double-freed if the clone call panics. Commit 20cb73d...

insert_many can drop elements twice on panic

Affected versions of insertmany used ptr::copy to move over items in a vector to make space before inserting, duplicating their ownership. It then iterated over a provided Iterator to insert the new items. If the iterator's .next method panics then the vector would drop the same elements twice...
