Introduce bk_err and bk_bool rather than using int for both of these.
This means that the function definition now specifies whether 0 means
no error, or whether it means false.
Refactor tests in order for the component or logic that they are testing to be contained into individual sub-tests instead of all tests being contained in one big test for the whole data structure.
Add testing for out-of-memory (OOM) conditions. This makes the source code now 100% covered.
Bug fix! A bug has been identified and fixed in the list data structure in the list_add_last function. This bug would occur when adding an item to the back of the list because the pointers were not being updated properly.
Minor Bug fix! A bug has been identified and fixed in the unordered_set, unordered_map, unordered_multiset, and unordered_multimap data structures in their respective unordered_xxx_put functions. This bug would occur in an out-of-memory condition, which would cause the size of the collection to increase without actually adding the new element to it.
