remove unused newQueue and delQueue

These functions were intended for callers who want to allocate a Queue on the
heap. However, this is unnecessary and callers all locate their Queue objects on
the stack and use mkQueue and freeQueue instead. This removal cleans up the code
a little and squashes two -Wmissing-prototypes warnings.
