A number of call sites allocate memory for a refspec array, populate its members with heap memory, and then free only the refspec pointer while leaking the memory allocated for the member elements. Provide a function for freeing the elements of a refspec array and the array itself. Caution to callers: code paths must be checked to ensure that the refspec members "src" and "dst" can be passed to free.
