Retrieves a sufficient offset for an element of size size.

Returns a negative value if no offset is available. If an offset is available, it returns its value. The found offset is removed from the list and an offset is added for the remaining size if it is not zero: if the found offset is offset and the associated size is offset_size, call add(offset_size - size, offset + size).
