Introduce resv_region_list_insert() helper which inserts a new ReservedRegion into a sorted list of reserved region. In case of overlap, the new region has higher priority and hides the existing overlapped segments. If the overlap is partial, new regions are created for parts which are not overlapped. The new region has higher priority independently on the type of the regions.
