Modern Netlink arrays encode their elements as repeated attributes of the same type rather than as children of an additional array container. Add an SNL callback that parses one nested element for each occurrence and appends it to a geometrically grown parser array. Retain the existing parray callback for protocols that use the legacy container form. Store the growth capacity in struct snl_parray, appended after its existing public count and items fields so their offsets remain stable on LP64 and ILP32. Require parser targets to be real snl_parray objects, and convert bitset, generic Netlink, and route multipath arrays accordingly. This avoids relying on layout aliases for private growth state. Add regression coverage for a nested bit array that grows beyond its initial allocation, while preserving replacement semantics when a legacy array target is reused.
