Ismaël Mejía resolved AVRO-4281.
--------------------------------
Resolution: Duplicate
Superseded by AVRO-4298. The collection block-count cap for [php] has been
folded into that issue's fix (PR https://github.com/apache/avro/pull/3863),
which now provides a single complete protection against collection allocation
DoS: available-bytes validation, a heap-aware cap for zero-byte-element
collections, a structural cap, and bounded skip paths. Resolving this as a
duplicate/superseded; the PR here (closed) is superseded by #3863.
