AVRO-4241: [Java] BinaryDecoder should verify available bytes before reading
(#3725)
* AVRO-4241: [Java] BinaryDecoder should verify available bytes before reading
Add ensureAvailableBytes() pre-check in readString, readBytes,
readArrayStart, arrayNext, readMapStart, and mapNext to verify the
source has sufficient data before proceeding.
Byte-array-backed sources return an exact remaining count.
Stream-backed sources return buffered bytes plus InputStream.available(),
which is reliable for the finite streams used by DataFileReader and
DataFileStream.
Includes regression tests and updated array/map limit tests.
* AVRO-4241: [Java] Simplify no-op validatioin code and fix possible int
overflow per PR comments
* AVRO-4241: Test the overhead of {@code minBytesPerElement} computation on
GenericDatumReader
Benchmark to measure the overhead of {@code minBytesPerElement} computation
during array/map decoding via {@link GenericDatumReader}. Tests complex, wide,
and recursive schema structures to verify that the per-block schema traversal
cost is acceptable.
