* Optimize TableLongEncodingWriter

* Add checks to SerializerUtils methods

* Don't restrict byte order in SerializerUtils.writeLongToOutputStream() and writeIntToOutputStream()

* Update GenericIndexedBenchmark

* SerializerUtils.writeIntToOutputStream() and writeLongToOutputStream() separate for big-endian and native-endian

* Add GenericIndexedBenchmark.indexOf()

* More checks in methods in SerializerUtils

Roman Leventov 84fe91ba0b Monomorphic processing of TopN queries with 1 and 2 aggregators (key part of #3798) (#3889)
* Monomorphic processing: add HotLoopCallee, CalledFromHotLoop, RuntimeShapeInspector, SpecializationService. Specialize topN queries with 1 or 2 aggregators. Add Cursor.advanceUninterruptibly() and isDoneOrInterrupted() for exception-free query processing.

* Use Execs.singleThreaded()

* RuntimeShapeInspector to support nullable fields

* Make CalledFromHotLoop annotation Inherited

* Remove unnecessary conversion of array of ColumnSelectorPluses to list and back to array in CardinalityAggregatorFactory

* Close InputStream in SpecializationService

* Formatting

* Test specialized PooledTopNScanners

* Set flags in PooledTopNAlgorithm directly

* Fix tests, dependent on CountAggragatorFactory toString() form

* Fix

* Revert CountAggregatorFactory changes

* Implement inspectRuntimeShape() for LongWrappingDimensionSelector and FloatWrappingDimensionSelector

* Remove duplicate RoaringBitmap dependency in the extendedset pom.xml

* Fix

* Treat ByteBuffers specially in StringRuntimeShape

* Doc fix

* Annotate BufferAggregator.init() with CalledFromHotLoop

* Make triggerSpecializationIterationsThreshold an int

* Remove SpecializationService.PerPrototypeClassState.of()

* Add comments

* Limit the amount of specializations that SpecializationService could make

* Add default implementation for BufferAggregator.inspectRuntimeShape(), for compatibility with extensions

* Use more efficient ConcurrentMap's idioms in SpecializationService
