- Add a solution to provide fuzzer support for afl-fuzz and libfuzzer. - Add fuzz targets for Binary, Json and Xml encoder and decoder fuzzing. For afl-fuzz and libfuzzer. - Fix issues in encoders and decoders when unexpected exceptions are returned. The expectation is to return only ServiceResultException with BadDecodingError, BadEncodingError or BadEncodingLimitsExceeded. - Add a tool to create Testcases. - Add a tool to playback crashes and timeouts. - Solution is extensible with common files to discover new fuzz targets by reflection. New fuzz projects can share many files with the first project. - Breaking change: Fix how BinaryDecoder is used: Previously, calling close on the BinaryDecoder implicitly disposed the stream. Change behavior so that `using` pattern can be applied across the board.
