82836a62be [idl_parser] Improve stack overflow protection (#6364)
* [idl_parser] Improve stack overflow protection

Add stack overflow protection for Flexbuffer and nested Flatbuffer parsers.
Replaces the `Recurse()` method by the new ParseDepthGuard RAII class.

* Remove move operator from Parser.

It was wrong decision to add move ctor and assignment into Parser class.
These operators will make it extremely difficult to add constant or reference fields in the future.

* Remove ';' from definition of FLATBUFFERS_DELETE_FUNC

* Format code

* Make this PR compatible with MSVC2010 (it doesn't support inherited ctor)

92a806b4e8 [fuzzer] Rename fuzzing dictionaries for oss-fuzz (#6318)
This commit makes the names of fuzzing dictionaries the same as the target binary names.
Also it explicitly limits size of test inputs to prevent failures in `regex` and fuzzing time-outs.

9b034eee12 Fix interpretation of 'nan(number)' by the idl_parser (#5810)
* Parser reject "nan(n)" string as it does with nan(n)

* Adjust scalar fuzzer to ignore '$schema' substrings

- Scalar fuzzer ignores '$schema' substrings at the input
- Added 'scalar_debug' target to simplify research of fuzzed cases

* Improve formatting of './tests/fuzzer/CMakeLists.txt'
