c8c16de167 Fix reverse iterators for Vector and Array (#6626)
This commit fixes two serious issues connected with reverse iterators:
1. Vector's rbegin/rend was incompatible with std::reverse_iterator::base();
2. Array's rend() was incorrect, it based on end() instead of begin().

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)

fd4c1b5ff7 Replace std::string and const char* CreateSharedString with string_view (#6315)
It is useful to be able to call CreateSharedString with a string_view.
A string_view can be implicitly converted from a std::string or a const
char*.  This means if string_view is available, we can use it instead of
both other functions and get all 3.

cb971eece8 [C++] Fix -Wnarrowing and -Woverflow due to signed bitfields on G++ ARM (#6163)
Older versions of GCC (at least on ARM) complain about narrowing conversions and
overflows when setting the reference index (defined as an 11-bit signed integer
bitfield) to -1:

```
error: narrowing conversion of '-1' from 'int' to 'short unsigned int' inside { } [-Wnarrowing]
error: conversion from 'short unsigned int' to 'short unsigned int:11' changes value from '65535' to '2047'
```

This is due to the signedness of integer bitfields (not explicitly signed or
unsigned) being implementation-defined. This addresses this issue by explicitly
defining the signedness of all the bitfields in `flatbuffers::TypeCode` in C++.

ab01ae1620 flatc should output a warning, when an attribute is attached more than once (#6146)
* Added missing EndTable() call to VerifyObject()

VerifyObject called VerifyTableStart() but not EndTable(). This made Verifier::VerifyComplexity() increase depth_ with each table, not with the depth of tables.

* Added Check to VerifyAlignment

* flatc should warn, when an attribute is attached more than once.

The assignment operator of the `buf_` member is deleted, we cannot call it from the assignment operator of the `TableKeyComparator` struct.
