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.

c27bc2d76f [C++] Add ParseJson(), Parser(Parser&&), update fuzzers (#6284)
- add a new method ParseJson to minimize failures during fuzzing
- add default (conditional) move-constructor for Parser
- add a new monster_fuzzer
- switch fuzzers to C++17 and `test/cpp17` generated code

77d57fd075 Cast to right type for reserved_ subtraction (#6167)
reserved_ is a size_t so ensure that the output of cur_ - buf_ is cast to that to avoid compiler warnings.

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.

https://groups.google.com/forum/#!topic/flatbuffers/OpxtW5UFAdg

* Added Check to VerifyAlignment

* Add GetStringView (Convenience function to get string_view from a String returning an empty string_view on null pointer) like GetString, GetCstring

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

flatc.exe -b duplicate.fbs
warning: duplicate.fbs(5, 36): warning: attribute already found: priority

* Add `const` keyword to the `operator-(const uoffset_t &)` function in

* Support reverse iterator in Vector

Introduced a new VectorReverseIterator type. We cannot directly use
`std::reverse_iterator<VectorIterator>` because the signature of
`operator*` and `operator->` in the VectorIterator class are not
standard signatures.

Also added `rbegin()`, `rend()`, `cbegin()`, `cend()`, `crbegin()`
and `crend()` in the Vector class.

ca417426c7 make flatbuffers::IsFieldPresent safer (#4988)
Give the vtable offset enum inside each table the name
"FlatBuffersVTableOffset" and base type voffset_t so it can be used as a
dependent type in IsFieldPresent. This makes that function slightly
safer since it prevents calling it with arbitrary, non-table types.
Now, the only way to use IsFieldPresent incorrectly is to create your
own type which does not inherit from flatbuffers::Table but has a
dependent voffset convertible type "FlatBuffersVTableOffset".
