fb96fadc20 [C#] Fix nested structs and arrays in Object API (#5765)
* [C#] Fix nested structs and arrays in Object API

The adds support for nested structs and fixed size arrays in the C#
Object API codegen which previously generated invalid code that wouldn't
compile.

- Nested structs would originally generate syntax errors due to adding an
  additional `.` to separate fields.
- Fixed size arrays of nested structs would originally generate code for
  the first field in the top most struct, and would lead to a compiler
  error due to referencing undefined variables.

* [C#] fix nested structs and arrays of structs.

* fix nested structs + arrays

* add table support

* Cleanup code

925fab6b15 [Java][FlexBuffers] Optimize Map access (#5735)
The original implementation of map access is very naive:
- Encode String to UTF8 byte[]
- Creates a new KeyVector
- Performs a binary search to find the key
- return value

So every access to the Map there was useless allocations of Keys and KeyVector
and complete encoding of the search key, which for most comparisons would be wasteful.

This changes completely removes the use of KeyVector and compute the key
positions on the spot. Besides that, it compares keys codepoint-by-codepoint,
avoiding unnecessary allocations and reducing encoding for most cases.

Some benchmarks result in a 2.75x speedup.

c37c989ed6 Correct calculation of vector element size (#5831)
Number of elements on the stack shouldn't affect the calculation
of ElemWidth(). Variable 'start' needs to be subtracted from the
loop variable 'i' to make indexing zero-based.

There is an additional unit test to pack nested vectors. Size of
the packed buffer *without* this fix is 798 and only 664 bytes
*with* the fix.

6b271b7ecb Fix Clang-trunk warnings about special members deprecated in C++20. (#5829)
For example:

    include/flatbuffers/reflection.h:365:8: error: definition of implicit copy
          constructor for 'pointer_inside_vector<flatbuffers::Table, unsigned char>'
          is deprecated because it has a user-declared copy assignment operator
          [-Werror,-Wdeprecated-copy]
      void operator=(const pointer_inside_vector &piv);
           ^

It's unclear why the old code wanted to declare a public `operator=`
without defining it; that just seems like a misunderstanding of the C++03 idiom
for deleting a member function. And anyway, we don't *want* to delete the
assignment operator; these are polymorphic types that do not follow value
semantics and nobody should ever be trying to copy them. So the simplest fix
is just to go back to the Rule of Zero: remove the declaration of `operator=`
and let the compiler do what it wanted to do originally anyway.
"The best code is no code."

Also, update the generated .h files.

Fixes #5649.

cd88e6b2aa [Java][FlexBuffers] Abstract buffer access from ByteBuffer (#5743)
To read and build flexbuffers on Java, one needs to wrap the data
using  ByteBuffer. But for the common case of having ByteBuffers
backed by arrays, accessing from a ByteBuffer might be inefficient.

So this change introduces two interfaces: ReadBuf and ReadWriteBuf.
It allows one to read and writes data directly on an array. It also allow
 other buffer implementations to be used with flexbuffers.

Another change is that FlexBuffersBuilder backed by array allows
the buffer to grow with the increase of the message size. Something
that could not be done with ByteBuffer.

54f8b787cb Fix memory leak on cpp object api (#5761)
Previously UnPack would allocate data with new and assign it to a
raw pointer. This behavior makes it possible for the pointer to be
leaked in case of OOM. This commit defaults to use the user specified
pointer (which needs to implement a move constructor, a .get() and a
 .release() operators), thus preventing these leaks.

d54af8cd43 [C++] Use strong enum type for vectors when scoped-enums is on. (#5750)
* [C++] Use strong enum type for vectors when scoped-enums is on.

These changes only apply when scoped-enums is on, and thus only
the C++17 tests show diffs.

This may break users who use 1) use scoped-enums and 2) use
vectors of enums.  However, it seems that this change should
have been made originally when scoped-enums were added.

Fixes #5285

* [C++] Put strong enum change also behind C++17 flag.

It actually only needs C++11 technically, but this is being done
to avoid breaking any existing users.

Tests were rerun, but produced no additional diffs, as expected.

* [C++] Forgot one location in which C++17 guard needs to go.

This commit produces no additional diffs in generated code.

* Use g_only_fixed_enums instead of scoped_enums.

It will still be possible to read buffers with this type, but the

aligned.

6da1cf79d9 [rust] Add use declarations to Rust-generated bindings for imported FB definitions (#5645)
* Bugfix for Rust generation of union fields named with language keywords

Looking at ParseField, it appears that in the case of unions, an extra field with a `UnionTypeFieldSuffix` is added to the type definition, however, if the name of this field is a keyword in the target language, it isn't escaped.

For example, if generating code for rust for a union field named `type`, flatc will generate a (non-keyword escaped) field named `type_type` for this hidden union field, and one (keyword escaped) called `type_` for the actual union contents.

When the union accessors are generated, they refer to this `type_type` field, but they will escape it mistakenly, generating code like this:

```
  #[inline]
  #[allow(non_snake_case)]
  pub fn type__as_int(&self) -> Option<Int<'a>> {
    if self.type__type() == Type::Int {
      self.type_().map(|u| Int::init_from_table(u))
    } else {
      None
    }
  }
```

Which will fail to build because the field is called `self.type_type()`, not `self.type__type()`.

* [Rust] Add crate-relative use statements for FBS includes.

At present if a flatbuffer description includes a reference to a type in
another file, the generated Rust code needs to be hand-modified to add
the appropriate `use` statements.

This assumes that the dependencies are built into the same crate, which
I think is a reasonable assumption?

* Revert "[Rust] Add crate-relative use statements for FBS includes."

This reverts commit d554d79fec.

* Add updated generated test files.

* Fixing Rust test harness to handle new includes.

Test binaries need to add references to generated code that's
transitively included.

This also has the knock-on in that this code (which is referenced by
include directives directly in the flatbuffer schema files) also needs
to be generated, hence the changes to generate_code.sh.

* Test harnesses expect test data to be checked in.

Put include_test2 files into the same directory as the include_test2
schema definition.

Update all code generation scripts (forgot the batch file from last
time).

Path updates in Rust test.

* Include updated generated code

* Address comments raised in PR

* Fix failing Rust tests.

* Previous merge clobbered this branch change.

Rare failures occur on AppVeyor in these functions; the failures appear
spurious.

a5d9d0f7d3 [C++17] Add Traits class for Tables and Factory function within it. (#5678)
* Include flattests_cpp17 in unit tests when C++17 build is enabled.

* [C++17] Generate generic table factory function.

1. For each table, generate a convenient free-standing factory
   function that allows creating the table in a generic way by
   specifying only the type.  This is the first change in a series
   of changes to make Flatbuffers generated C++ code more friendly
   to code bases that make use of C++ template metaprogramming
   techniques to manage the serialization process.  Example:

     Before :(

       // The name of the Flatbuffers type (and namespace) must
       // be hard-coded when writing the factory function.
       auto monster = MyGame::Example::CreateMonster(fbb, ...);

     After  :)

       using type_to_create = MyGame::Example::Monster;
       // No namespace needed on CreateByTagType.
       auto monster = CreateByTagType((type_to_create*)nullptr,
                                      fbb, ...);

   This feature requires building with C++14 or greater, and thus
   it is guarded behind --cpp-std >= c++17 in the flatbuffers C++
   generator.

2. Fix a CMake bug to include C++17 unit tests in test suite.

* [C++17] Replace standalone variadic factory function with type_traits.

Add a `type_traits` to each table class.  This `type_traits` can be
populated with various compile-time info about the table.  Initially,
we have the Create* function and type, but is extensible in the future.

* Remove empty line and fix stale comments.

* Rename type_traits to Traits and move fwd declaration.

* Fix parameter evaluation order issue and use lambda for scope.
