08943aa26f Flatbuffer C++ UnpackTo optimization for vectors of non-bool bytes. (#6154)
UnpackTo copies vector elements one-by-one, which can be very inefficient depending on the quality of the compiler optimizations performed. This change updates the operation for vectors of bytes that aren't enums to use 'std::copy', which is usually highly optimized.

vectors of types that are more than one byte can't be optimized in this way because of the endianness of the serialized bytes vs. the target architecture endianness.

vectors of enums can't be optimized because they are required to be static_cast into the appropriate enum type when stored in the vector.

vectors of bools can be optimized in most cases, but since the standard
allows std::vector<bool> template specialization for space-savings,
std::copy doesn't work on every implementation (looking at you
Microsoft). Thus, this optimization is skipped for vector<bool>.

For a specific example, this improves the latency of unpacking large buffers on the Hexagon DSP by about 10x.

fb4e1c34f9 Add CharToLower and CharToUpper into util.s (#6126)
This commit adds replacement of `::tolower` and `::toupper`.
Added CharToLower and CharToUpper routines reduce the number of cast operators

e5a8f76a4b [C++] Generate default member initializers for >= C++11 (#5989)
In >= C++11 mode, generate default member initializers instead of a
default constructor.

The new code is semantically equivalent, but will allow aggregate
initialization in C++20.

This is a different take on #5951.

a875d247ad only add native_include_files if object based api is enabled (#5886)
The native include files tag is intended to be used together with the object based api. A client which does not use the object based api should have no need to know about the additional include files needed for the object based api. The generated flatbuffers code without object api enabled should compile without the additional header files.

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.

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.

* Added the code to embed the binary schema to the source.
This is pulled forward from a old PR #5162 that will be closed.

* Update idl_gen_cpp.cpp

Added a small comment to trigger a new build. The build was failing in a strange location and doesn't look like it has anything to do with the code.

* Moved the EscapeAndWrapBuffer to util.cpp and did some formating.

* One more camelCases removed and renamed some variables.

* wrapped_line_xxx should have been passed as a const reference in the first place.

* Moved the bfbs embed sample to it's own file.

* Missed moving the namespace back.

* Moved the embedded bfbs to test.cpp instead of using a sample.

* Missed adding the generation of embedded bfbs to the build.

* See if this makes the build happier.

* Fixed a in-compatable cpp output of the generated header.

* Did some changes to reflect the code review comments.
1. Update the EscapeAndWrapBuffer to BufferToHexText and fixed a variable name.
2. Moved the include of the embedded binary schema to all the other includes.

* Moved some code to inline the instead of using a local variable.

* Moved the BufferToHexText back to be a inline function in util.h

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.

a8e800bd7c Add --force-empty-vectors option (#5653)
The rationale for this option is that JSON clients typically want empty arrays (i.e [] in the JSON) instead of missing properties, but not empty strings when the value isn't set.
--force-empty is kept as-is, i.e. it will force both empty strings and vectors.

de9aa0cdee Add basic Kotlin support (#5409)
* [Kotlin] Add kotlin generate code for tests and add
kotlin test to TestAll.sh

* [Kotlin] Add Kotlin generator

This change adds support for generating Kotlin classes.

The approach of this generator is to keep it as close
as possible to the java generator for now, in order
to keep the change simple.

It uses the already implemented java runtime,
so we don't support cross-platform nor js Kotlin yet.

Kotlin tests are just a copy of the java tests.

* Add optional ident support for CodeWriter

Identation is important for some languages and
different projects have different ways of ident
code, e.g. tabs vs spaces, so we are adding optional
support on CodeWriter for identation.

* [Kotlin] Add Documentation for Kotlin

* [Kotlin] Modify generated code to use experimental Unsigned types.
