44b2ab087c include/flatbuffers/base.h: fix no_sanitize issue with old clang (#5610)
Older clang versions raise:
```
./flatbuffers/base.h:365:1: error: unknown attribute 'no_sanitize' ignored [-Werror,-Wattributes]
__supress_ubsan__("alignment")
^
./flatbuffers/base.h:246:50: note: expanded from macro '__supress_ubsan__'
  #define __supress_ubsan__(type) __attribute__((no_sanitize(type)))
                                                 ^
```

Comparing https://releases.llvm.org/3.6.0/tools/clang/docs/AttributeReference.html
with https://releases.llvm.org/3.7.0/tools/clang/docs/AttributeReference.html
shows that __attribute__((no_sanitize(type))) is available since 3.7.0

a1f14005ab Fix big-endian build. (#5205)
For some reason, Offset<T> is being considered a scalar, which
causes EndianSwap to be passed an Offset<T>.  This doesn't work,
as it does not support types with non-trivial constructors.  This
change adds an overload to WriteScalar(), which works around this.

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".

28920aff8f Fix build with clang on big-endian targets (#4440)
* flatbuffers: Move EndianSwap template to flatbuffers/base.h

Clang complains
call to function 'EndianSwap' that is neither visible in the template definition nor found by argument-dependent lookup
     return EndianSwap(t);

This seems to be due to limitation of two-phase lookup of dependent names in template definitions

Its not being found using associated namespaces therefore
it has to be made visible at the template definition site as well

* use __builtin_bswap16 when building with clang

a892322203 C++98 (stlport) support for core FlatBuffers and FlexBuffers.
* Added internal - limited - implementation of flatbuffers::unique_ptr
  for STLs that don't ship with std::unique_ptr.  In C++11 and beyond
  this is just an alias for std::unique_ptr.
* Aliased used type traits structs is_scalar is_floating_point is_unsigned
  into flatbuffers namespace so they can be replaced in C++98 implementations.
  Right now these point at stlport's TR1 implementations.
* Wrapped vector::data() in vector_data().
* Wrapped vector::emplace_back() in vector_emplace_back().
* Wrapper string::back() in string_back().
* Added variants of FlatBufferBuilder::CreateVector() and
  FlatBufferBuilder::CreateVectorOfStructs() that allow the use of plain
  function pointers.
  Generated code has also been modified to use plain functions to build objects
  rather than std::function() so all generated code will work in C++98
  applications.
* Added flexbuffers::Builder::Vector(), flexbuffers::Builder::TypedVector()
  and flexbuffers::Builder::Map() methods that allow the use of plain function
  pointers.
* Changed Parser to internally use plain function pointers when parsing table
  and vector delimiters.
* Added specializations of NumToString() for 64-bit types that aren't supported
  by stringstream in stlport.
* Overloaded numeric_limits for 64-bit types not supported by stlport.
* Replaced build_apk.sh (which was broken by deprecation of the
  "android" tool in the Android SDK) with build.gradle and the
  appropriate gradle wrapper to build an APK.
* Switched Android build to build against all STL variants.
* Updated travis configuration to build Android test and sample.

Tested:
* Verified all tests continue to work on Linux, OSX and Android.
* Verified Travis build is green.

da67c0a71f [C++] Improve flatbuffers + gRPC integration (#4310)
* Rework flatbuffers + gRPC integration

- Introduce `flatbuffers::grpc::Message<T>`, a `grpc_slice`-backed
message buffer that handles refcounting and allows flatbuffers to
transfer ownership to gRPC efficiently. This replaces
`flatbuffers::BufferRef<T>`, which required a copy call and was also
unsafe w.r.t. buffer lifetime.
- Introduce `flatbuffers::grpc::MessageBuilder`, a gRPC-specific builder
that forces a `grpc_slice`-backed allocator and also adds some helpful
`Message<T>`-related methods.
- Update serializers accordingly (now zero-copy between flatbuffers and
gRPC).

* gRPC: verify messages by default, but allow user to override

* gRPC: fix some formatting issues

* Disable verification by default, but add helper method

* Make FlatBufferBuilder fields protected + remove vec accessor

* Use bool add_ref parameter to toggle refcount incr

* Remove unnecessary inline specifiers

* Fix formatting

* Use auto

* Remove empty lines

* Use grpc_slice helper macros

* Simplify reset code

* Disable Message copy ctor and assignment by default

* Remove unused member

* Enable gRPC verification by default

* Use auto

* Bake in message verification (remove template specialization)

* Add RoundUp func

* Consolidate gRPC message copy flag

* Make vector_downward allocations fully lazy

* Test message verification failure code/message

* Add grpctest verification test comments

* Simplify reallocate implementation

* Make initial_size a size_t

* Use ternary op for growth_policy

* Use truthiness rather than dont explicit nullptr check

* Indent preprocessor directives

* Remove grpc message copy/assignment

* Fix a few bugs

* Add gRPC example

* Add basic gRPC docs

* Use doxygen EXAMPLE_PATH + @include

* Reference example fbs in grpc docs

* Move gRPC examples into grpc/samples

* Fix pointer/reference formatting

* Use std::function rather than templated callback func

* Create fresh message builder for each request

* Use Clear() in Reset() impl

* Use FLATBUFFERS_CONSTEXPR
