8b52af65bc [C++] Add max_depth and max_tables parameters to reflection::Verify (#5815)
* 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

StringToNumber will correctly use locale-insensitive functions
when available.

f0f0efe7b8 [C++] Refactor to conform to Google C++ style guide (#5608)
* Automatic refractor of C++ headers to Google C++ style guide

* Automatic refractor of C++ source to Google C++ style guide

* Automatic refractor of C++ tests to Google C++ style guide

* Fixed clang-format issues by running clang-format twice to correct itself. Kotlin was missing clang-format on after turning it off, so it was changed,

8f1bebba05 C++ verifier now primarily uses offsets instead of pointers.
Fix for: https://bugs.chromium.org/p/chromium/issues/detail?id=834710

Before, the verifier would create pointers to objects, and then
verify they are inside the buffer. But since even constructing pointers
that are outside a valid allocation is Undefinied Behavior in C++, this
can trigger UBSAN (with -fsanitize=pointer-overflow).

Now instead the bounds checking is first performed using offsets
before pointers are even created.

12c4c2238c Output JSON strings as natural UTF-8 text without escapes (#4710)
* Added support for the non-escaped print of utf-8 string.

* EscapeString: the first invalid symbol resets print_natural_utf8 flag to false.

* Move the test to ParseAndGenerateTextTest. Fixes.

* Removed dependence between `natural_utf8` and `allow_non_utf8` flags.

e93d2bda07 Cleaned up & fixed buffer alignment handling.
- Fixed ForceVectorAlignment (and possibly other call-sites) not
  setting minalign_.
- Fixed flipped alignment parameters in CopyTable (reflection).
- Made aligment for FlatBufferBuilder internal buffer configurable
  (useful when reading a constructed buffer directly).
- Ensured Alignment rounding is always up.

ac1015e3c4 Trimmed vtables of trailing zeroes.
This is something the format supports, but none of the builders
were doing. Can save 10-20% on FlatBuffer binary size!

Also fixed the Go tests.

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.

bbb72f0b73 Tweak fallthrough comments to get recognized by gcc7 (#4298)
GCC gained a new warning, -Wimplicit-fallthrough, which warns about
implicitly falling through a case statement. The regular expressions
used at the default level (-Wimplicit-fallthrough=3) don't match with
a colon at the end. The comment also needs to be followed (after
optional whitespace and other comments) by a 'case' or 'default'
keyword, i.e. it will not be recognized with a '}' between the comment
and the keyword.

6d6271db2f Changes for verifying a buffer dynamically using reflection. (#4102)
* Changes for verifying a buffer dynamically using reflection.

* Fixing build issues on linux and applied code reformatting.

* Fixing the file order in cmake file that was messing up the macro based code inclusion.

Added tests for reflection based verification.

* Changes for verifying a buffer dynamically using reflection.

Fixing build issues on linux and applied code reformatting.

Fixing the file order in cmake file that was messing up the macro based code inclusion.

Added tests for reflection based verification.

* Incorporated the code review changes that were requested:

1. Changed the Verify function signature.
2. Changed the variable names to use snake_case.
3. Added better comments.
4. Refactored duplicate code.
5. Changed the verifier class so that it has the same size when compiled with or without FLATBUFFERS_TRACK_VERIFIER_BUFFER_SIZE macro.

* Setting FLATBUFFERS_TRACK_VERIFIER_BUFFER_SIZE and FLATBUFFERS_DEBUG_VERIFICATION_FAILURE through cmake for flattests so that it gets propagted to all translation units of flattests.

* Making the Verifier struct fields the same in all cases. Also reverting the target_compile_definitions change in cmake file because build machine on travis does not have cmake version 3.0 or higher which was the version when target_compile_definitions was added in cmake.

* Defining macros through cmake in a portable way using functions that are available in cmake 2.8.
