* Set default initialSize for Builder to 0

* Change default size of builder to 1024.

This matches what the C++ and Java versions do.

* Updated comments and fixed a fundemental type error.

* bump rust flatbuffers semver

* Initial commit with verifier, need to clean up

* Verifier tested. Needs clean up and refactoring.

* Display for InvalidFlatbuffer and better errors for strings

* SimpleToVerify, some refactoring

* Combined VerifierType TableAccessorFuncBody into FollowType

* scrub todos

* Update Rust get_root functions.

There are 6 variants, with verifier options, default verifier options
and no verification "fast".

* Rename root fns

* inline

* Update to use thiserror

* fix for bad compiler

* improve error formatting

* Replace multiply with saturating_multiply

* saturating adds too

* Add docs disclaiming experimental verification system

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.

The flatbuffers::Parser::Parse() isn't an idempotent method for schema parsing.
This commit removes a wrong for-loop that tried to check the same schema twice.

This is fix for (https://oss-fuzz.com/testcase-detail/6251772204810240)

Prior to this commit the default C++ code generator was `c++0x`.
A code generated with `c++0x` code-gen might have a vulnerability (undefined behavior) connected evolution of enums in a schema. This UB could break the backward compatibility if previously generated code casts an unknown enumerator to enum type that knows nothing about future enumerators added to the schema.

The main differences between `c++0x` and `c++11`:

- generated enums use explicitly declared underlying type;
- generated object-API tables don't declare default ctor() explicitly, instead of it default data member initializers are generated.

Please use `flatc --cpp-std c++0x` option for backward compatibility with old compilers.

This commit unifies parsing of NaN values read
from .fbs and .json files by converting them to unsigned NaN.

* Documentation updates for Optional Scalars

* Updated Support

- 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

* Add --require-explicit-ids to require explicit ids

We just got bit by a well intentioned developer forgetting that field
order by default is the field index.  3 people missed it in review.

I'm looking at ways to make it harder to mess up.  We are requesting
that developers explicitly id all fields in tables.  Automatic (opt in
for others) enforcement of this will help the effort succeed.  This
patch adds a command line flag which lets the user require ids on all
fields in tables.

* Added docs to Compiler.md as well

* idl_gen_json_schema.cpp: Changed generation of array element types
#6175

* idl_gen_json_schema.cpp: Simplified indent generation as suggested by @vglavnyy
#6175

The lack of any type on the `ret` variable was causing our typescript compiler to complain.

* Formats files & adds licence

* Revert arrays

* Keeps array indentation as is

* Adds licence to code formatter

* Updates code generators

* Remove _POSIX_C_SOURCE and _XOPEN_SOURCE definitions when compiling on OpenBSD

* Only define _POSIX_C_SOURCE and _XOPEN_SOURCE for mingw/cygwin platforms

* Only define POSIX statements for mingw/cygwin/qnx platforms

* 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

* 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

duplicate.fbs:

namespace MyGame;

attribute "priority";

table Monster (priority:1, priority:2) {
}

root_type Monster;

* flatc should support --binary --schema with optional scalar fields.

This fixes 'error: Optional scalars are not yet supported in at least one the of the specified programming languages.' when calling flatc.exe --binary --schema with a schema containing optional scalars.

Versions of rules_go below 0.24 include platforms repository, which are lacking
definitions of os:macos, cpu:arm64 constraints.

This definitions are needed to properly select toolchains in latest
bazel.

* Union As Accessors for C#

* Changed loop to be compatible with older compilers

* errant change fix

Resets buffer without deallocating current pointer & Bumps version

This will return the finished internal buffer data as a span

Android build was dated, using the Android.mk approach. Current
project configuration on Android encourages the usage of CMake, so we
are updating the android project as an example on how to use either the
Java/Kotlin generate code or the native C++ one.
