* Rework enums in rust.
They're now a unit struct, rather than an enum. This is a
backwards incompatible change but the previous version had UB
and was also backwards incompatible so...
* Update and test sample rust flatbuffers
* Use bitflags crate to properly support rust enums.
Previously, the bitflags attribute was just ignored. This is a breaking change
as the bitflgs API is not like a normal rust enum (duh).
* variant_name() -> Option<_>
* repr transparent
* Reexport bitflags from flatbuffers
* Make bitflags constants CamelCase, matching normal enums
* Deprecate c-style associated enum constants

* Fix C/C++ Create<Type>Direct with sorted vectors
If a struct has a key the vector has to be sorted. To sort the vector
you can't use "const".
* Changes due to code review
* Improve code readability
* Add generate of JSON schema to string to lib
* option indent_step is supported
* Remove unused variables
* Fix break in test
* Fix style to be consistent with rest of the code
* Add option to not generate direct copy methods.
The direct copy methods generated by flatc utilize std::vector which isn't allowed on some embedded systems. Permit users of the compiler to not generate these methods so they don't have to be stubbed out.
* Update docs for no-cpp-direct-copy option.
* Fixed rust nested flatbuffers for tables other than self
* replaced lifetimes
* Use WrapInNameSpace and also update samples

Older versions of GCC (at least on ARM) complain about narrowing conversions and
overflows when setting the reference index (defined as an 11-bit signed integer
bitfield) to -1:
```
error: narrowing conversion of '-1' from 'int' to 'short unsigned int' inside { } [-Wnarrowing]
error: conversion from 'short unsigned int' to 'short unsigned int:11' changes value from '65535' to '2047'
```
This is due to the signedness of integer bitfields (not explicitly signed or
unsigned) being implementation-defined. This addresses this issue by explicitly
defining the signedness of all the bitfields in `flatbuffers::TypeCode` in C++.
* GRPC implementation for Typescript
* Fixes a couple of issues
* Finished implementing the typescript support for grpc
* Updated generated code
* Fixes CI
* Moved C++ to optional_scalars2 and added some tests.
Also deleted unused optional_scalars_generated.lobster
* Fixed whitespece in C++ gencode & fixed BUILD file
* Moved C++ onto optional_scalars2 in the .bat file

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.

* [C#] Fix and improve project files
* "net35" target included for Unity 5
* "net46" target included for Unity 2017
* "netstandard2.0" target included for Unity 2018 and general use
* "netstandard2.1" target included for Span<T> support
Included project properties for defining UNSAFE_BYTEBUFFER, BYTEBUFFER_NO_BOUNDS_CHECK, and ENABLE_SPAN_T conditional compilation symbols.
* Add documentation on building for C#
* 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.
https://groups.google.com/forum/#!topic/flatbuffers/OpxtW5UFAdg
* Added Check to VerifyAlignment
https://stackoverflow.com/questions/59376308/flatbuffers-verifier-returns-false-without-any-assertion-flatbuffers-debug-veri

flatc.exe -b duplicate.fbs

* [Python] Codegen SizeOf classmethod for structs
This codegens a `SizeOf()` classmethod for all structs since we can't
determine the size of a FlatBuffer generated struct from Python otherwise.
* [JS/TS] Codegen sizeOf static method for structs
This codegens a `sizeOf()` static method for all structs since we can't
determine the size of a FlatBuffer generated struct from JavaScript or
TypeScript otherwise.
Add static cast from float to double in flexbuffers.h to avoid implicit double promotion error. This error is surfacing during the tensorflow lite for microcontrollers build since we enabled -Werror and -Wdouble-promotion.
* ENABLE_SPAN_T doesn't require UNSAFE_BYTEBUFFER.
Change to ENABLE_SPAN_T that doesn't require UNSAFE_BYTEBUFFER.
* Selectable framework.
Changed target framework to allow selection of 2.0 or 2.1 (or higher)
* Added target framework version check.
* Add core test project.
* Added run on .Net Core.

Included project properties for defining UNSAFE_BYTEBUFFER, BYTEBUFFER_NO_BOUNDS_CHECK, and ENABLE_SPAN_T conditional compiler constants.
* Add documentation on building for C#
This commit adds replacement of `::tolower` and `::toupper`.
Added CharToLower and CharToUpper routines reduce the number of cast operators
that required for correct usage of standard C/C++ `::tolower/toupper` routines.
This optionally generates a static `getFullyQualifiedName()` function to get
the fully-qualified name of a type in JavaScript and TypeScript in a similar
fashion to the C++ codegen.
Related with issue #6113.
`(old_buf_size & 0xC0000000) != 0` checks if we can duplicate old_buf_size
and still be under 2GB (by checking if bit 30 or 31 is 1). This doesn't
allow buffers larger than 1GB.
The strategy now is to allocate a buffer with the maximum array size
when we detect that we are overflowing the 2GB.
Also changed default buffer size to 1024.
