Changes the use of `LookupStruct` to `LookupCreateStruct` in
`ParseField` to also detect when collisions happen in namespaces.

Alongside --binary and --json, an additional
switch (--flexbuffers) can be passed to convert
data using FlexBuffers

Fixes build errors from using newer crate versions with an old Rust version.

* Adds XOPEN_SOURCE for PATH_MAX and POSIX 1993 for stat

These are the only two required extension for compilation of
flatbuffers using -std=c++11 instead of gnu++11.

* Sets _XOPEN_SOURCE to 600 and enable POSIX2001 for fseeko

The real position of a string is  calculated by using the indirect() method,
which should be based on parentWidth and not byteWidth, as it was implemented.

We are also fixing the flag BUILDER_FLAG_SHARE_STRINGS on FlexBuffersBuilder
that was set as '1', same value as BUILDER_FLAG_SHARE_KEYS.

* Draft with Array specialization (#5508)

* Array specialization + SFINAE to fold copy-paste (#5508)

* Add implicit specialization of Array<scalar> and Array<struct> (#5508)

- Tag dispatching is used for implicit specialization
- Array<scalar> and Array<struct> have different iterators and accessors
- Array<scalar> and Array<struct> have different Mutate() methods

* Add implicit specialization of Array<scalar> and Array<struct> (#5508)

- Tag dispatching is used for implicit specialization
- Array<scalar> and Array<struct> have different iterators and accessors
- Array<scalar> and Array<struct> have different Mutate() methods

* Java: Added access object for vector of struct and vector of tables.

* Java: Workarounds removed when accessing the union vector.

* Add element size parameter to __vector_as_arraysegment

Add element size parameter to __vector_as_arraysegment fixing issue where VectorAsBytes returns incorrect size span for multibyte element types.

* Update codegen

Update codegen and Table to return typed span.

* update test files

update test files

Also add a FlexBuffer constructor to simplify usage

Together with @Nullable, this allows users to use static analysis tools
like CheckerFramework to catch NPEs caused by unset fields.

* [C#] Fix retrieving enumeration vectors as arrays

* [C#] Don't generate CreateVectorBlock for enums

Use all of the available space in the buffer returned by ByteBufferFactory to allow the factory to keep a pool of larger than initialsize sized buffers. (#5500)

* [FlexBuffers][Java] Implementation of FlexBuffers API

This is the initial attemp to implement FlexBuffer on Java.

There is some limitations as compared to the C++ implementation:
  1 - No mutations implemented yet
  2 - Does not parse from json

Also, this initial implementation is not focused and performance, but
get the basics write. So there is many opportunities for optimization, for instance,
remove all enums, return CharSequence instead of Strings and object pooling.

* [FlexBuffers][Java] Optimizations and simplification of the Builder  API.

This change removes BitWidth enum in favor of static ints. Also
make all "reads" APIs closer to C++ implementation (try to cast or convert
as much as possible, assuming user knows what he is doing). Finally,
we remove the helper classes for building vectors and maps.

There is no official benchmarks, but the unit tests are running in less
than 50% for previous runs, which mean those optimizations are worth it.

* [FlexBuffers][Java] Fix Reference::asString behavior

There was a incorrect assumption that strings would be null-terminated, which
could lead to truncated strings. S now it relies size instead of null-termination.

-Wextra-semi-stmt warning when building with Clang 8.0.0. Update generated
files for testing

* add Name() for ForceCodec  interface

// ForceCodec returns a CallOption that will set the given Codec to be
// used for all request and response messages for a call. The result of calling
// String() will be used as the content-subtype in a case-insensitive manner.
//

* Update grpc.go

... to avoid assertion failure or invalid access due to invalid vector index

The packing/unpacking steps for Boolean values was failing because the
code expected numerical values. I overrode the functions for the Boolean
metatable to account for this. I also had to exclude the Boolean
metatable from the GenerateTypes helper function, as that was overriding
the Pack/Unpack functions defined in its metatable.

Added Linux bash script to run Lua tests from the command line.

Bug: google/flatbuffers#5379

Tested: Added Lua tests that were failing and are now fixed with the
code changes.
