Restore the ''import "unsafe'' removed in 36daedf3…

This was causing build failures with tools dependent on Flatbuffers in Go.
E.g.
go/src/github.com/google/flatbuffers/go/sizes.go:50: undefined: unsafe in unsafe.Pointer

* Create basic issue template

* Update ISSUE_TEMPLATE.md

Avoid unsafe when sizing types

Add a generic way to deserialize a flatbuffer in Go.

* support for grpc golang

* refactored grpc go generator

* added grpc-go test and refactored

* refactored idl_gen_grpc.cpp

* fixed grpc generate method name

* refactored flatc and fixed line length issue

* added codec to go lib and fixed formatting issues

* fixed spacing issues

The following changes have been made to the C++ codegen to enable writing generic code
that uses the Table and NativeTable types.

- Adds TableType and NativeTableType typedefs to NativeTable and Table structs.
- Adds GetFullyQualifiedName() to NativeTables if --gen-name-strings is set.
- Adds a static Pack function to Tables that simply calls the global CreateX functions.

See cr/140391505 as an example of improved usage.

Introduce a "native_inline" attribute that can be applied on fields that are structs.
This results in NativeTable code generation that sets the struct "inline" rather than
storing it in a pointer.

account underlying buffer's byte offset.

I've faced an issue where I want to serialize UTF-8 emojis and FlatBufferBuilder::is_utf8 would return false on them.
I was not able to add the corresponding hexadecimal code because I don't understand how the whole thing works but what i've done is using the `mb_detect_encoding` function which handles correctly all supposed UTF-8 characters.

Making flatbuffers JSON parsing deal with unexpected null values when unknown JSON is allowed. (#4083)

* chore(lint)

I accidentally let 2 pieces of lint in with my generated code.

* fix(generate-code): I did not generate all the required code for tests.

Fixed generation of a trailing comma and removed unnecessary use of a lambda.

Also fixed structs not being created inline in the tutorial,
which would actually have bad consequences if used.

* Make parameter order in jsdocs match function

When the order doesn't match the Google Closure Javascript compiler generates
warnings

* Prefix optional parameters with opt_

The Closure Compiler emits warnings when this isn't the case

* Java: emit "signed" equivalent of unsigned default value in generated code and add "L" suffix to long default value.

* Updated generated code

* Only convert ulong to "signed" equivalent. ubyte and ushort don't need specific handling as "user facing" type is int. uint need 'L' suffix as "user facing" type is long.

* Added missing cast to primitive type of default value which is in "user facing" type in builder.add<type>() calls.

* Do not cast default value to actual type in C#.

These are useful for streaming FlatBuffers. The functionality
ensures proper alignment of the whole buffer.

This allows hashed string fields to be used for lookup of any
C++ objects, a pointer to which are then stored in the object
besides the original hash for easy access.

flatc java generator: namespace_test2.fbs is missing namespace prefix for referToA2() return type (#4040)

* Fix flatc generating incorrect java/c# code for namespace_test2.fbs. In code for TableInC, method referToA2() returned type SecondTableInA instead of NamespaceA.SecondTableInA.

* Updated generated code.

* Fixed indendation.
