In flatbuffers, build_defs.bzl has been updated to have the
bazel rule `flatbuffer_cc_library` defined. Therefore, it should
be possible to build another application and using `flatbuffer_cc_library`
directly (by `load("@com_github_google_flatbuffers//:build_defs.bzl", "flatbuffer_cc_library")`)

However, when I tried to do the above, I saw the following errors in bazel:
```
ERROR: /root/.cache/bazel/_bazel_root/c27e9809996ce9a9c0ed8dd79ef0897b/external/arrow/BUILD.bazel:12:1: in deps attribute of cc_library rule @arrow//:arrow_format: target '@arrow//:runtime_cc' does not exist. Since this rule was created by the macro 'flatbuffer_cc_library', the error might have been caused by the macro implementation in /root/.cache/bazel/_bazel_root/c27e9809996ce9a9c0ed8dd79ef0897b/external/com_github_google_flatbuffers/build_defs.bzl:216:16
```

The reason for the bazel error was that `//:runtime_cc` and `//:flatc` does not have
the repo name prefixed.

By prefix `` the above bazel build error could be resolved.

This fix should help other programs to use flatbuffers directly through bazel.

Track and emit required FlatBuffers namespace imports in generated Go code.

Update Go code generator by moving most functionality into the generator class, to facilitate namespace tracking. (Note that the git diff in this combined commit may appear large due to this refactoring, but very little code was actually changed.)
Update Go code generator by tracking namespace imports when generating FlatBuffers code.
Update Go code generator by emitting package imports to correctly reference code in other FlatBuffers namespaces.
Create Go test that checks the usage of InParentNamespace objects (as defined in the example schema).
Create Docker test that checks the Go language port.
Fixes #4883
Fixes #3927

Individual commits:

* remove "static" from soon-to-be method functions
* move almost all functions into class as methods
* set current namespace and emit package names if needed
* track imported namespaces
* parent namespaces work
* docker test for go ^1.11
* update base image name for go docker test
* remove cerr debugging
* formatting fixes
* re-run generate_code.sh
* explicitly test namespace imports and usage

By avoiding redundant alignment+alloc checks (startVector does prep) and virtual calls
(by making the class final) in inner loops.

* Pulling in protobuf's faster UTF-8 encoder.

* Remove Utf8 unsafe code.

* Enable flatbuffer to initialize Parser from bfbs (#4283)

Now its possible to generate json data from bfbs data type and flatbuffers data
and visa versa.

* add deserialize functionality in parser from bfbs
* add small usage sample

* Fix build break

* Merge branch 'pr/1' into fix-issue4283

* Fix buildbreak

* Build monster_test.bfbs with --bfbs-builtins

Attribute flexbuffer has be included in bfbs. Only with this attribute test
will run. By initialization a parser by a bfbs the attribute has to be known
for this filed. monsterdata_test.golden has a flexbuffer field so parse would
fail.

* Fix generate_code.sh

* Revert automatic indent changes by IDE

* Auto detect size prefixed binary schema files

* Use identifier (bfbs) to detect schema files

* disable reproducible build warning due to date/time macros

* wrapped GCC pragmas in #ifdef _GNUC_

* removed __DATE__ and __TIME__ macros from flatc.cpp

* Add flatbuffer_cc library support

* Update flags so all the tests pass

Tests now all pass!

* Modify the tests to use the generated code

This should be a simple serialize/deserialize test of the new generated
code to make sure the bazel rules are doing something sane.

* Use generated monster_test.fb in testing/test.cpp

cmake drops it's generated code in tests/monster_test_generated.h
Instead of checking that in, let's generate it with bazel.

* Make grpc tests depend on monster_test_generated.h

* Remove redundant cmake dependency

This should address @aardappel's feedback.

* Run flatc for Android as well

This will fix the last travis.ci failure

* Add generated output folder and fix flags

* Move flatbuffers_header_build_rules to the library that uses it

* Use --cpp-ptr-type to fix android

Android was the only target using the STL emulation layer.  It needed
the --cpp-ptr-type flatbuffers::unique_ptr flag to work.  Add it!

* Roll back changes to use autogenerated monster_test_generated.

Flip tests/test.cpp to use the autogenerated file as well.

[net] Fix issue #5036 when write a double value into bytebuffer at big endian machine with unsafe mode. (#5076)

This runs a script in TravisCI that executes a bunch of small Docker image
scripts to test the language ports in isolated environments. This allows us to
test multiple language versions with little additional complexity.

Covers:

+ Java OpenJDK 10.0.2
+ Java OpenJDK 11.0.1
+ Node 10.13.0
+ Node 11.2.0
+ Python CPython 2.7.15
+ Python CPython 3.7.1
+ Rust 1.30.1

* Fix Java generator bug that ignores streaming: bidi attribute
Tests

* Java gRPC client streaming test

* Java gRPC Bidi Streaming Test

The use case is so we can batch compile a bunch of schemas, some which can depend on each other, without caring about their order.

Multiple calls of e.g. CreateString inside a call to a CreateTable
could cause those strings to end up in different locations in the
wire format, since order or argument evaluation is undefined.

This is allowed by the FlatBuffer format, but it is not helpful,
especially when debugging the contents of binaries, or comparing
against a "golden" binary for tests etc.

Now making sure that all the CreateTableDirect calls first serialize
sub strings/vectors before calling CreateTable.

Also made similar changes to the serialization of "binary schemas".

* Make the Parser independent from the global C-locale

* Set a specific test locale using the environment variable FLATBUFFERS_TEST_LOCALE

* Remove redundant static qualifiers

* Fixed double generated file name postfix

* Fixed missing file postfix on imports without reexports

Tests for third_party code are run out of the main workspace.  This
isn't an issue when the main workspace is the
com_github_google_flatbuffers workspace, but is an issue when you are
running the tests from another repository.

To reproduce, use "git_repository" to add flatbuffers to a project and
then run:
  bazel test @com_github_google_flatbuffers//:flatbuffers_test
