Google's new protobuf code generator only supports protobuf
serialization/deserialization and let other code generators handle
RPC-related aspects.
This new code generator follows the change and can be used with
the new protobuf code generator.

gRPC has UNIMPLEMENTED status code that indicates a requested method
is not implemented. However ttrpc was returning codes.NotFound which
could be returned when a request entity was not there.
This fix changes the status code from codes.NotFound to
codes.Unimplemented to disambiguate and be more compatible with gRPC.
Fixes#80.

This is mostly a copy of the workflow from the github.com/containerd/typeurl
repository. After this we can remove travis.

ttrpc provides WithOnClose option for user and ttrpc will call the
callback function when connection is closed unexpectedly or the ttrpc
client's Close() method is called. containerd runtime plugin uses it
to handle cleanup the resources created by containerd shim.
But the ttrpc client's Close() is only trigger and the shim's cleanup
resource callback is called asynchronously, which might make part of
resources leaky. There is an example from containerd-runtime-v2 for
runc:
```happy
[Task.Delete goroutine] [cleanupCallback goroutine]
call ttrpc client.Close() -->
read bundle and call runc delete
delete bundle
```
If the cleanupCallback is called after deleting bundle, the callback
will fail to call runc delete. If there is any running processes, the
resource becomes leaky.
```unhappy
[Task.Delete goroutine] [cleanupCallback goroutine]
call ttrpc client.Close() -->
delete bundle
failed to read bundle and call runc delete
```
In order to avoid this, introduces the UserOnCloseWait to make sure that
the cleanupCallback has been called synchronously, like:
```
[Task.Delete goroutine] [cleanupCallback goroutine]
call ttrpc client.Close() -->
wait for callback
read bundle and call runc delete
<-- finish sync
delete bundle
```

This copies the codes and status package from grpc as it is the only references
to the grpc project from ttrpc. This will help ensure that API breaking changes
in grpc do not affect ttrpc.
