To avoid ODR violation, the cc proto libraries (*.pb.cc) must be

statically linked to libtensorflow_framework.so, whereas cc grpc libraries
|
|
(*.grpc.pb.cc) must be statically linked to _pywrap_tensorflow.so.

To achieve this, Bazel rules are overridden to

(1) generate headers-only proto library, and
|
|
(2) build grpc library depending on the cc headers instead of the cc proto
|

library.
