This has no practical effect, as CUDA builds are always with nvcc, but
it lets us modify the build config rule
//third_party/gpus/cuda:using_nvcc so it returns true, rather than
false, for CUDA builds.

Bring back fast_cpp_protos bazel configuration and remove 64MB limit of protobufs. This speeds-up graph serialization by ~15x for users building TensorFlow from source.

Note that you can now install a faster pip binary for protobuf using the instructions
in https://github.com/tensorflow/tensorflow/commit/8ac009728db931ef3119a337bd23250c89bc7efe

This only affects building and running from within the bazel environment.

bazelrc template, since they don't actually do anything.
Change: 116606748

Checking for a specific crosstool_top directory doesn't work when TensorFlow
is a sub-module for a different project.

Update protobuf commit
Change: 114990608

Change: 112920860

Change 109922312
	Update dockerfiles and instructions.

	This CL does two things:
	* updates dockerfiles to use 0.6.0
	* updates the instructions for the new tag format.
Change 109920508
	Fix broken cast_op_test
Change 109919316
	Enforce converting to int64 for SparseTensor indices and shape
Change 109916130
	Fix imagenet for Python 3

	It needed some binary file modes and an iteritems -> items.
Change 109912827
	Enable fast c++ implementation in protobuf's python interface.

Base CL: 109922840

Change 109344341
	Teach ./configure about Python 3 (and other minor Python 3 issues)

	./configure now writes bazel.rc based on a bazel.rc.template, which gives us a
	place to tell bazel which version of Python we were using.

	Also fix a few tests whose Python 3 support had degraded.

	The only thing left before we have Python 3 support is

	  https://github.com/google/protobuf/pull/1023
Change 109343002
	Update ops.pbtxt to reflect 109321497.
Change 109342838
	Do memory deallocation outside the critical section in gpu_event_mgr.cc.
Change 109334210
	PTB LSTM example: use slicing instead of splitting the inputs.
Change 109332238
	Cleanup TensorBoard local development environment
Change 109331051
	Use __all__ in __init__.py to restrict exported modules

	Specifically, __all__ is now anything that (1) doesn't begin with an underscore
	and (2) isn't a non-whitelisted module.

	This fixes one tiny piece of b/25561952.  Specifically, the following no longer
	exist: tf.np, tf.math_ops, and tf.variables.  tf.ops and tf.tensor_util still
	exist but shouldn't; that will have to wait for a later CL.
Change 109327154
	tf.tuple allow Tensors to be passed in as control_inputs like tf.control_dependencies.
Change 109324239
	Make tf.control_dependencies(None) clear the control dependencies.
	Use that to prevent ops created for Variables to inherit the current
	control dependencies.

	This fixes issues when using ExponentialMovingAverages with control
	dependencies.
Change 109323719
	Added support for boolean tf.scatter_update.
