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.

allows variable sized inputs and pads upon dequeue.  Added unit tests.

During testing, identified a small C++ bug where TensorMap slice fails if
the slice shape has a zero length somewhere.  For now, avoid this error by
checking the slice's size and returning early if the slice is empty
(this is the correct thing to do).

Also change DirectSessionTest to use the public Session constructor when
possible, to discourage use of DirectSession as anything but an opaque
object that implements the Session API.  The one exception is the experimental
API, which requires a known down_Cast.
