Adds tf.contrib.learn quickstart and tf-wide (and deep) stuff to tutorial left nav and index page (and fixes an URL in the wide overview). Also breaks the left nav and index page into sections, because the list of tutorials is getting long.

Change: 124970170

Change: 125205938

Version bump: 0.9.0rc0 --> 0.9.0

Updated feature_column to use string_to_hash_bucket_fast instead of deprecated string_to_hash_bucket.

Fixes to TensorArray and Functional ops

Fix genrule Python execution problem with Python3.

- TensorArray shape inference now works correctly for scalar elements
- TensorArrays each now get a unique name at runtime, per step.  This means
  that they can be used in nested functional ops (e.g. tf.scan(tf.scan(...)))

Cherry-picking stability and doc fixes for r0.9

This prevents the TensorSliceWriter from attempting to serialize
variables that are larger than 2GB. It prevents potential memory
corruption and segmentation faults.

Fixes #2447.
Change: 124921899

Fixes #2326.

1. Re-disable fail-fast for the GrpcWorkerService.

This was broken in the change to a newer version of gRPC. Session
initialization and recovery relies on worker calls blocking until a
response is received.

2. Move the serialization specialization to the *_impl.h files, so that
   they are picked up when sending responses.

3. Raise an error when the ByteSize of a message to be serialized is
   negative.
Change: 124302956

This fixes a potential race condition and segfault, where the response
buffer could be deallocated with an RPC in flight. This would happen
if a step was cancelled before its master blocked on the RunGraph RPCs.

This will let us change some other kernels to use TF_CALL*, for cases where
no existing subset of types is what the kernel wants. This can help size on
IOS.
