Looking at http://ci.tensorflow.org/job/tf-master-win-bzl/303/,

Passing config to MonitoredSession when using Estimator Class

Change: 144859450

This patch:
- Updates // comments to ///. I manually reverted some comments that shouldn't be docs (e.g. TODOs), but may have missed some.
- Indents code blocks so they get formatted as such in the docs.
- Removes /* */ comments from example code since it messes up Doxygen.
- Puts a space between {{ and }} since it messes up devsite.
- Adds some // START_SKIP_DOXYGEN and // END_SKIP_DOXYGEN comments for functions that aren't part of the public API (incomplete)

This will likely require further small fixups, but this gets something to be generated.

While this technically changes the API. This was in the TensorFlow 1.0 NumPy
design, so this is a bug fix to that plan, rather than a new API change.
Change: 144898546

Change weight broadcasting for losses.sparse_softmax_cross_entropy to be the same as sparse_softmax_cross_entropy_with_logits. This means allowing greater than rank 2 inputs.
Also, fix some pydoc.

Rename `weights` in `Dense` layer to `kernel`, and add base layer aliases for `(non_)trainable_weights`.
Change: 144752883

Change: 144737436
