* Update release notes for 1.0.0-alpha.

* Add numpy compatibility to release notes.

Setting losses_test to medium since it times out on Jenkins at times.

* worspace.bzl uses zlib permalink

zlib permalinks including the current version are always in http://zlib.net/fossils/zlib-*.*.*.tar.gz
links in http://zlib.net/zlib-*.*.*.tar.gz are removed when no longer current.

Should resolve #6594 if merged into r0.12 branch.

* Remove comment, moving to git commit description.

This CL includes wrapper classes for the protocol buffer messages
`tensorflow::RunStepRequest` and `tensorflow::RunGraphRequest`.

Previously the service arguments were always protocol buffer messages,
which can entail copying large tensor values into and out of the
request message. This change makes the backend code deal with abstract
`tensorflow::RunStepRequestWrapper` and
`tensorflow::RunGraphRequestWrapper` interfaces and adds three
concrete implementations of each interface:

* An mutable in-memory wrapper, which maintains the tensor data in
  `tensorflow::Tensor` objects, and provides the most efficient
  implementation when the client and master are in the same address
  space.

* A mutable protobuf wrapper, which has a similar implementation to
  today's client code.

* A const wrapper around a const protobuf, which has a similar
  implementation to today's server code.

This is another improvement for issue #6256.

Defer optimizer function run in linear classifier until apply gradient step. This keeps the worker to get correct global step through contrib_variables.get_global_step. This defer also enables the use of a customized learning rate in optimizer, e.g. exp decay learning rate in linear classifier. Otherwise it will cause "global_step is required" error when runs with replicas.

Removing comments for investigation of the root cause of test tolerance change. Turns out it is expected: originally a more strict tolerance was used incorrectly where it has been known to be too restrictive for other similar test cases when expanding the tests to cover the added projection operation.

This operator is initialized with a num_rows and batch_shape parameter.  An alternative would be a single shape parameter.  The reasons for this are:

1.  Compatibility with tf.eye and np.eye
2.  If "shape" was used, and ndims was not known statically, then operator.apply(x) and operator.solve(x) need to force a broadcast by adding an array of zeros.  This is unnecessarily inefficient.  Having an explicit "batch_shape=None" option allows (in the event that batch_shape is None) operator.apply(x) and operator.solve(x) to simply return x.

Previously it was assumed overrides would be statically on or off (either way the override itself could have been non-static). This cl allows for fully dynamic specification of batch_shape and/or event_shape override, ie, we no longer require that the decision to override shape be known during graph construction.
