Go: Keep errors in Go.
Helps with #9931
- graph.go: Return a nil Operation if the operation creation failed.
This ensures that accidental usage of the nil operation results in
a panic/stacktrace purely in Go (nil pointer dereference) instead
of a SIGSEGV in the underlying C API.
- operation.go: Attempt to help in the developer find the root cause
of the nil pointer dereference with a chattier panic message.

Go: Output.Shape now returns a Shape object.
Output.Shape may be only partially known, hence the recently introduced Shape
type is a more appropriate return value.

go: Add Operation.OutputListSize
This will be needed for generating the function wrappers for ops that produce a
list of tensors as output.

go: Introduce Graph.AddOperation to add operations to the Graph.
Export an API to add operations to the graph.
I also intend to use this API in a code generator that will generate
Go sources files containing functions for each OpDef (and all
this generated code will be in a separate package).
While at it, also changed some tests to use the "sub-tests"
feature in Go 1.7 (https://blog.golang.org/subtests)
Another step in the journey of #10

go: Add an example.
Add an example (that will appear in Go doc) for a real use of the Go TensorFlow
APIs - using a pre-defined image recognition model for inference.
While at it a couple of minor tweaks:
- NewSession now accepts 'nil' for options as the documentation says it does
- Convenience accessors for the Outputs of an Operation
- Ability to extract (possibly partial) shapes from an Output

go: Prevent a Graph from being GCed while an Operation is alive.
And also add trivial accessors for Name() and Type() to the Operation type.
The lifetime of TF_Operation* objects is tied to the lifetime of the TF_Graph*
that they come from in the C API. Prior to this commit, it was possible for the
Go Graph object to be garbage collected even while the Operation object is
still alive.
The added test demonstrates this problem and fails with the following
if the Operation type doesn't hold on to a reference to the Graph:

Initial version of the Go API. The API is subject to change.
Remaining work to do:
- Generated ops.
- Generated protocol buffers.
- A few calls requiring protocol buffers aren't in this change.
