Improvements to function._FuncGraph.

a new method, func_graph_from_py_func().
These changes are in preparation for converting tf.cond to emit an If

Update SessionTest.testFeedShapeCompatibility to work with C API enabled.
This test got lost in the transition. Prior to enabling the C API,
some constant node whose values were used for shape inference would be
marked as unfeedable in tensor_util.constant_value
(https://github.com/tensorflow/tensorflow/blob/r1.8/tensorflow/python/framework/tensor_util.py#L810).
This shape inference path is no longer used with the C API enabled, so
the constant node is successfully fed, triggering a runtime shape error.
This is arguably a regression, but given that the Python code wouldn't
mark all nodes evaluated during shape inference as unfeedable, it
seems ok to relax the check a little more.

magnitude 13.
94238515. Note that this quantity is not representable as a single
precision float and is instead rounded to 13.9423847.
If softplus would overflow, it will be approximated as x.
If softplus would underflow, it will be approximated as exp(x).
Unfortunately, this can provide inaccurate results for negative floats close to
the threshold.
For example: consider x = -13.
9274826049805. softmax(x) is ~8.
94068849e-7;
rounded to the nearest single precision float, this is 8.940689e-7.
In this case, x is quite close to the underflow threshold but not close enough
to be approximated by exp(x) == 8.
94069273e-7.
Rather, it gets calculated using the canonical definition of softmax and comes
to 8.
34464686e-7.
This result comes out to be wrong by 1,048,568 ULPs.
Instead, we can compute it the way one would compute LogSumExp(x, 0):
max(x, 0) + log(exp(x - max(x, 0)) + exp(0 - max(x, 0)))
When x is positive, this is:
x + log(exp(0) + exp(-x))
When x is negative, this is:
log(exp(x) + exp(0))
When x is 0, this is:
log(exp(0) + exp(0))
exp(0) evaluates to 1 which gives us:
if x is positive, x + log(1 + exp(-x))
if x is negative, log(exp(x) + 1)
if x is zero, log(2)
These three cases can be combined like so:
max(x, 0) + log(exp(-abs(x)) + 1)
Further, we can increase the fidelity of the log calculation by using log1p:
max(x, 0) + log1p(exp(-abs(x)))
This computation naturally handles underflow and overflow while also providing
more numerically accurate results for a few small, positive, floating point
values.

Fix bug in `WorkerService::Logging()` handler.
Since transitioning to proto3, it was not possible to distinguish between the absence of
LoggingRequest::rpc_logging and it being set to false. This led to a bug that ignored
log-disabling messages in some implementations, which meant that logging was never
disabled. This fix adds explicit fields in LoggingRequest for enabling and disabling RPC
logging.
