This is faster, conceptually simpler and avoids finicky issues with dtype
precision.

V2 Checkpoints are common, now the default from all TFX
pipelines.  Users of this tool, when filling the 'file_name' flag are
likely to submit an actual filename, rather than the required
prefix.  This error message should catch those cases where the user is
very likely to have meant the prefix.

CL/149672538 has made TensorHandles directly feedable for Session.run() calls. This eliminates the need to call TensorHandles.eval() to get the value of a Tensor and feed it back in during tfdbg NodeStepper's cont() (i.e., continue-to) calls.

This change improves the memory efficiency and performance of NodeStepper.cont() by eliminating unnecessary Tensor-numpy and numpy-Tensor copying.

In order to support end-to-end debugging and performance profiling tooling for
the TensorFlow::XLA toolchain, this change adds a DebugMetadata proto to the
HloInstruction class, and pipes it through the tf2xla stack.

Refactored the debugger plugin test to use a real server. Modified the plugin code itself appropriately.

This makes the test more real and more streamlined since we do not need to fake various objects any more. Furthermore, this refactoring sets the stage for testing endpoints that read directly from disk and bypass the events multiplexer (which we want to do in order to read health pills at individual steps).

This CL works around what appears to be a bug in how Bazel sandbox
works. If an sh_binary() is listed under tools in genrule(), then the
contents of the data attribute of that sh_binary() do not seem to be a
part of the sandbox file system.

This is motivated by, among other goals, the need to enhance memory efficiency during TFDBG's stepper operations. The stepper caches TensorHandles to already-continued-to tensors and use them as feeds if later continue-to actions depend on the tensors as transitive inputs. However, previously the TensorHandles had to be converted to Numpy arrays by calling eval() and the Numpy arrays were then fed back to next Session.run() calls. This mode of operation involved at least two unnecessary tensor-numpy and numpy-tensor copying.

This CL makes it possible to use the ResourceHandle representations TensorHandles directly as feed values, eliminating the need for the aforementioned copying.

To this end, the following changes are made
1) the underlying representations of TensorHandles are changed from string to ResourceHandle. A custom numpy struct type is created to allow ResourceHandle of the TensorHandle subtype to be fed during Session.run() calls.
2) added GetSessionHandleOpV2, which deprecates GetSessionHandleOp. The V2 op outputs a DT_RESOURCE Tensor, instead of a string Tensor in the deprecated version.

Makes the head/multi-head API public and updates selected users while leaving other users using aliases.
This is CL#1 of a series of CLs to make head/multi-head API public and migrate all users. This CL,
+ Makes the Head interface and factory functions public.
+ Updates all tf-learn internal and SIR usage.
+ Leaves aliases for the legacy private names which will be removed with all existing usages in next CLs.
+ Also, updates documentation.
