* Can now specify which variables can be fed/fetched. * Bugfix when signature name contains slashes or starts with integers. * Prune input config entries from tf2xla config when graph freeze removes unused input feed. * Fixed a bug where third_party/tensorflow/ isn't properly renamed to tensorflow/ in opensource HOST build (identified during the new genrule test). Solution: bring back the hardcoded #include in codegen.cc; it's always correct. NOTE: The bugfix to the #include line in the compiler/ codebase is a partial rollback of the initial tfcompile + saved_model_cli CL which moved from the hard-coded include path to a parameterized value. It turns out we don't need the complexity of this approach and it's incorrect in the host opensource build. TESTED: Includes a bonafide genrule test which runs saved_model_cli to generate the header and object files, and includes them in a c++ unit test and ensures that they compile and the resulting object runs correctly.
