Remove a legacy comment
* Refine TorchProxy
1. Make TorchProxy a formal singleton class.
2. Remove unused Scope class.
3. Simplify the call to Forward and Backward. The two functions now
automatically acquire and release GIL state, so user doesn't need
any GIL-related calls.
* Format
* Add lock to avoid racing condition when registering Python objs
* Fix Python call param ref issues && Add RefcountTracker for debug build && Clean up
* clean up print
* Resolve part of comments && clean up
* Fix a potential bug
* track pyobject consistently
* move kernels to cpu provider as base class
* Refactor - 1. Extract PythonOpBase/PythonOpGradBase 2. Implement CPU kernels 3. Test coverage for CPU kernels
* Refine register code
* Add a missing macro
* Release python call result objects with PythonObjectPtr && Add UnRegisterContext && Track PyObject for Debugging && Clena up
* Fix random segfault issue - relasing a wrong ctx pointer for inplace cases
* put ref count in debug macro
* Move GIL out
* Refine tests
* Fix memory leak issue && forward output lifecycle issue:
1. Unregister the OrtValue PythonObject. Currently, the OrtValue shared same buffer with PythonOp/PythonOpGrad's output. So after those kernels outputs are released, the "leaked" OrtValue caused the shared buffer cannot be released.
2. According PyTorch forward+backward execution. The forward outputs (e.g. torch tensors) maintains the context/saved variables/dirty inputs, etc, which are used for backward execution, so its life should be after the backward runs. This change added such a depencencies between PythonOpGrad on PythonOp.
* Move dlpack->ortvalue into C++ to avoid temp object registration
* Fix the over released Py_False/Py_True && refine tests
* Clean up unused functions
* Always assume the first forward output is context so we don't need to test unused cases.
* Fix a memory leak
* move-copy unique_ptr & avoid C-style casting
* Use inplace attribute to determine if input tensors are copied
* Move DlpackCapsuleDestructor's to a common place
* Thread-safe TorchProxy
* Use OrtValue instead of OrtValue*
* Only keep checks for Debug build
* Wrap some long line per comment
* onnx_export_type --> kwargs
* Use requires_grads to create PythonOpGrad's inputs
* add missing files during master merge
* Fix build issue after merge
* Address two comments.
1. Internalize DlpackCapsuleDestructor
2. Change "(" to "]" for describing closed interval.
* Address some comments.
1. "override" -> "overwrite" to avoid using reserved keyword.
2. Call DLPack's helper to create OrtValue for avoiding repeated code.
* Address comments.
1. Pass std::mutex to registeration helpers so their callers don't
have to lock the mutex expclicitly.
2. Rename "func_context_pool_mutex_" to "mutex_". This mutex is the global mutex for OrtTorchFunctionPool.
* Add bridging code to make cuda kernels work with merged master
* put debue macro check within RefCountTracker && use default logger for debug info && remove useless ortvalue_ptr interface && typos && revert unncessary blank line changes

PYTHON_LIBRARY_PATH python3.7m
* fix build error due to python lib not found
* Fixes
1. Release PyObject's
2. Not useing deepcopy because we assume autograd.Function's
non-tensor inputs are static (constants) so there should
be no side effect after calling any autograd.Function
multiple times.
* Revert dtoc for decreasing refcnt
