changes:
-Breaks bc: Tensor::type() now returns DeprecatedTypeProperties& rather than Type&.
-Added DeprecatedTypeProperties, it serves as a temporary replacement for Type as the return value of Tensor::type(). This contributes to making Type just for dispatch purposes so that we can make it dtype agnostic.
-Tensor::dispatch_type() now returns Type& like Tensor::type() used to do.
-Changed callsites of Tensor::type() appropriately.

Summary:
This PR adds the final set of clang-tidy checks we should add for our codebase: a last set of performance-related checks. Most fixes here are around changing `auto` to `const auto&` in a few places where unnecessary copies were made, and adding `reserve()` calls before loops doing repeated `push_back()`. Also a few cases of calling `std::string::find` with a single-character string literal instead of a single char, which uses a less efficient string search algorithm meant for searching larger substrings.

Summary:
Replaces the `DefaultTensorOptions` with just a global default dtype that you can set and get like in Python.
Also, calls `set_default_dtype` in the implementation of `torch.set_default_dtype`. Right now these two default values are separate but will always be the same. Should we just bind `set_default_dtype` into Python? I think that might be good to do in a separate PR though.

Summary:
Currently the C++ API and C++ extensions are effectively two different, entirely orthogonal code paths. This PR unifies the C++ API with the C++ extension API by adding an element of Python binding support to the C++ API. This means the `torch/torch.h` included by C++ extensions, which currently routes to `torch/csrc/torch.h`, can now be rerouted to `torch/csrc/api/include/torch/torch.h` -- i.e. the main C++ API header. This header then includes Python binding support conditioned on a define (`TORCH_WITH_PYTHON_BINDINGS`), *which is only passed when building a C++ extension*.
Currently stacked on top of https://github.com/pytorch/pytorch/pull/11498
Why is this useful?
1. One less codepath. In particular, there has been trouble again and again due to the two `torch/torch.h` header files and ambiguity when both ended up in the include path. This is now fixed.
2. I have found that it is quite common to want to bind a C++ API module back into Python. This could be for simple experimentation, or to have your training loop in Python but your models in C++. This PR makes this easier by adding pybind11 support to the C++ API.
3. The C++ extension API simply becomes richer by gaining access to the C++ API headers.

- getVariableTypeFromBaseType: given a base Type (non-Variable type)
compute the Variable Type which corresponds to it.
- getVariableType: like at::getType, but return the Variable type
rather than the plain type.
This rename makes it clearer at the use-site what things are what,
and will make a subsequent rename of at::getType easier.

- Removed Backend constructor from Device, and fixed all
use-sites to use DeviceType::CPU instead of kCPU, or
use a new function backendToDeviceType to perform
the conversion.
- New method device_type() on Type; it gives you the
underlying device type, e.g., CPU for SparseCPU.
- We add backward compatibility for kCPU/kCUDA uses,
by introducing a new special type which is implicitly
convertible to both DeviceType and Backend. As long as
you don't define a function that's overloaded on both
DeviceType and Backend (but not on BackendOrDeviceType),
the implicit conversions will ensure that uses
of at::Device(at::kCPU) keep working. We fixed use-sites in
the library, but did NOT fix sites in the test code, so that
we can exercise this BC code.

I got some tensor->variable conversion exceptions from `torch/csrc/autograd/variable.h`, which used the `TORCH_ASSERTM` macros instead of `AT_CHECK`, so they didn't have backtraces. This was such a substantial loss for debugability that I decided to update the whole codebase to use the backtrace-enabled ATen macros instead of `TORCH_ASSERT` and `JIT_ASSERT`, the latter having been an alias of the former.

Previously, ATen could be built with either CPU-only support, or
CPU/CUDA support, but only via a compile-time flag, requiring
two separate builds. This means that if you have a program which
indirectly uses a CPU-only build of ATen, and a CPU/CUDA-build of
ATen, you're gonna have a bad time. And you might want a CPU-only
build of ATen, because it is 15M (versus the 300M of a CUDA build).
This commit splits libATen.so into two libraries, CPU/CUDA, so
that it's not necessary to do a full rebuild to get CPU-only
support; instead, if you link against libATen_cpu.so only, you
are CPU-only; if you additionally link/dlopen libATen_cuda.so,
this enables CUDA support. This brings ATen's dynamic library
structure more similar to Caffe2's. libATen.so is no more
(this is BC BREAKING)
The general principle for how this works is that we introduce
a *hooks* interface, which introduces a dynamic dispatch indirection
between a call site and implementation site of CUDA functionality,
mediated by a static initialization registry. This means that we can continue
to, for example, lazily initialize CUDA from Context (a core, CPU class) without
having a direct dependency on the CUDA bits. Instead, we look up
in the registry if, e.g., CUDA hooks have been loaded (this loading
process happens at static initialization time), and if they
have been we dynamic dispatch to this class. We similarly use
the hooks interface to handle Variable registration.
We introduce a new invariant: if the backend of a type has not
been initialized (e.g., it's library has not been dlopened; for
CUDA, this also includes CUDA initialization), then the Type
pointers in the context registry are NULL. If you access the
registry directly you must maintain this invariant.
There are a few potholes along the way. I document them here:
- Previously, PyTorch maintained a separate registry for variable
types, because no provision for them was made in the Context's
type_registry. Now that we have the hooks mechanism, we can easily
have PyTorch register variables in the main registry. The code
has been refactored accordingly.
- There is a subtle ordering issue between Variable and CUDA.
We permit libATen_cuda.so and PyTorch to be loaded in either
order (in practice, CUDA is always loaded "after" PyTorch, because
it is lazily initialized.) This means that, when CUDA types are
loaded, we must subsequently also initialize their Variable equivalents.
Appropriate hooks were added to VariableHooks to make this possible;
similarly, getVariableHooks() is not referentially transparent, and
will change behavior after Variables are loaded. (This is different
to CUDAHooks, which is "burned in" after you try to initialize CUDA.)
- The cmake is adjusted to separate dependencies into either CPU
or CUDA dependencies. The generator scripts are adjusted to either
generate a file as a CUDA (cuda_file_manager) or CPU file (file_manager).
- I changed all native functions which were CUDA-only (the cudnn functions)
to have dispatches for CUDA only (making it permissible to not specify
all dispatch options.) This uncovered a bug in how we were handling
native functions which dispatch on a Type argument; I introduced a new
self_ty keyword to handle this case. I'm not 100% happy about it
but it fixed my problem.
This also exposed the fact that set_history incompletely handles
heterogenous return tuples combining Tensor and TensorList. I
swapped this codegen to use flatten() (at the possible cost of
a slight perf regression, since we're allocating another vector now
in this code path).
- thc_state is no longer a public member of Context; use getTHCState() instead
- This PR comes with Registry from Caffe2, for handling static initialization.
I needed to make a bunch of fixes to Registry to make it more portable
- No more ##__VA_ARGS__ token pasting; instead, it is mandatory to pass at
least one argument to the var-args. CUDAHooks and VariableHooks pass a nullary
struct CUDAHooksArgs/VariableHooksArgs to solve the problem. We must get rid of
token pasting because it does not work with MSVC.
- It seems MSVC is not willing to generate code for constructors of template
classes at use sites which cross DLL boundaries. So we explicitly instantiate
the class to get around the problem. This involved tweaks to the boilerplate
generating macros, and also required us to shuffle around namespaces a bit,
because you can't specialize a template unless you are in the same namespace as
the template.
- Insertion of AT_API to appropriate places where the registry must be exported
- We have a general problem which is that on recent Ubuntu distributions,
--as-needed is enabled for shared libraries, which is (cc @apaszke who was
worrying about this in #7160 see also #7160 (comment)). For now, I've hacked
this up in the PR to pass -Wl,--no-as-needed to all of the spots necessary to
make CI work, but a more sustainable solution is to attempt to dlopen
libATen_cuda.so when CUDA functionality is requested.
- The JIT tests somehow manage to try to touch CUDA without loading libATen_cuda.so. So
we pass -Wl,--no-as-needed when linking libATen_cuda.so to _C.so
- There is a very subtle linking issue with lapack, which is solved by making sure libATen_cuda.so links against LAPACK. There's a comment in aten/src/ATen/CMakeLists.txt about htis as well as a follow up bug at #7353
- autogradpp used AT_CUDA_ENABLED directly. We've expunged these uses and added
a few more things to CUDAHooks (getNumGPUs)
- Added manualSeedAll to Generator so that we can invoke it polymorphically (it
only does something different for CUDAGenerator)
- There's a new cuda/CUDAConfig.h header for CUDA-only ifdef macros (AT_CUDNN_ENABLED, most prominently)
- CUDAHooks/VariableHooks structs live in at namespace because Registry's
namespace support is not good enough to handle it otherwise (see Registry
changes above)
- There's some modest moving around of native functions in ReduceOps and
UnaryOps to get the CUDA-only function implementations into separate files, so
they are only compiled into libATen_cuda.so. sspaddmm needed a separate CUDA
function due to object linkage boundaries.
- Some direct uses of native functions in CUDA code has to go away, since these
functions are not exported, so you have to go through the dispatcher
(at::native::empty_like to at::empty_like)
- Code in THC/THCS/THCUNN now properly use THC_API macro instead of TH_API
(which matters now that TH and THC are not in the same library)
- Added code debt in torch/_thnn/utils.py and other THNN parsing code to handle
both TH_API and THC_API
- TensorUtils.h is now properly exported with AT_API
- Dead uses of TH_EXPORTS and co expunged; we now use ATen_cpu_exports and
ATen_cuda_exports (new, in ATenCUDAGeneral.h) consistently
- Fix some incorrect type annotations on _cudnn_rnn_backward, where we didn't
declare a type as possibly undefined when we should have. We didn't catch this
previously because optional annotations are not tested on "pass-through" native
ATen ops (which don't have dispatch). Upstream issue at #7316
- There's a new cmake macro aten_compile_options for applying all of our
per-target compile time options. We use this on the cpu and cuda libraries.
- test/test_cpp_extensions.py can be run directly by invoking in Python,
assuming you've setup your PYTHONPATH setup correctly
- type_from_string does some new funny business to only query for all valid CUDA
types (which causes CUDA initialization) when we see "torch.cuda." in the
requested string

* Split set_default_tensor_type(dtype) into set_default_dtype(dtype).
* Fix flake8.
The difference between this one and set_default_tensor_type is that it only sets scalar type what determines the type + device of a tensor returned from a factory function with defaults is the default tensor type + the current device (if the default tensor type is cuda). This just changes the scalar type of the default tensor type.
We do eventually want to deprecate set_default_tensor_type; it is not clear how to do that in a sensible and backwards compatible way.
* Separate cuda-ness from dtype.
There are no longer torch.cuda.int64, etc; only torch.int64 that correspond to at::ScalarType.
At the python arg parser level, the corresponding ATen type is selected from the combination of (ScalarType, Layout, Device).
There is also currently unused code in here for support ScalarType in native_functions; this will be used for specifying aggregate types
on reduction functions.

* Add defaults to randint_like.
* Track is_cuda in py tensor types.
* Fix test_sparse.
* Fix multiprocessing.
* Fix rnn.

* Fix flake8.
This changes type(tensor) to return `torch.Tensor` instead of
`torch.autograd.Variable`.
This requires a few implementation changes:
- torch.Tensor is now a regular Python class instead of a
pseudo-factory like torch.FloatTensor/torch.DoubleTensor
- torch.autograd.Variable is just a shell with a __new__ function.
Since no instanes are constructed it doesn't have any methods.
- Adds torch.get_default_dtype() since torch.Tensor.dtype returns
<attribute 'dtype' of 'torch._C._TensorBase' objects>
* Introduce torch.layout and split layout from dtypes.
Tensors (and tensor types) now have a 'layout' attribute that returns either 'torch.strided' or 'torch.sparse_coo'.
Previously, dtypes were 1-to-1 with ATen types/PyTensorTypes; the impetus behind this decision was to make things easy in the common case
(i.e. specifying a type in a factory function). But this doesn't really follow for sparity, which isn't a common case.
It also doesn't properly represent the concept or a dtype, which in numpy are proper scalar types (i.e. roughly the type returned from indexing the
last dimension of an n-d array). But this should be the same whether or not the tensor is represented via strides, sparsity, etc.
This is accomplished by:
1) having the dtype of tensor return the (device-type, scalar-type) combination, i.e. torch.cuda.float32, so both
torch.cuda.FloatTensor and torch.cuda.sparse.FloatTensor have the same dtype
2) Adding a layout parameter to python functions, where the combination of (dtype, layout) maps to an ATen type that is used for dispatch.

This deletes most of the dead Tensor code paths, including the TensorMethods cwrap and generic/Tensor.cpp.
This also moves the THNN.cwrap/.cpp generation to generate_code which can use ninja if installed.
This replaces the torch.Tensor constructors with factories that produce
Variables. Similarly, functions on the torch module (e.g. torch.randn)
now return Variables.
To keep the PR to a reasonable size, I've left most of the unused tensor
code. Subsequent PRs will remove the dead code, clean-up calls to
torch.autograd.Variable, and rename Variable to Tensor everywhere.
There are some breaking changes because Variable and Tensors had
slightly different semantics. There's a list of those changes here:
