bpo-43974: Move Py_BUILD_CORE_MODULE into module code (GH-29157)
setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every
module defines the macro before #include "Python.h" unless
Py_BUILD_CORE_BUILTIN is already defined.

Py_BUILD_CORE_BUILTIN is defined for every module that is built by
Modules/Setup.

The PR also simplifies Modules/Setup. Makefile and makesetup
already define Py_BUILD_CORE_BUILTIN and include Modules/internal
for us.

bpo-43413: Fix handling keyword arguments in subclasses of some buitin classes (GH-26456)
* Constructors of subclasses of some buitin classes (e.g. tuple, list,
  frozenset) no longer accept arbitrary keyword arguments.
* Subclass of set can now define a __new__() method with additional
  keyword parameters without overriding also __init__().

bpo-40137: Add pycore_moduleobject.h internal header (GH-25507)
Add pycore_moduleobject.h internal header file with static inline
functions to access module members:

* _PyModule_GetDict()
* _PyModule_GetDef()
* _PyModule_GetState()

These functions don't check at runtime if their argument has a valid
type and can be inlined even if Python is not built with LTO.

_PyType_GetModuleByDef() uses _PyModule_GetDef().

Replace PyModule_GetState() with _PyModule_GetState() in the
extension modules, considered as performance sensitive:

* _abc
* _functools
* _operator
* _pickle
* _queue
* _random
* _sre
* _struct
* _thread
* _winapi
* array
* posix

The following extensions are now built with the Py_BUILD_CORE_MODULE
macro defined, to be able to use the internal pycore_moduleobject.h
header: _abc, array, _operator, _queue, _sre, _struct.

bpo-40286: Remove C implementation of Random.randbytes() (GH-19797)
Remove _random.Random.randbytes(): the C implementation of
randbytes(). Implement the method in Python to ease subclassing:
randbytes() now directly reuses getrandbits().

* Replace PY_INT64_T with int64_t
* Replace PY_UINT32_T with uint32_t
* Replace PY_UINT64_T with uint64_t

sha3module.c no longer checks if PY_UINT64_T is defined since it's
always defined and uint64_t is always available on platforms
supported by Python.

bpo-40286: Add randbytes() method to random.Random (GH-19527)
Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.

Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().

Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.

The _random module is now built with Py_BUILD_CORE_MODULE defined.

Dino Viehland 04f0bbfbed bpo-38075: Port _randommodule.c to PEP-384 (GH-15798)
- Migrate `Random_Type` to `PyType_FromSpec`
- To simulate an old use of `PyLong_Type.tp_as_number->nb_absolute`, I added
  code to the module init function to stash `int.__abs__` for later
  use. Ideally we'd use `PyType_GetSlot()` instead, but it doesn't currently
  work for static types in CPython, and implementing it just for this case
  doesn't seem worth it.
- Do exact check for long and dispatch to PyNumber_Absolute, use vector call when not exact.

METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.
