bpo-35134: Don't define types twice in header files (GH-10754)
Fix the following clang warning:

    Include/cpython/pystate.h:217:3: warning: redefinition of
    typedef 'PyThreadState' is a C11 feature [-Wtypedef-redefinition]

bpo-35134: Create Include/cpython/object.h (GH-10679)
* Move object.h code surrounded by "#ifndef Py_LIMITED_API"
  to a new Include/cpython/object.h header file.
* "typedef struct _typeobject PyTypeObject;" is now always defined
  in object.h, but if Py_LIMITED_API is not defined,
  Include/cpython/object.h also defines the structure.
* Complete the printfunc comment to mention Py_LIMITED_API define.

bpo-35059: Add _PyObject_CAST() macro (GH-10645)

to PyObject* and PyVarObject* properly.

bpo-35059: Convert _PyObject_GC_TRACK() to inline function (GH-10643)
* Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG()
  macros.
* PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(),
  instead of Py_FatalError(), if the object is already tracked, to
  dump more information on error.
* _PyObject_GC_TRACK() no longer checks if the object is already
  tracked at runtime, use an assertion instead for best performances;
  PyObject_GC_Track() still checks at runtime.
* pycore_object.h now includes pycore_pystate.h.
* Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to
  inline functions.

bpo-35059: Convert _Py_Dealloc() to static inline function (GH-10223)
Convert _Py_Dealloc() macro into a static inline function. Moreover,
it is now also defined as a static inline function if Py_TRACE_REFS
is defined.

bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ (GH-10152)
Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0"
makes "make smelly" fail as some symbols were being exported without the "Py_" or
"_Py" prefixes.

bpo-35053: Define _PyTraceMalloc_NewReference in object.h (GH-10107)
_PyTraceMalloc_NewReference() is now called by _Py_NewReference(), so
move its definition to object.h. Moreover, define it even if
Py_LIMITED_API is defined, since _Py_NewReference() is also exposed
even if Py_LIMITED_API is defined.

bpo-9263: Dump Python object on GC assertion failure (GH-10062)
Changes:

* Add _PyObject_AssertFailed() function.
* Add _PyObject_ASSERT() and _PyObject_ASSERT_WITH_MSG() macros.
* gc_decref(): replace assert() with _PyObject_ASSERT_WITH_MSG() to
  dump the faulty object if the assertion fails.

_PyObject_AssertFailed() calls:

* _PyMem_DumpTraceback(): try to log the traceback where the object
  memory has been allocated if tracemalloc is enabled.
* _PyObject_Dump(): log repr(obj).
* Py_FatalError(): log the current Python traceback.

_PyObject_AssertFailed() uses _PyObject_IsFreed() heuristic to check
if the object memory has been freed by a debug hook on Python memory
allocators.

Initial patch written by David Malcolm.

bpo-35059: Add Py_STATIC_INLINE() macro (GH-10093)
* Add Py_STATIC_INLINE() macro to declare a "static inline" function.
  If the compiler supports it, try to always inline the function even if no
  optimization level was specified.
* Modify pydtrace.h to use Py_STATIC_INLINE() when WITH_DTRACE is
  not defined.
* Add an unit test on Py_DECREF() to make sure that
  _Py_NegativeRefcount() reports the correct filename.

bpo-35053: Add Include/tracemalloc.h (GH-10091)
* Modify object.h to ensure that pymem.h is included,
  to get _Py_tracemalloc_config variable.
* Move _PyTraceMalloc_XXX() functions to tracemalloc.h,
  they need PyObject type. Break circular dependency between pymem.h
  and object.h.

bpo-35053: Enhance tracemalloc to trace free lists (GH-10063)
tracemalloc now tries to update the traceback when an object is
reused from a "free list" (optimization for faster object creation,
used by the builtin list type for example).

Changes:

* Add _PyTraceMalloc_NewReference() function which tries to update
  the Python traceback of a Python object.
* _Py_NewReference() now calls _PyTraceMalloc_NewReference().
* Add an unit test.

bpo-9263: _PyObject_Dump() detects freed memory (GH-10061)
_PyObject_Dump() now uses an heuristic to check if the object memory
has been freed: log "<freed object>" in that case.

The heuristic rely on the debug hooks on Python memory allocators
which fills the memory with DEADBYTE (0xDB) when memory is
deallocated. Use PYTHONMALLOC=debug to always enable these debug
hooks.

bpo-32544: Speed up hasattr() and getattr() (GH-5173)
AttributeError was raised always when attribute is not found.
This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`.
It makes hasattr() and getattr() about 4x faster when attribute is not found.

Victor Stinner 742da040db Implement compact dict
Issue #27350: `dict` implementation is changed like PyPy. It is more compact

_PyDict_Dummy() function has been removed.

Disable test_gdb: python-gdb.py is not updated yet to the new structure of
compact dictionaries (issue #28023).
