Eric Snow 6b4be195cd bpo-22257: Small changes for PEP 432. (#1728)
PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.

T. Wouters a00c3fd12d bpo-29941: Assert fixes (#886)
Make a non-Py_DEBUG, asserts-enabled build of CPython possible. This means
making sure helper functions are defined when NDEBUG is not defined, not
just when Py_DEBUG is defined.

Also fix a division-by-zero in obmalloc.c that went unnoticed because in Py_DEBUG mode, elsize is never zero.

Serhiy Storchaka aefa7ebf0f bpo-6532: Make the thread id an unsigned integer. (#781)
* bpo-6532: Make the thread id an unsigned integer.

From C API side the type of results of PyThread_start_new_thread() and
PyThread_get_thread_ident(), the id parameter of
PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState
changed from "long" to "unsigned long".

* Restore a check in thread_get_ident().

* Add _PyObject_HasFastCall()

  arguments if the callable supports the FASTCALL calling convention
  for positional arguments.
* Fix also a performance regression in partial_call() if the callable
  doesn't support FASTCALL.

INADA Naoki aa289a59ff bpo-29548: Recommend PyObject_Call APIs over PyEval_Call APIs. (GH-75)
PyEval_Call* APIs are not documented and they doesn't respect PY_SSIZE_T_CLEAN.
So add comment block which recommends PyObject_Call* APIs to ceval.h.

This commit also changes PyEval_CallMethod and PyEval_CallFunction
implementation same to PyObject_CallMethod and PyObject_CallFunction
to reduce future maintenance cost.  Optimization to avoid temporary
tuple are copied too.

PyEval_CallFunction(callable, "i", (int)i) now calls callable(i) instead of
raising TypeError.  But accepting this edge case is backward compatible.

Victor Stinner 516b98161a Optimize slots: avoid temporary PyMethodObject
Issue #29507: Optimize slots calling Python methods. For Python methods, get
the unbound Python function and prepend arguments with self, rather than
calling the descriptor which creates a temporary PyMethodObject.

Add a new _PyObject_FastCall_Prepend() function used to call the unbound Python
method with self. It avoids the creation of a temporary tuple to pass
positional arguments.

Avoiding temporary PyMethodObject and avoiding temporary tuple makes Python
slots up to 1.46x faster. Microbenchmark on a __getitem__() method implemented
in Python:

Median +- std dev: 121 ns +- 5 ns -> 82.8 ns +- 1.0 ns: 1.46x faster (-31%)

Larry Hastings 57720e5e37 Fix incorrect patchlevel information for 3.5.3+.
It got messed up when I merged my private 3.5.3 release
changes with new work happening in the 3.5 main branch.
(3.5 main branch was in "3.5.3rc1", my branch was "3.5.3+",
and Mercurial helpfully merged the two in a kind of nonsense way.)
