Configure THREAD_LOCKS_PREALLOCATED in MemoryView.pyx via Tempita code generation rather than a DEF statement (as we ask users to do as well). See https://github.com/cython/cython/issues/4310

The current implementation of iterators had the following bugs: - it was possible to assign `const_iterator` to `iterator` - it was not possible to assign `iterator` to `const_iterator` - operator* did not always return `value_type` e.g. for `const_iterator` this often returned `T&` instead of `const value_type&` - increment operators always returned `iterators`. This caused e.g. `const_iterator + 1` to result in a `iterator` instead of a `const_iterator` - comparision operators could not be used to compare `iterators` and `const_iterators` (`const_iterator == iterator`)

Lists of "negative" length are also empty, and that's the case we special-case later in an inline function, so use the same condition for consistency and easy C compiler optimisation. See https://github.com/cython/cython/pull/4734

Some code I have uses lxml. When I compile and run lxml with LLVM-12's undefined behaviour sanitizer, I see this: ``` lxml/4.6.3/cython_parts=etree.c/etree.c:191228:65: runtime error: applying zero offset to null pointer #0 0x7faedc799e7c in __Pyx_PyList_GetSlice lxml/4.6.3/cython_parts=etree.c/etree.c:191228 #1 0x7faedc6b3723 in __pyx_f_4lxml_5etree_9_ErrorLog_copy lxml/4.6.3/cython_parts=etree.c/etree.c:38092 #2 0x7faedc77636e in __pyx_f_4lxml_5etree___copyGlobalErrorLog lxml/4.6.3/cython_parts=etree.c/etree.c:40203 #3 0x7faedc775a5c in __pyx_pf_4lxml_5etree_9LxmlError___init__ lxml/4.6.3/cython_parts=etree.c/etree.c:21080 #4 0x7faedc774dff in __pyx_pw_4lxml_5etree_9LxmlError_1__init__ lxml/4.6.3/cython_parts=etree.c/etree.c:21019 ``` which implies that Cython's generating undefined behaviour. Making an early exit from the modified function (essentially by hoisting an early exit from one level lower in the stack) avoids this.

CI: Use same capital case package name spelling as other dependencies do. Seems like pip can get confused about this (maybe just temporarily).

This is used by some optimisations for builtins that call C-API functions directly but need to convert None arguments to NULL or special integer values in order to mimic the original Python interface. Also add and backport the CPython macros for None checks (and True/False, while we're at it): https://docs.python.org/3/c-api/structures.html#c.Py_Is Closes https://github.com/cython/cython/issues/4737 See https://github.com/cython/cython/issues/4706

Use "\x20" instead of a plain space at the end of a doctest output line to make it easier to edit. Some editors strip off trailing whitespace.

The condition should only evaluate to True when assigning __dict__, but it currently does for _, d, i, etc. as well as resulting in the following potential issues: * Non-member are being assigned to the object instead of raising. * The one-field rule can be bypassed. * Valid members that pass the condition are being assigned raw and are never cast to the specified type.

Disable "CYTHON_UPDATE_DESCRIPTOR_DOC" for Pyston. It was previously only enabled for CPython and should only have been enabled additionally for recent PyPy versions.

Stop using "PyBytesObject.ob_shash" in Py3.11, where it is deprecated. It was just an optimisation that isn't very important for byte strings any more. Closes https://github.com/cython/cython/issues/4721
