py-cython: updated to 0.29.18

0.29.18

Bugs fixed
* Exception position reporting could run into race conditions on threaded code.
  It now uses function-local variables again.
* Error handling early in the module init code could lead to a crash.
* Error handling in ``cython.array`` creation was improved to avoid calling
  C-API functions with an error held.
* A memory corruption was fixed when garbage collection was triggered during calls
  to ``PyType_Ready()`` of extension type subclasses.
* Memory view slicing generated unused error handling code which could negatively
  impact the C compiler optimisations for parallel OpenMP code etc.  Also, it is
  now helped by static branch hints.
* Cython's built-in OpenMP functions were not translated inside of call arguments.
* Complex buffer item types of structs of arrays could fail to validate.
* Decorators were not allowed on nested `async def` functions.
* C-tuples could use invalid C struct casting.
* Optimised ``%d`` string formatting into f-strings failed on float values.
* Optimised aligned string formatting (``%05s``, ``%-5s``) failed.
* When importing the old Cython ``build_ext`` integration with distutils, the
  additional command line arguments leaked into the regular command.
* When using the ``CYTHON_NO_PYINIT_EXPORT`` option in C++, the module init function
  was not declared as ``extern "C"``.
* Three missing timedelta access macros were added in ``cpython.datetime``.

py-cython: updated to 0.29.17

0.29.17:
Features added
std::move() is now available from libcpp.utility. Patch by Omer Ozarslan.
The @cython.binding decorator is available in Python code.

Bugs fixed
Creating an empty unicode slice with large bounds could crash. Patch by Sam Sneddon.
Decoding an empty bytes/char* slice with large bounds could crash. Patch by Sam \ 
Sneddon.
Re-importing a Cython extension no longer raises the error \ 
"__reduce_cython__ not found".
Unused C-tuples could generate incorrect code in 0.29.16. Patch by Kirk Meyer.
Creating a fused function attached it to the garbage collector before it was \ 
fully initialised, thus risking crashes in rare failure cases. Original patch by \ 
achernomorov.
Temporary buffer indexing variables were not released and could show up in C \ 
compiler warnings, e.g. in generators. Patch by David Woods.
The compilation cache in cython.inline("…") failed to take the \ 
language level into account. Patch by will-ca.
The deprecated PyUnicode_GET_SIZE() function is no longer used in Py3.

  deprecated ``build_ext`` command.

Other changes
* The ``PyMemoryView_*()`` C-API is available in ``cpython.memoryview``.

py-cython: updated to 0.29.12

0.29.12:
Bugs fixed
* Fix compile error in CPython 3.8b2 regarding the PyCode_New() signature.
* Fix a C compiler warning about a missing int downcast.
* Fix reported error positions of undefined builtins and constants.
* A 32 bit issue in the Pythran support was resolved.

Log message:
py-cython: updated to 0.29.11

0.29.11:

Bugs fixed

* Fix compile error in CPython 3.8b2.

* Invalid C code generated for lambda functions in cdef methods.

* Support slice handling in newer Pythran versions.

* A reference leak in power-of-2 calculation was fixed.

* The search order for include files was changed. Previously it was
  include_directories, Cython/Includes, sys.path. Now it is
  include_directories, sys.path, Cython/Includes. This was done to
  allow third-party *.pxd files to override the ones in Cython.
  Original patch by Matti Picus.

* Setting language_level=2 in a file did not work if language_level=3
  was enabled globally before.
