Bumps cython from 0.29.15 to 0.29.20.

Changelog

Sourced from cython's changelog.

0.29.20 (2020-06-10)

Bugs fixed

• Nested try-except statements with multiple return statements could crash due to incorrect deletion of the except as target variable. (Github issue #3666)
• The @classmethod decorator no longer rejects unknown input from other decorators. Patch by David Woods. (Github issue #3660)
• Fused types could leak into unrelated usages. Patch by David Woods. (Github issue #3642)
• Now uses Py_SET_SIZE() and Py_SET_REFCNT() in Py3.9+ to avoid low-level write access to these object fields. Patch by Victor Stinner. (Github issue #3639)
• The built-in abs() function could lead to undefined behaviour when used on the negative-most value of a signed C integer type. Patch by Serge Guelton. (Github issue #1911)
• Usages of sizeof() and typeid() on uninitialised variables no longer produce a warning. Patch by Celelibi. (Github issue #3575)
• The C++ typeid() function was allowed in C mode. Patch by Celelibi. (Github issue #3637)
• The error position reported for errors found in f-strings was misleading. (Github issue #3674)
• The new c_api_binop_methods directive was added for forward compatibility, but can only be set to True (the current default value). It can be disabled in Cython 3.0.

0.29.19 (2020-05-20)

Bugs fixed

• A typo in Windows specific code in 0.29.18 was fixed that broke "libc.math". (Github issue #3622)
• A platform specific test failure in 0.29.18 was fixed. Patch by smutch. (Github issue #3620)

0.29.18 (2020-05-18)

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. (Github issue #3603)
• 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. (Github issue #2987)
• Cython's built-in OpenMP functions were not translated inside of call arguments. Original patch by Celelibi and David Woods. (Github issue #3594)
• Complex buffer item types of structs of arrays could fail to validate. Patch by Leo and smutch. (Github issue #1407)
• Decorators were not allowed on nested async def functions. (Github issue #1462)
• C-tuples could use invalid C struct casting. Patch by MegaIng. (Github issue #3038)
• Optimised %d string formatting into f-strings failed on float values. (Github issue #3092)
• Optimised aligned string formatting (%05s, %-5s) failed. (Github issue #3476)
• When importing the old Cython build_ext integration with distutils, the additional command line arguments leaked into the regular command. Patch by Kamekameha. (Github issue #2209)
• When using the CYTHON_NO_PYINIT_EXPORT option in C++, the module init function was not declared as extern "C". (Github issue #3414)
• Three missing timedelta access macros were added in cpython.datetime.
• The signature of the NumPy C-API function PyArray_SearchSorted() was fixed. Patch by Brock Mendel. (Github issue #3606)
