Minor C API documentation improvements. (GH-17696)
The added parentheses around the PyIter_Next assignment suppress the following warning which gcc throws without: ``` warning: using the result of an assignment as a condition without parentheses [-Wparentheses] ``` The other change is a typo fix

bpo-39028: Performance enhancement in keyword extraction (GH-17576)
All keywords should first be checked for pointer identity. Only after that failed for all keywords (unlikely) should unicode equality be used. The original code would call unicode equality on any non-matching keyword argument. Meaning calling it often e.g. when a function has many kwargs but only the last one is provided.

bpo-38546: multiprocessing tests stop the resource tracker (GH-17641)
Multiprocessing and concurrent.futures tests now stop the resource tracker process when tests complete. Add ResourceTracker._stop() method to multiprocessing.resource_tracker. Add _cleanup_tests() helper function to multiprocessing.util: share code between multiprocessing and concurrent.futures tests.

bpo-38858: Small integer per interpreter (GH-17315)
Each Python subinterpreter now has its own "small integer singletons": numbers in [-5; 257] range. It is no longer possible to change the number of small integers at build time by overriding NSMALLNEGINTS and NSMALLPOSINTS macros: macros should now be modified manually in pycore_pystate.h header file. For now, continue to share _PyLong_Zero and _PyLong_One singletons between all subinterpreters.

bpo-38811: Check for presence of os.link method in pathlib (GH-17225)
Commit 6b5b013 ("bpo-26978: Implement pathlib.Path.link_to (Using os.link) (GH-12990)") introduced a new link_to method in pathlib. However, this makes pathlib crash when the 'os' module is missing a 'link' method. Fix this by checking for the presence of the 'link' method on pathlib module import, and if it's not present, turn it into a runtime error like those emitted when there is no lchmod() or symlink().
