bpo-29695: Fixed tests after removing keyword args support in some basic type constructors. (GH-520)

int(), bool(), float(), list() and tuple().  Specify the value as a
positional argument instead.

The docs for `heapq.merge` are a little misleading. Iterables passed
into heapq.merge with the reversed flag enabled must be sorted from
largest to smallest to achieve the desired sorting effect, but the
previous paragraph states that they should be sorted from smallest
to largest.

instanciated -> instantiated

Github doesn't support it (ref. isaacs/github#487).  So it can't ease
conflict on Github.

Additionally, it can make trouble when cherry-pick. (ref. GH-212)

* bpo-28087: Skip test_asyncore and test_eintr poll failures on macOS

Skip some tests of select.poll when running on macOS due to unresolved
issues with the underlying system poll function on some macOS versions.

* bpo-27593: Updates Windows build to use information from git

sys.version and the platform module python_build(),
python_branch(), and python_revision() functions now use
git information rather than hg when building from a repo.

Based on original patches by Brett Cannon and Steve Dower.

Change False into false, and True into true.

 #ifdef HAVE_DECLSPEC_DLL / #endif mismatch

Previously we configured the mention-bot to only mention people who are members of the Python organization. However, this doesn't currently work
if members don't have their membership public. Instead we will configure mention-bot to poke anyone, even non-members.
