Badges are small images which gives the status of the Travis CI and
the coverage percentage of Codecode. It helps to check the status of
the Travis CI and to get the link to Travis CI.

Currently, http://buildbot.python.org/all/buildslaves/ware-docs
buildbot is only run as post-commit. For example, bpo-29521 (PR#41)
introduced two warnings, unnotified by the Travis CI docs job.

Modify the docs job to run toosl/rstlint.py.

Fix also the two minor warnings which causes the buildbot slave to
fail.

Much of bpo-29521 was fixed in parallel with commit 
e7ffb99f .  This cleans up the rest.

Apply parallel change to Doc/make.bat to read

I don't have a Windows system on which to observe the warning,
but it should be necessary.

The warning:

.../workspace/cpython_github/Doc/faq/windows.rst:303: 
    WARNING: unknown option: -t

In the Windows FAQ, `How do I keep editors from inserting tabs 
into my Python source?`, contained a reference to a Python -t
option. In Python 2.x, this caused Python to issue warnings
about lines with mixed spaces and tabs, but as of Python 3.6
it does nothing. 
 
Per discussion at http://bugs.python.org/issue29387, take
their wording. Python [3] raises an IndentationError or 
TabError. Tabnanny is now a module.

Set name to "_curses.window" instead of "_curses.curses window" (with
a space!?).

EasyDialogs was removed in 3.x. fallback_getpass will always be the answer here.

* bpo-28929: Link the documentation to its source file on GitHub

Change the documentation's `Show Source` link on the left menu
to GitHub source file.

* change version to master

* Move all functions to call objects in a new Objects/call.c file.
* Rename fast_function() to _PyFunction_FastCallKeywords().
* Copy null_error() from Objects/abstract.c
* Inline type_error() in call.c to not have to copy it, it was only
  called once.
* Export _PyEval_EvalCodeWithName() since it is now called
  from call.c.

There were some grammatical errors in weakref.WeakValueDictionary
documentation.

It took me quite a bit to figure out what this was referring to,
since the given issue number is wrong, and the original commit
message I found through git blame lists a different, also wrong
issue number... see https://bugs.python.org/issue27122#msg279449

* Fix some deprecation warnings in Doc/conf.py
* Fix an rst error in Misc/NEWS

Update also the Release Schedule to Python 3.7.

If the IRC notification is stored in plaintext, then anyone who forks
the repository and also adds it to travis will send notifications to
the IRC channel for their fork by default. Since the secure variable
is encrypted using a repository specific key, this will only work when
it is being built using the correct repository.

bpo-29527.

This file will be displayed to contributors when they create a pull request in any branch (hence why it is not written in a branch-specific way).

Sorry, I didn't want to push this change before the review :-( I was pushing a
change into the 2.7 branch.

Issue #29100: On Windows, datetime.datetime.fromtimestamp(min_ts) fails with an
OSError in test_timestamp_limits().

Issue #29100: Catch OverflowError in the new test_timestamp_limits() test.

Issue #29100: Fix datetime.fromtimestamp() regression introduced in Python
3.6.0: check minimum and maximum years.

is_size_t test was reversed. Bug spotted by INADA Naoki.

test_unraisable() of test_exceptions expects that PyErr_WriteUnraisable(method)
fails on repr(method).

Before the previous change (7b8df4a5d81d), slot_tp_finalize() called
PyErr_WriteUnraisable() with a PyMethodObject. In this case, repr(method) calls
repr(self) which is BrokenRepr.__repr__() and the calls raises a new exception.

After the previous change, slot_tp_finalize() uses an unbound method: repr() is
called on a regular __del__() method which doesn't call repr(self). repr()
doesn't fail anymore.

PyErr_WriteUnraisable() doesn't call __repr__() anymore, so remove BrokenRepr
unit test.

Issue #29507: Optimize slots calling Python methods. For Python methods, get
the unbound Python function and prepend arguments with self, rather than
calling the descriptor which creates a temporary PyMethodObject.

Add a new _PyObject_FastCall_Prepend() function used to call the unbound Python
method with self. It avoids the creation of a temporary tuple to pass
positional arguments.

Avoiding temporary PyMethodObject and avoiding temporary tuple makes Python
slots up to 1.46x faster. Microbenchmark on a __getitem__() method implemented
in Python:

Median +- std dev: 121 ns +- 5 ns -> 82.8 ns +- 1.0 ns: 1.46x faster (-31%)
