Added two keyword arguments, `delay` and `interleave`, to
`BaseEventLoop.create_connection`. Happy eyeballs is activated if
`delay` is specified.
We now have documentation for the new arguments. `staggered_race()` is in its own module, but not exported to the main asyncio package.

Given example does not run, loop variable is missing.
Secondly, this is bad example how to handle shutdown signal, because it would cause `RuntimeError: Event loop stopped before Future completed.`
Perhaps it would be better to cancel all tasks instead of closing loop directly?
Did not create issue, because question is quite simple.
* Implement C14N 2.0 as a new canonicalize() function in ElementTree.
Missing features:
- prefix renaming in XPath expressions (tag and attribute text is supported)
- preservation of original prefixes given redundant namespace declarations
* bpo-36673: Implement comment/PI parsing support for the TreeBuilder in ElementTree.
* bpo-36673: Rewrite the comment/PI factory handling for the TreeBuilder in "_elementtree" to make it use the same factories as the ElementTree module, and to make it explicit when the comments/PIs are inserted into the tree and when they are not (which is the default).
Document that subprocess.Popen no longer raise an exception on error
like missing program on very specific platforms when using
os.posix_spawn() is used.
# [bpo-36651](https://bugs.python.org/issue36651): Fixed Asyncio Event Loop documentation inconsistency
In the documentation for the call_later and the call_at methods there is a note which says that the delay cannot be longer than a day, but both methods have a note saying that this limitation was removed in Python 3.8
Here I fixed this issue by removing the pre-exising note and added a versionchanged.
To test my changes I have rebuilt the documentation with ```make html```. I did not have any errors and the effected page displayed correctly on a browser.

The imap.IMAP4.logout() method no longer ignores silently arbitrary
exceptions.
Changes:
* The IMAP4.logout() method now expects a "BYE" untagged response,
rather than relying on _check_bye() which raises a self.abort()
exception.
* IMAP4.__exit__() now does nothing if the client already logged out.
* Add more debug info if test_logout() tests fail.
Add new keyword arguments "default_namespace" and "xml_declaration" to functions ET.tostring() and ET.tostringlist(), as known from ElementTree.write().
For BufferedReader and BufferedWriter, seek and tell operations are
optional (they may or may not exist based on the underlying stream). For
BufferedRandom, they are mandatory: a BufferedRandom should not be
constructed over an unseekable underlying stream. Document this.
On AIX, sys.platform doesn't contain the major version anymore.
Always return 'aix', instead of 'aix3' .. 'aix7'. Since
older Python versions include the version number, it is recommended to
always use sys.platform.startswith('aix').
Move all documentation regarding the readinto method into either io.RawIOBase or io.BufferedIOBase.
Corresponding changes to documentation in the _pyio.py module.
It turns out doing socket.listen(0) does not equal to "choose a
reasonable default". It actually means "set backlog to 0".
As such set backlog=None as the default for socket.create_server.
Fixes the following BB failures:
