Patch written by Xavier de Gaye.
(Merge 3.4) Issue #22112, asyncio doc: replace loop.create_task(coro) with
asyncio.async(coro), mention that asyncio.async() can be used to scheduler a
coroutine, and make it clear that create_task() is only available in Python
3.4.2 and later.
Fix usage of the versionchanged directive.

Patch by Akira Li.
#21725: Add RFC 6531 (SMTPUTF8) support to smtpd.

Patch by Milan Oberkirch, developed as part of his 2014 GSOC project.

Note that this also fixes a bug in mock_socket ('getpeername' was returning a
simple string instead of the tuple required for IPvX protocols), a bug in
DebugServer with respect to handling binary data (should have been fixed when
decode_data was introduced, but wasn't found until this patch was written),
and a long-standing bug in DebugServer (it was printing an extra blank line at
the end of the displayed message text).
