3.7 - 'asyncio.coroutines' has no attribute 'debug_wrapper'

[sakurai-youhei]

• uvloop version:

root@7013da30e325:/# pip freeze
uvloop==0.9.1

• Python version:

root@7013da30e325:/# python -VV
Python 3.7.0b4 (default, May  5 2018, 02:57:38)
[GCC 6.3.0 20170516]

• Platform:

root@7013da30e325:/# uname -a
Linux 7013da30e325 4.9.87-linuxkit-aufs #1 SMP Wed Mar 14 15:12:16 UTC 2018 x86_64 GNU/Linux

• How to reproduce the bug with PYTHONASYNCIODEBUG in env:

docker run -it --rm python:3.7.0b4 bash
pip install uvloop
PYTHONASYNCIODEBUG=1 python -c "import uvloop"

• Error message:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.7/site-packages/uvloop/__init__.py", line 7, in <module>
    from .loop import Loop as __BaseLoop  # NOQA
  File "uvloop/includes/stdlib.pxi", line 41, in init uvloop.loop
AttributeError: module 'asyncio.coroutines' has no attribute 'debug_wrapper'

• Root cause:
  The asyncio.coroutines.debug_wrapper was dropped in python/cpython@fc2f407#diff-0caeb050855d4e381a842dc66be8c323.
• Proposal of solution:
  Use asyncio.coroutines.CoroWrapper instead because it is used in 3.4, 3.5 and 3.6.

Duplicate with #126. My apologies for spamming.

Fixed in #149. You can now build uvloop from source and test under Python 3.7.
