Jakub Stasiak 449c90a509 Python 3 compat: Fix all Travis test failures
This patch consists of the following changes:

* Splitting eventlet.greenio into base, py2 and py3 parts
  (eventlet.greenio should be exporing the same public objects). This
  change is motivated by the size and the number of conditions present
  in the current greenio code
* Connected to the first point: implementing almost completely new
  GreenPipe callable utilizing parts of old GreenPipe code but dropping
  _fileobject/SocketIO inheritance in favour of io.FileIO and making use
  of patched _pyio.open function which wraps raw file-like object in
  various readers and writers (they take care of the buffering,
  encoding/decoding etc.)
* Implementing (from scratch or updating existing versions)
  green versions of the following modules:

  * http.* (needed by Python 3's urllib)
  * selectors (Python >= 3.4, used in subprocess module)
  * urllib.* (needed by various tests and we were already exposing green
    urllib)

* Modifying some tests to make tests pass, which includes:

  * unicode/bytestring issues
  * modifying wsgi_test_conntimeout.py to not pass bufsize and close
    arguments to ExplodingSocketFile - on Python 3 it inherits from
    SocketIO, which doesn't deal with buffering at all as far as I can
    see

* Random cleaning up and reorganizing
* Requiring Python 3.x tests to pass for the whole build to pass

Known issues:

* code repetition
* naming inconsistencies
* possibly breaking some external code using private eventlet.greenio attributes

Closes https://github.com/eventlet/eventlet/issues/108

Affects https://github.com/eventlet/eventlet/issues/6 (I'd call it an
experimental support)

"""Test than modules in eventlet.green package are indeed green.
To do that spawn a green server and then access it using a green socket.
If either operation blocked the whole script would block and timeout.
