wsgi: Fix handling partial writes on Python 3partial-write-fix-2

Closes https://github.com/eventlet/eventlet/issues/295 (in the wsgi
module we use a custom writelines implementation now).

Those write() calls might write only part of the data (and even if they
don't - it's more readable to make sure all data is written
explicitly).

I changed the test code so that the write() implementation returns the
number of characters logged and it cooperates nicely with writeall()
now.
