url: always access req._tunnel_host
The getattr() was there to handle Python versions before 2.6, which
lacked this attribute.
We /might/ be able to further delete some code here. However, the
behavior here is extremely hard to follow because large parts of
this code duplicate code from the Python standard library and it
is difficult to understand what is actually needed.
