amajorek 41ef54f570 New eventlet.common module to create version-neutral layer. For now only get_errno added there.
All usage of e[0] replaced with either get_errno(e) or e.args[0] if intnetion was not to extract errno, but first argument

socket.error in <2.5 does not have errno attribute
socket.error in 3.x does not allow indexing access
e.args[0] works for all.
There are cases when args[0] is not errno.
i.e. http://bugs.python.org/issue6471
Maybe there are cases when errno is set, but it is not the first argument?
