use logging for nc.py

event keeps a ref to its event_base - needed for later error propagation, and to ensure method calls remain valid

doctweaks and some skeleton tests for event-aliveness

nc.py is now functional enough for basic client use

flesh out nc.py on_connect

experimental getsockopt support in socket - for now only SOL_SOCKET/SO_ERROR

change CallbackEvent to replace fd with ev, event2 doc/style tweaks

qmsk/net/lib/event2/base.pxd

try and keep lib.event2.event objects alive (via self-ref) while pending

fix up circular cimports related to the sockaddr type, and touch up endpoint/getaddrinfo a bit

start writing socket+lib.event2 example (netcat clone), still broken due to lack of refcount magic in event

merge

add CallbackEvent helper, and move getaddrinfo from endpoint into its own function

initial async connect attempt

rename InetAddr to InetAddress

fix getaddrinfo crash in case of errors

fix some segfaults with event

* fix timeout=0.0
* fix loop() return value for case ret == 0, ret > 1
* change event_base to raise EventCallErrors (to be renamed...?)
* move some event docstrings to __call__

some lib.event2 unitests

initial lib.event2 code

reorganize transport.endpoint

move address-family from tcp/socket interface to endpoint interface. The address family of a socket is strictly a property of the address passed to it

add test for IPv6 -> IPv4 connect failure

fix endpoint.InetAddr.resolve

some basic unit tests for tcp

transport.socket fixes

transport.endpoint stuff

fix doctests

fix socket.af_unix to compile
