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

some __cmp__ and doctest love for socket.address

fix up doctests

rename qmsk.net.socket.addr -> qmsk.net.socket.address

socket.setblocking
