all watchers now behave like they did in 0.13: the incref themselves while in use by the event loop (that is, _ref versions are kept but without _ref in the name)

one reason for that is that doing ev_watcher_stop in watcher's __dealloc__ crashes: loop attribute is no longer a valid reference in __dealloc__; (although this could probably be worked around)

another reason is to make it simpler, having 2 sets of watchers is complex to explain.

third reason is: using watchers that automatically stopped themselves on __dealloc__ introduced a lot
of incompatibilities and potentially unexpected behaviour compared to gevent-0.13. it is also not recommended in general to depend on CPython's refcounting for resource management.

pywsgi: set SERVER_NAME and SERVER_PORT only once after socket is bound; do not overwrite SOCKET_NAME and SOCKET_PORT provided by the user; do not fail on unix sockets (use '' in that case)

add 'wfile' as a deprecated property

core_.pyx: use <void*> instead of <object>, because cython 0.14.1 will add additional incref/decref for <object> arguments
