cba48c7d46 Fix a race condition in the dns/bufferevent_connect_hostname test. 
As originally written, the test would only pass if the accept()
callbacks for the evconnlistener were all invoked before the last of
the CONNECTED/ERROR callbacks for the connecting/resolving bufferevent
had its call to event_base_loopexit() complete.  But this was only
accidentally true in 2.0, and might not be true at all in 2.1 where
we schedule event_base_once() callbacks more aggressively.

ecfc720a4f Make evconnlistener work around bug in older Linux when getting nmapped 
Older Linuxes sometimes respond to some nmap probes by having accept()
return a success but with socklen 0.  That can lead to confusing behavior
when you go to process the sockaddr.

27e222559a Add evbuffer_copyout_from to copy data from the middle of a buffer 
You could previously do this with evbuffer_peek() and some memcpys,
but it was a bit more work than most folks wanted to get into.

35c5c9558a Bypass event_add when using event_base_once() for a 0-sec timeout 
Some people use event_base_once(EV_TIMEOUT) to make a callback get
called "immediately".  But this is pretty roundabout: it uses the
timeout heap to immediately put the event onto the active queue, when
it could just use event_active.  Additionally, it can lead to
surprising re-ordering behavior.

This patch changes event_base_once so it bypasses event_add() and
called event_active() directly on a pure-timeout event with an empty
timeout.

11f36a5f76 Be absolutely sure to clear pncalls before leaving event_signal_closure 
I thought we'd fixed the cases where this could come up, but
apparently having an event_base_break() happen while processing
signal events could get us in trouble.

2aa036fa04 Avoid spinning on OpenSSL reads 
Previously, if some sender were generating data to read on an
OpenSSL connection as fast as we could process it, we could easily
wind up looping on an openssl do_read operation without ever
considering other sockets.

The difference between this and the original method in
consider_reading() is that it only loops for a single completed
*frame* instead of looping until fd is drained or an error condition
was triggered.
