Stop crashing in evdns when nameserver probes give a weird error
...
When a nameserver is down, we periodically try sending a "probe"
message to that nameserver to see if it has come back up. If a
nameserver comes up, we cancel any pending probe messages.
Cancelling a probe message while handling the probe's response would
result in a access-after-free or a double-free, so when we notice that
we're about to call a nameserver up because of having received a probe
from it, we need to check whether current response is the response
from the probe.
There was a case where we didn't to that, though: when the resolver
gave us an unusual error response to our request that it resolve
google.com. This is pretty rare, but apparently it can happen with
some weird cacheing nameservers -- the one on the mikrotik router, for
example. Without this patch, we would crash with a NULL pointer
derefernce.
Thanks to Hannes Sowa for finding this issue and helping me track it
down.

Tweak the evutil_open_closeonexec patch to work on windows, old unixes.

Windows doesn't have a mode_t as far as I can tell.
Some unixes, iirc, don't like three-argument open without O_CREAT.

Infrastructure for using faster/fewer syscalls when creating sockets
...
Linux provides some features that allow avoiding extra calls to
fcntl when creating new nonblocking/close-on-exec sockets, so
we can add wrapper functions to emulate those when they are not
available.
Additionally, even when we are emulating those functions, we can
take a fast path that cuts our fcntl calls in half: we don't need to
look up the previous value of a file's flags when we have just
created it.

In the kqueue backend, do not report EBADF as an EV_READ
...
We were doing this because of (correct) reports that NetBSD gives an
EBADF when you try to add the write side of a pipe for which the
read side has been closed. But on most kqueue platforms, that
doesn't happen, and on *all* kqueue platforms, reporting a
nonexistent fd (which we usually have if we have seen EBADF) as
readable tends to give programs a case of the vapors.
Nicholas Marriott wrote the original patch here; I did the comment
fixes.

This is not a perfect fix, but it's much much better than the
current buggy behavior, which could lead to filtering SSL
connections that just stopped reading.
