This patch splits the formerly windows-only case of evutil_socketpair()
into an (internal-use-only) function named evutil_ersatz_socketpair(), and
makes it build and work right on non-Windows hosts.
We need this for convenience to test sendfile on solaris, where socketpair
can't give you an AF_INET pair, and sendfile() won't work on AF_UNIX.
It turns out that the happy fun Linux kernel is deprecating sysctl,
and using sysctl to fetch entropy will spew messages in the kernel
logs. Let's not do that. Instead, let's call sysctl for our
entropy only when all other means fail.
Additionally, let's add another means, and try
/proc/sys/kernel/random/uuid if /dev/urandom fails.
The old logging code was littered with places where we stored messages in
static char[] fields. This is fine in a single-threaded program, but if you
ever tried to log evdns messages from two threads at once, you'd hit a race.
This patch also refactors evdns's debug_ntop function into a more useful
evutil_sockaddr_port_format() function, with unit tests.
If the user sets a bind address to use for nameservers, and a
nameserver happens to be on 127.0.0.1, the nameserver will generally
fail. This patch alters this behavior so that the bind address is
only applied when the nameserver is on a non-loopback address.
The entry points are evutil_getaddrinfo and evdns_getaddrinfo respectively.
There are fairly extensive unit tests.
I believe this code conforms to RFC3493 pretty closely, but there are
probably more issues. It should get tested on more platforms.
This code means we can dump the well-intentioned but weirdly-implemented
bufferevent_evdns and evutil_resolve code.
svn:r1537
This function, bufferevent_socket_connect_hostname() can either use
evdns to do the resolve, or use a new function (evutil_resolve) that
uses getaddrinfo or gethostbyname, like http.c does now.
This function is meant to eventually replace the hostname resolution mess in
http.c.

The big difference here is that EVUTIL_ASSERT() passes its message on
via event_errx() before aborting, so that the application has a prayer
of noticing and recording it.
svn:r1463
This code adds a new Bufferevent type that is only compiled when the
openssl library is present. It supports using an SSL object and an
event alert mechanism, which can either be an fd or an underlying
bufferevent.
There is still more work to do: the unit tests are incomplete, and we
need to support flush and shutdown much better. Sometimes events are
generated needlessly: this will hose performance.
There's a new encrypting proxy in sample/le-proxy.c.
This code has only been tested on OSX, and nowhere else.
svn:r1382
This patch adds a new set of EVUTIL_IS* functions to replace use of
the ctypes is* functions in all cases where we care about characters'
interpretations in net ascii rather than in the locale. For example,
when we're working with DNS hostnames, we don't want to do the 0x20
hack on non-ascii characters, even if the host thinks they should be
isalpha.

a) this is 2009
b) niels and nick have been comaintainers for a while
c) saying "all rights reserved" when you then go on to explicitly
disclaim some rights is sheer cargo-cultism.
