Closes: #617 (cherry-pick)
(cherry picked from commit 28b8075400c70b2d2da2ce07e590c2ec6d11783d)
Before it depends from the caller #include appropriate headers (at least
for OPENSSL_VERSION_NUMBER), but let's make it independent.
Fixes: #574
(cherry picked from commit c2c08e0203da93938fe35234fa3a1be4d1c3c2e1)
OpenSSL has a per-thread error stack, and really doesn't like you
leaving errors on the stack. Rather than discard the errors or force
the user to handle them, this patch pulls them off the openssl stack
and puts them on a stack associated with the bufferevent_openssl. If
the user leaves them on the stack then, it won't affect any other
connections.
This bug was found by Roman Puls. Thanks!

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.
