From 07f107ae20f60247e716a814ec7bafbda9df945a Mon Sep 17 00:00:00 2001
From: Daniel Stenberg <daniel@haxx.se>
Date: Tue, 14 Dec 2004 09:36:22 +0000
Subject: Moved the engine stuff from the root-level of the SessionHandle
 struct to the UrlState sub-struct. Also made the engine_list exist for
 non-ssl builds to make curl build.
