Reduce header interdependencies, initially in engine.h (the rest of the

changes are the fallout). As this could break source code that doesn't
directly include headers for interfaces it uses, changes to recursive
includes are covered by the OPENSSL_NO_DEPRECATED symbol. It's better to
define this when building and using openssl, and then adapt code where
necessary - this is how to stay current. However the mechanism exists for
the lethargic.

  Changes between 0.9.7c and 0.9.8  [xx XXX xxxx]
 
+  *) Reduced header interdepencies by declaring more opaque objects in
+     ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
+     give fewer recursive includes, which could break lazy source code - so
+     this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
+     developers should define this symbol when building and using openssl to
+     ensure they track the recommended behaviour, interfaces, [etc], but
+     backwards-compatible behaviour prevails when this isn't defined.
+     [Geoff Thorpe]
+
   *) New function X509_POLICY_NODE_print() which prints out policy nodes.
