Changes between 0.9.7e and 0.9.8 [xx XXX xxxx]
+ *) New structure X509_VERIFY_PARAM which combines current verify parameters,
+ update associated structures and add various utility functions.
+
+ Add new policy related verify parameters, include policy checking in
+ standard verify code. Enhance 'smime' application with extra parameters
+ to support policy checking and print out.
+ [Steve Henson]
+
*) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
Nehemiah processors. These extensions support AES encryption in hardware
as well as RNG (though RNG support is currently disabled).

+ * The "inh_flags" field determines how this function behaves.

+ * Normally any values which are set in the default are not copied from the
+ * destination and verify flags are ORed together.
+ *
+ * If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied
+ * to the destination. Effectively the values in "to" become default values
+ * which will be used only if nothing new is set in "from".
+ *
+ * If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether
+ * they are set or not. Flags is still Ored though.
+ *
+ * If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead
+ * of ORed.
+ *
+ * If X509_VP_FLAG_LOCKED is set then no values are copied.
+ *
+ * If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed
