Just as with the OPENSSL_malloc calls, consistently use sizeof(*ptr)
for memset and memcpy.  Remove needless casts for those functions.
For memset, replace alternative forms of zero with 0.

For a local variable:
        TYPE *p;
Allocations like this are "risky":
        p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption.  Instead do this:
        p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.

After the finale, the "real" final part. :)  Do a recursive grep with
"-B1 -w [a-zA-Z0-9_]*_free" to see if any of the preceeding lines are
an "if NULL" check that can be removed.

Don't check for NULL before calling a free routine.  This gets X509_.*free:
    x509_name_ex_free X509_policy_tree_free X509_VERIFY_PARAM_free

Some of the #if 0 code in demo's was kept, but given helpful #ifdef
names, to show more sample code.

Delete X509_POLICY_REF code.

Fix handling of invalid policy extensions to return the correct error.

Add command line option to inhibit policy mappings.

Inhibit any policy count should ignore self issued certificates.
Require explicit policy is the number certificate before an explict policy
is required.

Ignore self issued certificates when checking path length constraints.

Duplicate OIDs in policy tree in case they are allocated.

Use anyPolicy from certificate cache and not current tree level.

Fix additional gcc 4.2 value not used warnings.

I'll remember to try to compile this with warnings enabled next time :-)

This is currently *very* experimental and needs to be more fully integrated
with the main verification code.
