Add getters for X509_STORE and X509_OBJECT members

OpenSSL 1.1.0-pre5 has made some additional structs opaque. Python's ssl
module requires access to some of the struct members. Three new getters
are added:

int X509_OBJECT_get_type(X509_OBJECT *a);
STACK_OF(X509_OBJECT) *X509_STORE_get0_objects(X509_STORE *v);
X509_VERIFY_PARAM *X509_STORE_get0_param(X509_STORE *ctx);

+
+ X509_VERIFY_PARAM *X509_STORE_get0_param(X509_STORE *ctx);

+
+=head1 DESCRIPTION
+
+X509_STORE_set1_param() sets the verification parameters
+to B<pm> for B<ctx>.
+
+X509_STORE_get0_param() retrieves an internal pointer to the verification
+parameters for B<ctx>. The returned pointer must not be freed by the
+calling application
+
+X509_STORE_get0_objects() retrieve an internal pointer to the store's
+X509 object cache. The cache contains B<X509> and B<X509_CRL> objects. The
+returned pointer must not be freed by the calling application.
+
+
+=head1 RETURN VALUES
+
+X509_STORE_get0_param() returns a pointer to an
+B<X509_VERIFY_PARAM> structure.
+
+X509_STORE_set1_param() returns 1 for success and 0 for failure.
+
+X509_STORE_get0_objects() returns a pointer to a stack of B<X509_OBJECT>.
