Author: Dr. Matthias St. Pierre <Matthias.St.Pierre at ncp-e.com>

    Add missing accessors for X509 AuthorityKeyIdentifier
    
    Complements commit b383aa208146, which added X509_get0_authority_key_id().
    
     const ASN1_OCTET_STRING *X509_get0_authority_key_id(X509 *x);
     const GENERAL_NAMES *X509_get0_authority_issuer(X509 *x);      [NEW]
     const ASN1_INTEGER *X509_get0_authority_serial(X509 *x);       [NEW]

 X509_set_proxy_flag() marks the certificate with the B<EXFLAG_PROXY> flag.
 This is for the users who need to mark non-RFC3820 proxy certificates as
 such, as OpenSSL only detects RFC3820 compliant ones.
