Expands every "ANY DEFINED BY" element of a structure created from
a DER decoding process (asn1_der_decoding function). The element
ANY must be defined by an OBJECT IDENTIFIER. The type used to
expand the element ANY is the first one following the definition of
the actual value of the OBJECT IDENTIFIER.
ASN1_SUCCESS if Substitution OK, ASN1_ERROR_TYPE_ANY if
some "ANY DEFINED BY" element couldnt be expanded due to a
problem in OBJECT_ID -> TYPE association, or other error codes
depending on DER decoding.
