I find three ways to implement handling of the octet-aligned data:

1. Handle the callback function for octet-aligned in  
dissect_ber_external_type(), and make a callback function in x420 to  
handle the data.

2. Make dissect_ber_external_type() run call_ber_oid_callback() for  
octet-aligned data if direct_reference exists.

3. Make x420 handle actx->external.octet_aligned after calling  
dissect_ber_external_type().

I choose to implement number 2 this time, so more dissectors can  
benefit from this change.  I also implement support for calling the  
callback function, while I'm changing the code :)
