this will be used to clear up the horrible DN mess.

 Changes between 0.9.4 and 0.9.5  [xx XXX 1999]



  *) New function ASN1_mbstring_copy() this copies a string in either

     ASCII, Unicode, Universal (4 bytes per character) or UTF8 format

     into an ASN1_STRING type. A mask of permissible types is passed

     and it chooses the "minimal" type to use or an error if not type

     is suitable.

     [Steve Henson]



  *) Add function equivalents to the various macros in asn1.h. The old

     macros are retained with an M_ prefix. Code inside the library can

     use the M_ macros. External code (including the openssl utility)
