     different DN formats

    Fix Description:
    1) In the previous commit 50bb2ee6676e10cdda704982dfa831efa4011037,
    there were 3 places to miss replacing rdn_av_count with subrdn_av_count.
    2) A variable subtypestart is used to keep the head of nested
    multivalued RDNs.  For instance,
       seeAlso=cn\=<CN>\+l\=<L>\,o\=<O>,dc=examle,dc=com
    	       ^   or    ^   or  ^
    There was a bug to set the first position ("cn" in the above example).
    
    In addition, fixed a warning assigning "const char *" to "char *" in
    import_foreman (import-threads.c).
