SYNOPSIS
create_subpartition_name()
out:out Created partition name string
out:out The buffer for the created partition name string
must be *at least* of FN_REFLEN+1 bytes
in1 First part
in2 Second part
in3 Third part
name_variant Normal, temporary or renamed partition name
RETURN VALUE
NONE
0 if ok, error if name too long
DESCRIPTION
This method is used to calculate the subpartition name, service routine to
the del_ren_cre_table method.
