Summary: Add new assignment operator (:=) to config script

Initial Comment:
find attached a patch which adds a new assignment operator (:=) to the config 
script. Instead of the regular assignment (=), this operator will not add an 
entry to an existing avp, but it deletes the existing avp and creates a new 
avp with only one value.

I think this is usefull because I was using a lot of avp_delete()/assignment 
sequences to keep just 1 value in an avp instead of a list.

Please review and comment on it. Although the patch seems to work ok, I don't 
have any insight in the pointer dances OpenSER does, so I might have done 
something completely insane.

If the patch is acceptable as is, please commit.

Patch is against OpenSER 1.2 svn revision 2606


Config example and result:
route {
        xlog("Part 1");
        $avp(s:test1) = "test1_1";
        $avp(s:test1) = "test1_2";
        $avp(s:test2) := "test2_1";
        $avp(s:test2) := "test2_2";
        avp_print();

        xlog("Part 2");
        $avp(s:test1) := "test1_3";
        $avp(s:test2) = "test2_3";
        avp_print();
}
