Ok. First attempt to get this done.

I've created a new core cfg parameter "log_assign_actions" to
activate/deactivate de log. No problem there.

I've created to new functions on lvalue.c in order to log the assign
action on lval_assign()

questions:
- How can I get the name of the pvar if I only have pv_spec_t struct?
- Why is always called log_assign_action_pvar() with this kamailio.cfg example?

        xdbg("test assign_action: $$var(temp) = $$fu;\n");
        $var(temp) = $fu;
        xdbg("test assign_action: $$var(temp) = $$null;\n");
        $var(temp) = $null;
        xdbg("test assign_action: $$var(temp) = 2;\n");
        $var(temp) = 2;
        xdbg("test assign_action: $$avp(s:temp_avp) = $$si;\n");
        $avp(s:temp_avp) = $si;
        xdbg("test assign_action: $$avp(s:temp_avp) = \"hi\";\n");
        $avp(s:temp_avp) = "hi";
        xdbg("test assign_action: $$avp(s:temp_avp) = 3;\n");
        $avp(s:temp_avp) = 3;
