kamailio-5.x: update to 5.1.6

Minor version bump. Two CVE patches can be removed as they're already
included in the source. One patch was refreshed.

Also:

  - https://sources.openwrt.org is added as primary source URL to lessen
    the load on kamailio upstream
  - Build/Configure is defined as empty (because there is no configure
    script in the source tree
  - patch is added to fix dp_replace(); the function was first added in the
    5.1 release and didn't work; patch was accepted upstream

+    dialplan: fix dp_replace() in cmd_export_t struct
+    
+    In the struct 'int param_no' is set to '2'. But dp_replace() has actually three
+    parameters (dpid, inval, outvar), so kamailio's cfg parser fails when
+    dp_replace() is called:
+    
+    yyparse(): cfg. parser: failed to find command dp_replace (params 3)
+    yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 366, column 45: unknown command, missing loadmodule?
+    
+    This commit fixes 'int param_no' to address this.
