[Serusers] xmlrpc calls

[Jan Janak]

The function expects two parameters, the first one is the name of the
table ("location" in your case) and the 2nd parameter is AOR (Address Of
Record), the XML-RPC request should look like this:

<?xml version=\"1.0\"?>
<methodCall>
<methodName>usrloc.show_contacts</methodName>
<params>
<param>
  <value><string>location</string></value>
</param>
<param>
  <value><string>jan at iptel.org</string></value>
</param>
</params>
</methodCall>

Here is how you could find out what parameters does the function expect:

Open ul_rpc.c and lookup function rpc_show_contacts.
The function contains the following code at the beginning:

if (rpc->scan("SS", &t, &aor) < 0) return;

Function scan reads and parses the parameters. In this particular example
you can see that the function expects two string parameters (hence
double S in the formatting string) and from the name of the variables
you could guess that the first one is the table name (well, t is not
very descriptive, I admit), and the 2nd one is AOR.
