call_other - call a function in another object

mixed call_other(mixed ob, string func, ...); 

mixed call_other(mixed ob, array args); 

mixed call_other(array obs, string func, ...); 

mixed call_other(array obs, array args); 

ob is either an object pointer, or a string filename (suitable for 
find_object()).  obs is an array of object pointers and strings.
Using an array as the first argument does a call_other for each element of
the array, and returns an array of the results.
If the array form is used for args, then the first element is the function
name, and the remainder are the arguments; e.g.:

call_other(ob, ({ "foo", 1, 3, 5 }))

and

call_other(ob, "foo", 1, 3, 5)

are equivalent.  The function foo() is called in the object ob with the
arguments (1, 3, 5).  The return value of call_other() is the value
returned from the foo() function.  In the case of an array of objects,
the return value of call_other() is an array of the return values.

There is a much more attractive way to do call_others;
call_other(x, "y", z, ...) is the same as:

x->y(z, ...)

ie,

call_other(ob, "query_name");

could be written as:

ob->query_name();

Writing out the call_other call is mainly used when the function name
is in a variable, i.e:

<pre>
void do_test(string fname, int x) {
    call_other(fname, "test_" + x);
}
</pre>

An example of using an array as the first argument:

users()->quit();
