[Vala] Error in glib-2.0.vala binding of g_strdup_printf

["Cayle Graumann" <cayle graumann gmail com>]

Jurg,

    Thanks for all the advice.  Moving everything to the vapi dir worked well.  But in duplicating one of the GenX simple demos to test the new binding, 
I discovered another small error in the glib bindings.

The binding for string.printf should be made static, since g_strdup_printf does not take the object as it's first argument. 

(Line 175 vapi/glib-2.0.vala)

[CCode (cname = "g_strdup_printf")]
public static ref string printf (...);

Guys, keep up the good work.
