[Vala] GLib binding missing: GLib.Once and bit locking are missing

[Tal Hadad <tal_hd hotmail com>]

After looking on this page:
http://developer.gnome.org/glib/2.31/glib-Threads.html
I see that those useful thread-safe binding are missing:
* GLib.Once namespace and its methods.
* g_bit_lock, g_bit_try_lock and g_bit_unlock in GLib.AtomicInt
* g_pointer_lock, g_pointer_try_lock and g_pointer_unlock in GLib.AtomicPointer

Please fix them on the next release.

Yours
Tal
