[glib] Add g_assert_true, g_assert_false and g_assert_null

[Matthias Clasen <matthiasc src gnome org>]

commit b63739e60ea03364a7a06e0c697b5c6c4690d0b6
Author: Matthias Clasen <mclasen redhat com>
Date:   Sat Feb 2 12:53:05 2013 -0500

    Add g_assert_true, g_assert_false and g_assert_null
    
    These are just like g_assert(), but using a different entry
    point for the message, so we can repurpose them together
    with the other assertion macros.
