        [GTK] Clean up usage of NULL in webkitwebframe.cpp
        https://bugs.webkit.org/show_bug.cgi?id=51685

        Replace occurrences of NULL with 0, in webkitwebframe.cpp. Not all
        uses of NULL have been changed, as certain GLib functions require
        an explicit NULL as a sentinel.

        * webkit/webkitwebframe.cpp:
        (webkit_web_frame_get_data_source_from_core_loader):
        (webkit_web_frame_class_init):
        (webkit_web_frame_new):
