Use version-based GLib/GDK/GTK+ warnings.

Use GLIB_VERSION_MAX_ALLOWED and GDK_VERSION_MAX_ALLOWED to warn if we
accidentally use symbols that were introduced in versions subsequent to
our minimum requirement.

Use GLIB_VERSION_MIN_REQUIRED and GDK_VERSION_MIN_REQUIRED to suppress
deprecation warnings by version so we can clean them up incrementally.
The initial values produce no deprecation warnings.
