            Avoid deprecation warnings raised on import

This fixes the matplotlib's test_correct_key which has started failing
due to DeprecationWarning from this package treated as errors.

+Subject: [PATCH] De-duplicate deprecations of module attributes
+
+This allows generically deprecating a set of symbols (e.g., everything
+in `GLibUnix` that's in `GLib`) and then providing a more-specific
+deprecation for special symbols (e.g., `GLib.unix_signal_add_full`),
+without triggering a deprecation from the first when making the second.
