Looks up a key in the GLib.HashTable, returning the original key and the
associated value and a gboolean which is true if the key was found. This
is useful if you need to free the memory allocated for the original key,
for example before calling g_hash_table_remove().
You can actually pass null for lookup_key to test
whether the null key exists, provided the hash and equal functions
of hash_table are null-safe.
