Converts a pointer to a #gint to a hash value.
It can be passed to g_hash_table_new() as the @hash_func parameter,
when using non-%NULL pointers to integer values as keys in a #GHashTable.
Note that this function acts on pointers to #gint, not on #gint
directly: if your hash table's keys are of the form
GINT_TO_POINTER (n), use g_direct_hash() instead.
