* This re-implements g_str_hash as it was prior to glib2-2.28:
*
* http://git.gnome.org/browse/glib/commit/?id=354d655ba8a54b754cb5a3efb42767327775696c
*
* Note that the new g_str_hash is presumably a *better* hash (it's actually
* a correct implementation of DJB's hash), but we need to preserve existing
* behaviour, because the hash key ultimately determines the "sort" order
* when iterating through GHashTables, which affects allocation of scores to
* clone instances when iterating through rsc->allowed_nodes. It (somehow)
* also appears to have some minor impact on the ordering of a few
* pseudo_event IDs in the transition graph.
