Cast away constness at the point where it can't be avoided.

The only reason why we have to cast it away is that C doesn't have a
good framework for creating collections of objects of arbitrary type
(where type includes constness) and we're using a datatype (GHashTable)
implemented and declared in C here.  Do it in the g_hash_table_insert()
call.
