I think that hashtabs should never be obstack-allocated. In the past this was convenient sometimes, because any new data structure needed a corresponding cleanup. However, with the switch to C++, resource management has become much simpler; for example, a local variable can simply be of type htab_up rather than hashtab_t, and the problem is solved. This patch removes hashtab_obstack_allocate to try to prevent this anti-pattern from being used again.
