gpgscm: Simplify hash tables.
* tests/gpgscm/scheme.c (oblist_add_by_name): We now always get a slot. Simplify accordingly. (oblist_find_by_name): Always return the slot. (vector_elem_slot): New function. (new_slot_spec_in_env): We now always get a slot. Remove parameter 'env'. Simplify accordingly. (find_slot_spec_in_env): Always return a slot. (new_slot_in_env): Adapt callsite. (opexe_0): Likewise. (opexe_1): Likewise. (scheme_define): Likewise.
Now that the ill-devised immediate values framework is gone, there is
no need to tag the pointers in vectors anymore. Therefore, we can
always return a pointer to the slot in the hash table lookup
