seq_iter: refactoring.

This is needed in preparation for fixing some gc
bugs in iteration in a less hacky way.

* lib.h (struct seq_iter): Members get and peek removed,
replaced by ops pointer.
(struct seq_iter_ops): New struct type.
(seq_get, seq_peek): Call get and peek through ops table.

* lib.c (seq_geti): Refer to get through ops.
(si_null_ops, si_list_ops, si_vec_ops, si_hash_ops,
si_tree_ops, si_range_cnum_ops, si_range_chr_ops,
si_range_bignum_ops, si_range_str_ops, si_rev_range_cnum_ops,
si_rev_range_chr_ops, si_rev_range_bignum_ops,
si_rev_range_str_ops, si_chr_ops, si_num_ops, si_oop_ops,
si_fast_oop_ops): New static structures.
(seq_iter_init_with_info): Point new ops member of seq_iter to
one of the new structures. Remove initializations of get and
peek.
