libctf: add hash traversal helpers
There are two, ctf_dynhash_iter and ctf_dynhash_iter_remove: the latter
lets you return a nonzero value to remove the element being iterated
over.
Used in the next commit.
libctf/
* ctf-impl.h (ctf_hash_iter_f): New.
(ctf_dynhash_iter): New declaration.
(ctf_dynhash_iter_remove): New declaration.
* ctf-hash.c (ctf_dynhash_iter): Define.
(ctf_dynhash_iter_remove): Likewise.
(ctf_hashtab_traverse): New.
(ctf_hashtab_traverse_remove): Likewise.
(struct ctf_traverse_cb_arg): Likewise.
(struct ctf_traverse_remove_cb_arg): Likewise.
