If there exists a situation in wich order is relevant then we can define an
iterator type over the keys or elements instead of the "pdf_hash_mapkeys()"
function.

Something like:

'pdf_status_t pdf_hash_iterator (hash_table, order_type, itr_pointer)'

and

'pdf_status_t pdf_hash_iterator_next (itr_pointer, next_key / next_element)'

I agree.

I'll add the rest of the functions you suggested.
