2015-06-14hashmap: fix iterators to not skip entriesDavid Herrmann
Currently, the HASHMAP iterators stop at the first NULL entry in a hashmap. This is non-obvious and breaks users like sd-device, which legitimately store NULL values in a hashmap. Fix all the iterators by taking a pointer to the value storage, instead of returning it. The iterators now return a boolean that tells whether the end of the list was reached. Current users of HASHMAP_FOREACH() are *NOT* changed to explicitly check for NULL. If it turns out, there were users that inserted NULL into hashmaps, but didn't properly check for it during iteration, then we really want to find those and fix them.
