hmap: use short version of safe loops if possible.

Using SHORT version of the *_SAFE loops makes the code cleaner and less
error prone. So, use the SHORT version and remove the extra variable
when possible for hmap and all its derived types.

In order to be able to use both long and short versions without changing
the name of the macro for all the clients, overload the existing name
and select the appropriate version depending on the number of arguments.
