Replaced the very ineffective clif_foreachclient() with map_foreachpc() since they essentially do the same thing (bugreport:1174).

Rewrote map_foreachpc() so that its callback function signature now uses a more natural 'sd' instead of a DBKey/void* pair.
Rewrote atcommand_users() to use a single function, instead of depending on two helper functions and global objects.
