+2008/05/02
+	* Changes to map_foreach* functions: [FlavioJS]
+	- removed the unecessary use of va_copy in map_foreachpc
+	- applied the same function pattern to map_foreachmob and map_foreachiddb
+	- created map_foreachnpc
+	- extended the behaviour of map_foreach* functions to stop iterating when func returns -1
+	* 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.
+	* Added a custom implementation of the va_copy macro for systems that don't provide it.
+	* Fixed varargs not being used correctly in foreach() calls in db.c (bugreport:551).
+	* Replaced the integers+checking approach in r12679 with usage of floating point arithmetic.
+	* Applied search&replace to use the new name of the function.
+	* Implemented get_percentage() for compact and safe calculation of percentual values.
+	* Fixed integer arithmetic overflows that were occuring in several supernovice checks (bugreport:1135). [ultramage]

+	* Corrected some x64 compilation warnings in ers/malloc files.
+	* Cleaned up a case of bad variable reuse.
+	* Cleaning up the itemdb reload mess (see r12635, r12643, r12650, r12661, r12662, r12663): [ultramage]
+	- the player data inventory-itemdb index is now refreshed using pc_setinventorydata()
+	- mobdb will no longer initialize with nonexistent items, and mobs will no longer drop them in case of a reload
+	- the clif_buylist() function once again hides invalid npc shop items
+	- it is no longer possible to purchase nonexistent items from a npc shop
+	- npc shop loading will not abort if there is a nonexistent item entry, it will just skip over it
