Proposal to fix this problem: when using libmysqlclient, you must call mysql_server_end() to nicely free memory at the end of your program; it however
sounds weird to call a function named *SERVER_end* when you're the CLIENT (you're not ending the server, you're ending your ability to talk to servers).
So here I add two defines which should be more generic names. This was longly discussed with Konstantin, Serg, Brian. The problem started from
a post on valgrind-users list: http://sourceforge.net/mailarchive/forum.php?thread_id=5778035&forum_id=32038 ; our manual mentions these functions
only for libmysqld API so needs some fixing, and then we can close BUG#8099 and BUG#6149.
