Fix tests that fail when the MySQL's socket file is not /tmp/mysql.sock

and make us prepared for the future.

cosmetics. typedef-ed types should be in capital case

improve the stats subsystem. Reduce the number of macro definitions
in half by smartly introducing 2 new macros. Make MYSQLND::stats a pointer
