Alterações na distribuição 3.22.1 (Jun 1998: Alpha)

Added new C API function mysql_ping().

• Added new API functions mysql_init() and mysql_options(). You now MUST call mysql_init() before you call mysql_real_connect(). You don't have to call mysql_init() if you only use mysql_connect().
• Added mysql_options(...,MYSQL_OPT_CONNECT_TIMEOUT,...) so you can set a timeout for connecting to a server.
• Added --timeout option to mysqladmin, as a test of mysql_options().
• Added AFTER column and FIRST options to ALTER TABLE ... ADD columns. This makes it possible to add a new column at some specific location within a row in an existing table.
• WEEK() now takes an optional argument to allow handling of weeks when the week starts on Monday (some European countries). By default, WEEK() assumes the week starts on Sunday.
• TIME columns weren't stored properly (bug in MariaDB Version 3.22.0).
• UPDATE now returns information about how many rows were matched and updated, and how many warnings occurred when doing the update.
• Fixed incorrect result from FORMAT(-100,2).
• ENUM and SET columns were compared in binary (case-sensitive) fashion; changed to be case-insensitive.
