 * Order of sections for common.lib.php:
 *
 * some functions need the constants of libraries/defines.lib.php
 * and defines_mysql.lib.php
 *
 * the PMA_setFontSizes() function must be before the call to the
 * libraries/auth/cookie.auth.lib.php library
 *
 * the include of libraries/defines_mysql.lib.php must be after the connection
 * to db to get the MySql version
 *
 * the PMA_sqlAddslashes() function must be before the connection to db
 *
 * the authentication libraries must be before the connection to db but
 * after the PMA_isInto() function
 *
 * the PMA_mysqlDie() function must be before the connection to db but
 * after mysql extension has been loaded
 *
 * the PMA_mysqlDie() function needs the PMA_format_sql() Function
 *
 * ... so the required order is:
 *
 * - parsing of the configuration file
 * - load of the libraries/defines.lib.php library
 * - load of mysql extension (if necessary)
 * - definition of PMA_sqlAddslashes()
 * - definition of PMA_format_sql()
 * - definition of PMA_mysqlDie()
 * - definition of PMA_isInto()
 * - definition of PMA_setFontSizes()
 * - loading of an authentication library
 * - db connection
 * - authentication work
 * - load of the libraries/defines_mysql.lib.php library to get the MySQL
 *   release number
 * - other functions, respecting dependencies
