Added user level lock functions
            GET_LOCK(string,timeout),
            RELEASE_LOCK(string).
          
            Added Opened_tables to show
            status.
          
            Changed connect timeout to 3 seconds to make it somewhat
            harder for crackers to kill mysqld
            through telnet + TCP/IP.
          
            Fixed bug in range optimiser when using WHERE
            key_part_1 >= something AND key_part_2 <=
            something_else.
          
            Changed configure for detection of
            FreeBSD 3.0 9803xx and above
          
            WHERE with string_col_key =
            constant_string didn't always find all rows if the
            column had many values differing only with characters of the
            same sort value (like e and e with an accent).
          
Strings keys looked up with 'ref' were not compared in case-sensitive fashion.
            Added umask() to make log files
            non-readable for normal users.
          
            Ignore users with old (8-byte) password on startup if not
            using --old-protocol option to
            mysqld.
          
            SELECT which matched all key fields
            returned the values in the case of the matched values, not
            of the found values. (Minor problem.)
