Moved .progress files into the log directory Moved 'cluster' database tables into the MySQL database, to not have 'cluster' beeing a reserved database name Fixed bug where mysqld got a core dump when trying to use a table created by MySQL 3.23 Fixed some compiler warnings Fixed small memory leak in libmysql Note that this doesn't changeset doesn't include the new mysqldump.c code required to run some tests. This will be added when I merge 5.0 to 5.1
