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
Rename mix_innodb_myisam_binlog-master.opt; when the test was moved to
separate stm/row test cases, the .opt were not moved along with it,
causing a 60-second test duration because of default lock timeout :-(
