After merge fixes

Add warnings for single line inserts. To do this I had to convert count_cuted_fields to an enum (to be able to detect setting a NOT NULL field to NULL)

query_alloc_block_size, query_prealloc_size, range_alloc_block_size,transaction_alloc_block_size and transaction_prealloc_size
Add more checks for "out of memory" detection in range optimization

Remove wait_if_global_read_lock on commit as this can cause deadlocks

More tests cases
After merge fixes

   4.0->4.1 merge (mysqltest needs to be linked with a C++ compiler)

Changed --remote to --read-from-remote-server (mysqlbinlog)

  Character set variables test

into narttu.mysql.fi:/my/mysql-4.0

as the test is meaningful only if the slave supports transactions,
we require this. As in 4.0 the slave runs with --skip-innodb, we
test for BDB.

  Multiple tablespaces for InnoDB

  Tell explicitly that InnoDB should retrieve all columns in CHECKSUM TABLE
