Fix bug: FOREIGN KEY ... ON UPDATE/DELETE NO ACTION must check the foreign key constraint, not ignore it. Peter Gulutzan said that NO ACTION should check the constraint as deferred, at the end of the SQL statement, while RESTRICT should check it immediately. Since we do not have defered constraints in InnoDB, this bug fix makes InnoDB to check NO ACTION constraints immediately, like it checks RESTRICT constraints.

  DO NOT MERGE TO 4.1: charset changes can cause problems in a downgrade 4.1.1 -> 4.0.18

I had not corrected these languages.
As it has been discussed with the docs team, the new messages will be merged
to 4.1, and then will be translated in 4.1 (they will remain in English
in 4.0).

  DO NOT MERGE TO 4.1: add code for automatic downgrade 4.1.1 -> 4.0 if the user has not created multiple tablespaces yet

(acctually i don't like the fix, any suggestions?)

Added support for lower_case_table_names=2, which is to be used on case insensitive file systems.
This tells MySQL to preserve the used case of filenames and database names to make it esier to move files between cases sensitive can case insensitive file systems (like Windows and Linux)

  Do not assert in log0log.c, line 856 if ib_logfiles are too small for innodb_thread_concurrency. Instead, print instructions how to adjust my.cnf and call exit(1).
