  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

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)

more general message when slave can't start because of incorrect
replication information, the previous one was sometimes a misleading
indication (i.e. sometimes the problem had nothing to do with
system permissions).
The perfect fix would be to report the exact error to the client
(instead of pointing the client to the error log); this is a bit
of work so it's more a development task:
WL#1088 "Move all hardcoded messages of replication to share/errmsg.txt".
I was not able to modify the errmsg.txt in these sql/ subdirectories:

danish

german
