instead of making it experimental.

Remove the extra line which try to use the name INNOBASE again. The IF ELSE
loop above declares the library name based on the version of mysql

                     grants are reapplied.


After renaming a user and trying to re-apply grants results in additional
grants.

This is because we use username as part of the key for GRANT_TABLE structure.
When the user is renamed, we only change the username stored and the hash key
still contains the old user name and this results in the extra privileges

Fixed by rebuilding the hash key and updating the column_priv_hash structure
when the user is renamed

There are some problems about help text:
- It is stated that "auto" is the default twice. It need be stated only once.
- It is stated that --base64-output is short for --base64-output=always. But that sounds
like the default is "always", not "auto".

Make the help text clear as following:
Determine when the output statements should be base64-encoded BINLOG 
statements: 'never' disables it and works only for binlogs without 
row-based events; 'auto' prints base64 only when necessary (i.e., 
for row-based events and format description events); 'always' prints 
base64 whenever possible. 'always' is for debugging only and should 
not be used in a production system. If this argument is not given, 
the default is 'auto'; if it is given with no argument, 'always' is used.

Problem: the "caseinfo" member of CHARSET_INFO structure was not
initialized for user-defined Unicode collations, which made the
server crash.
Fix: initializing caseinfo properly.
