In acl_getroot_no_password(), use a separate variable for traversing the acl_users list so that the last entry is not used when no matching entries are found.

- Cleanup typo.
- Make sure to only embedded four part numberic version.

Problem: we may create a deadlock committing changes in the mysql_alter_table() when 
LOCK_open is set. Moreover, "in some variants of the ALTER TABLE commit
happens earlier, outside of LOCK_open, in other later - inside. It's no good, a storage 
engine code that is called in between could expect a consistency - either there is a 
transaction or there is not".
Fix: move the commit to happen earlier and outside of the LOCK_open.

 - Removed the global variable(s) glob_use_running_cluster/slave
   and put a property on each "cluster" called "use_running" which
   is set to 1 if user passed either ndb_connectstring or 
   ndb_connectstring_slave. Thus mtr.pl should not start/stop the
   cluster.

only one of those is allowed

Corrected the error codes and messages for 5.1. This is to fix PB failures introduced by the patch for bug #27643.

Problem:

HASH indexes on VARCHAR columns with binary collations did not ignore trailing spaces from strings before comparisons. This could result in duplicate records being successfully inserted into a MEMORY table with unique key constraints.

As a direct consequence of the above, internal MEMORY tables used for GROUP BY calculation in testcases for bug #27643 contained duplicate rows which resulted in duplicate key errors when converting those temporary tables to MyISAM. Additionally, that error was incorrectly converted to the 'table is full' error.

Solution:

- ignore trailing spaces in VARCHAR fields with binary collations when calculating hashes.
- return a proper error from create_myisam_from_heap() when conversion fails.
