Bug #11766501: Multiple RBS break the get rseg with mininum trx_t::no code during purge
      
Bug# 59291 changes:
      
Main problem is that truncating the UNDO log at the completion of every
trx_purge() call is expensive as the number of rollback segments is increased.
We truncate after a configurable amount of pages. The innodb_purge_batch_size
parameter is used to control when InnoDB does the actual truncate. The truncate
is done once after 128 (or TRX_SYS_N_RSEGS iterations). In other words we
truncate after purge 128 * innodb_purge_batch_size. The smaller the batch
size the quicker we truncate.
      
Introduce a new parameter that allows how many rollback segments to use for
storing REDO information. This is really step 1 in allowing complete control
to the user over rollback space management.
      
New parameters:
    i) innodb_rollback_segments = number of rollback_segments to use
       (default is now 128) dynamic parameter, can be changed anytime.
       Currently there is little benefit in changing it from the default.
      
Optimisations in the patch.
      
    i. Change the O(n) behaviour of trx_rseg_get_on_id() to O(log n)
       Backported from 5.6. Refactor some of the binary heap code.
       Create a new include/ut0bh.ic file.
      
    ii. Avoid truncating the rollback segments after every purge.
      
Related changes that were moved to a separate patch:
      
    i. Purge should not do any flushing, only wait for space to be free so that
       it only does purging of records unless it is held up by a long running
       transaction that is preventing it from progressing.
      
   ii. Give the purge thread preference over transactions when acquiring the
       rseg->mutex during commit. This to avoid purge blocking unnecessarily
       when getting the next rollback segment to purge.
      
Bug #11766501 changes:
      
Add the rseg to the min binary heap under the cover of the kernel mutex and
the binary heap mutex. This ensures the ordering of the min binary heap.
      
The two changes have to be committed together because they share the same
that fixes both issues.

              UPDATES THE TABLE ENTRIES (formerly 55385)
BUG#11764529: MULTI UPDATE+INNODB REPORTS ER_KEY_NOT_FOUND 
              IF A TABLE IS UPDATED TWICE (formerly 57373)
            
If multiple-table update updates a row through two aliases and
the first update physically moves the row, the second update will
fail to locate the row. This results in different errors
depending on storage engine:
  * MyISAM: Got error 134 from storage engine
  * InnoDB: Can't find record in 'tbl'
None of these errors accurately describe the problem. 
      
Furthermore, since MyISAM is non-transactional, the update
executed first will be performed while the second will not.
In addition, for two equal multiple-table update statements,
one could succeed and the other fail based on whether or not
the record actually moved or not. This was inconsistent.
      
Two update operations may physically move a row:
  1) Update of a column in a clustered primary key
  2) Update of a column used to calculate which partition the 
     row belongs to
           
BUG#11764529 is about case 1) above, BUG#11762751 was about case 2).
      
The fix for these bugs is to return with an error if multiple-table 
update is about to:
  a) Update a table through multiple aliases, and
  b) Perform an update that may physically more the row 
     in at least one of these aliases
    
This avoids 
  * partial updates as described for MyISAM above,
  * provides the same error message that describes the actual problem
    for all SEs
  * inconsistent behavior where a statement fails or succeeds based on
    e.g. the partitioning algorithm of the table.

Will do so unless tests/suited named on mtr command line
Also add option to turn on/off
Will be made to look like a test 'unit-test' which counts towards total

The problem was that doing ALTER TABLE on a table which had a key
on a TEXT/BLOB column with a prefix longer than the maximum number
of characteres in this column (as per the character set), by mistake,
caused an error (Error 1170 - ER_BLOB_KEY_WITHOUT_LENGTH).

This bug not repeatable in 5.5.

This patch adds a regression test to alter_table.test and
contains no code changes.

Remove last traces of HAVE_NDBCLUSTER_DB define - it has not had an effect in a long time and is just confusing.
At the same time backport the removal of OPT_NDB_CONNECTSTRING and OPT_NDBCLUSTER values from "enum options_client"

               ("-") IN DATABASE NAMES IN ALTER DATABASE.

mysqldump did not quote database name in 'ALTER DATABASE'
statements in its output. This can further cause a failure
while loading if database name contains a hyphen '-'.

This happened as, while printing the 'ALTER DATABASE'
statements, the database name was not quoted.

Fixed by quoting the database name.

  Bug#11766310 : 59398: MYSQLDUMP 5.1 CAN'T HANDLE A DASH
                 ("-") IN DATABASE NAMES IN ALTER DATABASE.
  
  Modified the print statement in order to print the quoted
  database name for 'ALTER DATABASE' statements.
mysql-test/r/mysqldump.result:
  Added a test case for bug#11766310.
mysql-test/t/mysqldump.test:
  Added a test case for bug#11766310.

A separate fix for 5.1 (as 5.1 and 5.5 have seriously
differged in the related pieces of the code).
A patch for 5.5 was approved earlier.

Problem: ucs2 was correctly disallowed in "SET NAMES" only,
while mysql_real_connect() and mysql_change_user() still allowed
to use ucs2, which made server crash.

Fix: disallow ucs2 in mysql_real_connect() and mysql_change_user().
