NULLable BIGINT and INT columns in comparison

Problem: a consequence of the fix for 43668.
Some Arg_comparator inner initialization missed,
that may lead to unpredictable (wrong) comparison
results.

Fix: always properly initialize Arg_comparator
before its usage.

The bug 38816 changed the lock that protects THD::query from
LOCK_thread_count to LOCK_thd_data, but didn't update the associated
InnoDB functions.

1. The innobase_mysql_prepare_print_arbitrary_thd and the
innobase_mysql_end_print_arbitrary_thd InnoDB functions have been
removed, since now we have a per-thread mutex: now we don't need to wrap
several inter-thread access tries to THD::query with a single global
LOCK_thread_count lock, so we can simplify the code.

2. The innobase_mysql_print_thd function has been modified to lock
LOCK_thd_data in direct way.

  branches/5.1: fix bug#3139: Mysql crashes: 'windows error 995'
  after several selects on a large DB
  
  During stress environment, Windows AIO may fail with error code
  ERROR_OPERATION_ABORTED. InnoDB does not handle the error, rather
  crashes. The cause of the error is unknown, but likely due to
  faulty hardware or driver.
  
  This patch introduces a new error code OS_FILE_OPERATION_ABORTED,
  which maps to Windows ERROR_OPERATION_ABORTED (995). When the error
  is detected during AIO, the InnoDB will issue a synchronous retry
  (read/write).
  
  This patch has been extensively tested by MySQL support.

    message:
      BUG#42829: binlogging enabled for all schemas regardless of
      binlog-db-db / binlog-ignore-db
            
      InnoDB will return an error if statement based replication is used
      along with transaction isolation level READ-COMMITTED (or weaker),
      even if the statement in question is filtered out according to the
      binlog-do-db rules set. In this case, an error should not be printed.
            
      This patch addresses this issue by extending the existing check in
      external_lock to take into account the filter rules before deciding to
      print an error. Furthermore, it also changes decide_logging_format to
      take into consideration whether the statement is filtered out from 
      binlog before decision is made.

branches/zip: Free all resources at shutdown. Set pointers to NULL, so
that Valgrind will not complain about freed data structures that are
reachable via pointers.  This addresses Bug #45992 and Bug #46656.

This patch is mostly based on changes copied from branches/embedded-1.0,
mainly c5432, c3439, c3134, c2994, c2978, but also some other code was
copied.  Some added cleanup code is specific to MySQL/InnoDB.

SET TRANSACTION ISOLATION LEVEL is used to temporarily set
the trans.iso.level for the next transaction.  After the
transaction, the iso.level is (re-)set to value of the 
session variable 'tx_isolation'.

The bug is caused by setting the thd->variables.tx_isolation 
field to the value of the session variable upon each
statement commit.  It should only be set at the end of the
full transaction.

The fix has been to remove the setting of the variable in
ha_autocommit_or_rollback if we're in a transaction, as it 
will be correctly set in  either ha_rollback or 
ha_commit_one_phase.  

If, on the other hand, we're in  autocommit mode, tx_isolation 
will be explicitly set here.



mysql-test/t/innodb_mysql.test:
  "SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED" sets
  the trans.isolation for the next transaction.  We test
  that @@tx_isolation keeps this value during the transaction,
  and is only reset back to the session value at the end
  of the transaction.

1. Enabling the disabled test for BUG#32430 for builtin innodb
2. Disabling the innodb-autoinc.test for innodb plugin.

1. BUG#47720 - REPLACE INTO Autoincrement column with negative values.

branches/5.1: Fix Bug#47720 - REPLACE INTO Autoincrement column with negative values.

This bug is similiar to the negative autoinc filter patch from earlier,
with the additional handling of filtering out the negative column values
set explicitly by the user.
