Applied the fix that updates yaSSL to 2.2.1 and fixes parsing this 
particular certificate.
Added a test case with the certificate itself.

BY A CONCURRENT TRANSACTIO

The member function QUICK_RANGE_SELECT::init_ror_merged_scan() performs
a table handler clone. Innodb does not provide a clone operation.  
The ha_innobase::clone() is not there. The handler::clone() does not 
take care of the ha_innobase->prebuilt->select_lock_type.  Because of 
this what happens is that for one index we do a locking read, and 
for the other index we were doing a non-locking (consistent) read. 
The patch introduces ha_innobase::clone() member function.  
It is implemented similar to ha_myisam::clone().  It calls the 
base class handler::clone() and then does any additional operation 
required.  I am setting the ha_innobase->prebuilt->select_lock_type 
correctly.

                     CAUSES RESTORE PROBLEM

Merging the fix from mysql-5.1 to mysql-5.5

                     CAUSES RESTORE PROBLEM
Problem Statement:
------------------
mysqldump is not having the dump stmts for general_log and slow_log
tables. That is because of the fix for Bug#26121. Hence, after 
dropping the mysql database, and applying the dump by enabling the 
logging, "'general_log' table not found" errors are logged into the 
server log file.

Analysis:
---------
As part of the fix for Bug#26121, we skipped the dumping of tables 
for general_log and slow_log, because the data dump of those tables 
are taking LOCKS, which is not allowed for log tables.

Fix:
----
We came up with an approach that instead of taking both meta data 
and data dump information for those tables, take only the meta data 
dump which doesn't need LOCKS.
As part of fixing the issue we came up with below algorithm.
Design before fix:
1) mysql database is having tables like db, event,... general_log,
   ... slow_log...
2) Skip general_log and slow_log while preparing the tables list
3) Take the TL_READ lock on tables which are present in the table 
   list and do 'show create table'.
4) Release the lock.

Design with the fix:
1) mysql database is having tables like db, event,... general_log,
   ... slow_log...
2) Skip general_log and slow_log while preparing the tables list
3) Explicitly call the 'show create table' for general_log and 
   slow_log
3) Take the TL_READ lock on tables which are present in the table 
   list and do 'show create table'.
4) Release the lock.

While taking the meta data dump for general_log and slow_log the 
"CREATE TABLE" is replaced with "CREATE TABLE IF NOT EXISTS". 
This is because we skipped "DROP TABLE" for those tables, 
"DROP TABLE" fails for these tables if logging is enabled. 
Customer is applying the dump by enabling logging so, if the dump 
has "DROP TABLE" it will fail. Hence, removed the "DROP TABLE" 
stmts for those tables.
  
After the fix we could observe "Table 'mysql.general_log' 
doesn't exist" errors initially that is because in the customer 
scenario they are dropping the mysql database by enabling the 
logging, Hence, those errors are expected. Once we apply the 
dump which is taken before the "drop database mysql", the errors 
will not be there.

TO "LOCALHOST" IF LOCALHOST IS BOTH IPV4/IPV6 ENABLED.

Previous commit comments were wrong. The default value has always been NULL.
The original patch for Bug#12762885 just makes it visible in the logs.

This patch uses "0.0.0.0" string if bind-address is not set.

IF LOCALHOST IS BOTH IPV4/IPV6 ENABLED.

The original patch removed default value of the bind-address option.
So, the default value became NULL. By coincedence NULL resolves
to 0.0.0.0 and ::, and since the server chooses first IPv4-address, 
0.0.0.0 is choosen. So, there was no change in the behaviour.

This patch restores default value of the bind-address option to "0.0.0.0".

Problem - The failure on PB2 is possbily due to the port number being still in
          use even after the server restarts which is not reflected in the
          server restart.
      
Fix - The problem is fixed by starting the servers forcefully using the option
      file and also the parameters for the server restart is passed correctly.

Check return value from os_aio_init() and refuse to start if it fails.

rpl_auto_increment_bug45679.test is refined due to not fixed in 5.1 Bug11749859-39934.

Details:
 - test case bug12427262.test was failing on windows because
   on windows '/' was not recognized. And this was used in
   LIKE clause of the query being run in this test case.

Fix:
 - Windows needs '\\\\' for path seperater in mysql. I was 
   not sure how to keep a single query with two different 
   syntax based on platform. So modifying query to make sure
   it runs correctly on both platform.

Merge from 5.1 into 5.5.
