Merging the fix from mysql-5.1 to mysql-5.5

mysql-test/t/mysqldump.test:
  There is a difference in the testcase which is added as 
  part of this fix, when compared with mysql-5.1. In mysql-5.5 
  and mysql-5.6, "DROP mysql database" fails by enabling 
  logging, hence removed those lines.

                     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.

client/mysqldump.c:
  In get_table_structure() added code to skip the DROP TABLE stmts for general_log
  and slow_log tables, because when logging is enabled those stmts will fail. And
  replaced CREATE TABLE with CREATE IF NOT EXISTS for those tables, just to make 
  sure CREATE stmt for those tables doesn't fail since we removed DROP stmts for
  those tables.
  In dump_all_tables_in_db() added code to call get_table_structure() for 
  general_log and slow_log tables.

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".

Fixed not to check timeout during the check table.

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.

The function mysql_show_binlog_events has a local stack variable
'LOG_INFO linfo;', which is assigned to thd->current_linfo, however
this variable goes out of scope and is destroyed before clean
thd->current_linfo.

The problem is solved by moving 'LOG_INFO linfo;' to function scope.

BUG#11761686 insert_id event is not filtered.
  
Two issues are covered.
  
INSERT into autoincrement field which is not the first part in the composed primary key 
is unsafe by autoincrement logging design. The case is specific to MyISAM engine
because Innodb does not allow such table definition.
  
However no warnings and row-format logging in the MIXED mode was done, and
that is fixed.
  
Int-, Rand-, User-var log-events were not filtered along with their parent
query that made possible them to screw up execution context of the following
query.
  
Fixed with deferring their execution until the parent query.

Details:
- Merge : 5.1 -> 5.5
- Addded a new test case which was not added in 5.1 because PS was
  not there in 5.1.

Reason:
 This is a regression happened because of changes done in code refactoring 
 in 5.1 from 5.0.

Issue: 
 While doing "Show tables" lex->verbose was being checked to avoid opening
 FRM files to get table type. In case of "Show full table", lex->verbose
 is true to indicate table type is required. In 5.0, this check was
 present which got missing in >=5.5.

Fix:
 Added the required check to avoid opening FRM files unnecessarily in case
 of "Show tables".

Stored program cache produces wrong result in same THD.

confusing error. Updated the test script to work properly on
windows platform.
