do_start_slave_sql() is called from maybe_exit().
We should not recurse when maybe_exit() is called for an error during do_start_slave_sql().
Also remove a meaningless (but safe) "goto err".
- MariaDB-5.5 part of the fix: since we can't easily fix query optimization for I_S tables,
run the affected-tablespaces query with semijoin=off. It happens to have a good query plan
with that setting.

TO DUMP DATA FROM MYSQL-5.6
Analysis
--------
Dumping mysql-5.6 data using mysql-5.1/mysql-5.5 'myqldump'
utility fails with a syntax error.
Server system variable 'sql_quote_show_create' which quotes the
identifiers is set in the mysqldump utility. The mysldump utility
of mysql-5.1/mysql-5.5 uses deprecated syntax 'SET OPTION' to set
the 'sql_quote_show_create' option. The support for the syntax is
removed in mysql-5.6. Hence syntax error is reported while taking
the dump.
Fix:
---
Changed the 'mysqldump' code to use the syntax
'SET SQL_QUOTE_SHOW_CREATE' to set the 'sql_quote_show_create'
option. That syntax is supported on mysql-5.1, mysql-5.5 and
mysql-5.6.
NOTE: I have not added an mtr test case since it is difficult
to simulate the condition. Also the syntax may not be further
simplified in the future.
MYSQL DB FROM REMOTE 5.0.96 SERVER
Problem: mysqldump tool assumes the existence of
general_log and slow_log tables in the server.
If mysqldump tool executes on a old server where
there are no log tables like these, mysqldump tool
fails.
Analysis: general_log and slow_log tables are added
in the ignore-table list as part of bug-26121 fix
causes bug-45740 (MYSQLDUMP DOESN'T DUMP GENERAL_LOG
AND SLOW_QUERY CAUSES RESTORE PROBLEM). As part of
the bug-45740 fix, mysqldump tool adds create table
queries for these two tables. But the fix assumes
that on all the servers, general_log and slow_log
will be there. If the new mysqldump tool is executed
against a old server where there are no general_log
and slow_log, the mysqldump tool fails with an error
that 'there is no general_log table'.
Fix: When mysqldump tool is trying to retrieve general_log
and slow_log table structures, first the tool should
check their existence of these tables in the server
instead of trying to dump it blindly.
WITH A PORT NUMBER ENCLOSED IN QUOTES
Problem: mysqldump --dump-slave --include-master-host-port
prints the CHANGE MASTER command in the generated logical
backup. The PORT number that is generated with this command
is a string and should be an integer.
Fix: Remove the Enclosed quotes for port number.
