when calling a SP from C API"

The bug was caused by lack of checks for misuse in mysql_real_query. 
A stored procedure always returns at least one result, which is the 
status of execution of the procedure itself.
This result, or so-called OK packet, is similar to a result
returned by INSERT/UPDATE/CREATE operations: it contains the overall
status of execution, the number of affected rows and the number of
warnings. The client test program attached to the bug did not read this 
result and ivnoked the next query. In turn, libmysql had no check for 
such scenario and mysql_real_query was simply trying to send that query 
without reading the pending response, thus messing up the communication
protocol.

The fix is to return an error from mysql_real_query when it's called
prior to retrieval of all pending results.

Fix for the bug in mysql-test-run.pl which prevents other tests succeed
after IM-test failure.
  
The idea of the fix of BUG#20716 is to:
  1. Check each SHOW INSTANCES statement, add necessary "sleep" instruction before;
  2. Move all environment checkings into the one file and include it everywhere.

           and Stored Procedure

The essence of the bug was that for every re-execution of stored
routine or prepared statement new items for character set conversions
were created, thus increasing the number of items and the time of their
processing, and creating memory leak.

No test case is provided since current test suite can't cover such type
of bugs.

           context.

Routine arguments were evaluated in the security context of the routine
itself, not in the caller's context.

The bug is fixed the following way:

  - Item_func_sp::find_and_check_access() has been split into two
    functions: Item_func_sp::find_and_check_access() itself only
    finds the function and check that the caller have EXECUTE privilege
    on it.  New function set_routine_security_ctx() changes security
    context for SUID routines and checks that definer have EXECUTE
    privilege too.

  - new function sp_head::execute_trigger() is called from
    Table_triggers_list::process_triggers() instead of
    sp_head::execute_function(), and is effectively just as the
    sp_head::execute_function() is, with all non-trigger related code
    removed, and added trigger-specific security context switch.

  - call to Item_func_sp::find_and_check_access() stays outside
    of sp_head::execute_function(), and there is a code in
    sql_parse.cc before the call to sp_head::execute_procedure() that
    checks that the caller have EXECUTE privilege, but both
    sp_head::execute_function() and sp_head::execute_procedure() call
    set_routine_security_ctx() after evaluating their parameters,
    and restore the context after the body is executed.

closing temp tables through end_thread
had a flaw in binlog-off branch of close_temporary_tables where
next table to close was reset via table->next
 for (table= thd->temporary_tables; table; table= table->next)
which was wrong since the current table instance got destoyed at
	close_temporary(table, 1);

The fix adapts binlog-on branch method to engage the loop's internal 'next' variable which holds table->next prior table's destoying.
