no ORDER BY in views

[Federico Razzoli]

Reasons to avoid ORDER BY in views:
* There is a regression bug in My 5.5/5.6: http://bugs.mysql.com/bug.php?id=69678 Will it regress again? Does Oracle create (and execute) regression bugs? No one knows, I think.
* ORDER BYs in views are somewhat anti-relational, because entities don't have an order.
* information_schema virtual tables dont have an order, even when a natural order is possible (ie SCHEMATA)

However, views with ORDER BY are tester-friendly, so:
* the original view should remain, but without ORDER BY
* a stored procedure which returns an ordered resultset must be added

The following views have an ORDER BY and the following sp must be added:
* last_test_results - show_last_results()
* last_test_results_bad - show_last_bad_results()
* recent_test_results - show_results()
* recent_test_results_bad - show_bad_results()
* my_dbug_log - show_dbug_log()

(however stk/dbug will be used in 2.0, hopefully)
