Several problems fixed: 
  1. There was a "catch-all" context initialization in setup_tables()
    that was causing the table that we insert into to be visible in the 
    SELECT part of an INSERT .. SELECT .. statement with no tables in
    its FROM clause. This was making sure all the under-initialized
    contexts in various parts of the code are not left uninitialized.
    Fixed by removing the "catch-all" statement and initializing the 
    context in the parser.
  2. Incomplete name resolution context when resolving the right-hand
    values in the ON DUPLICATE KEY UPDATE ... part of an INSERT ... SELECT ...
    caused columns from NATURAL JOIN/JOIN USING table references in the
    FROM clause of the select to be unavailable.
    Fixed by establishing a proper name resolution context.
  3. When setting up the special name resolution context for problem 2
    there was no check for cases where an aggregate function without a
    GROUP BY effectively takes the column from the SELECT part of an 
    INSERT ... SELECT unavailable for ON DUPLICATE KEY UPDATE.
    Fixed by checking for that condition when setting up the name 
    resolution context.

  aim is to:
  a) if set_connect_timeout called, timeout connect attempt (for retry on
  next call) after timeout period
  b) preserve existing blocking behaviour otherwise (for, e.g. mgmapi)
  
  Related to customer issue with long time deleting ndb_cluster_connection
  object. believe we're hanging on the connect(2) call until timeout (when
  we then realise we should exit the thread).

    Fix bug in event handling wrt early node shutdown

- post review changes

The bug is actually a duplicate of the bug 14708.
Down-ported the fix for 14708 from 5.0.  
Merged the test case for bug 14708 from 5.0.

  Code cleanup after fix for bug#23417.

  Post fix for bug#25123.

- make sure keys are copied correctly when varchar has 2 length bytes
- test case

When inserting into a join-based view the update fields from the ON DUPLICATE
KEY UPDATE wasn't checked to be from the table being inserted into and were
silently ignored.

The new check_view_single_update() function is added to check that
insert/update fields are being from the same single table of the view.

After fix for bug#21798 JOIN stores the pointer to the buffer for sorting
fields. It is used while sorting for grouping and for ordering. If ORDER BY
clause has more elements then the GROUP BY clause then a memory overrun occurs.

Now the length of the ORDER BY list is always passed to the 
make_unireg_sortorder() function and it allocates buffer big enough to be
used for bigger list.

UNION over correlated and uncorrelated SELECTS.
In such subqueries each uncorrelated SELECT should be considered as
uncacheable. Otherwise join_free is called for it and in many cases
it causes some problems.
