The MIN/MAX optimizer code from the function opt_sum_query erroneously
did not take into account conjunctive conditions that did not depend on
any table, yet were not identified as constant items. These could be
items containing rand() or PS/SP parameters. These items are supposed
to be evaluated at the execution phase. That's why if such conditions
can be extracted from the WHERE condition the MIN/MAX optimization is
not applied as currently it is always done at the optimization phase.

(In 5.3 expensive subqueries are also evaluated only at the execution
phase. So, if a constant condition with such subquery can be extracted
from the WHERE clause the MIN/MAX optimization should not be applied 
in 5.3.)

IF an IN/ALL/SOME predicate with a constant left part is transformed
into an EXISTS subquery the resulting subquery should not be considered
uncacheable if the right part of the predicate is not uncacheable.

Backported the function dbug_print_item() from 5.3. The function is used
only for debugging.  
 

- dijkstra_shortest_paths() needs a Graph as first parameter, in case of reverse_graph we now need to use
  its m_g member
- use boost::tuples::tie() on all places where tie() was used . Reason -
  fix the build with Visual Studio 10 SP1 (which includes std:tr1:tie, thus creating  ambiguity)

The function st_table::mark_virtual_columns_for_write() did not take into
account the fact that for any table the value of st_table::vfield is 0
when there are no virtual columns in the table definition.

If the sorted table belongs to a dependent subquery then the function
create_sort_index() should not clear TABLE:: select and TABLE::select
for this table after the sort of the table has been performed, because
these members are needed for the second execution of the subquery.

The range optimizer incorrectly chose a loose scan for group by
when there is a correlated WHERE condition. This range access
method cannot be executed for correlated conditions also with the
"range checked for each record" because generally the range access
method can change for each outer record. Loose scan destructively
changes the query plan and removes the GROUP operation, which will
result in wrong query plans if another range access is chosen
dynamically.

Removed previous patch of this problem.

Analysis:
The class member QUICK_GROUP_MIN_MAX_SELECT::seen_first_key
was not reset between subquery re-executions. Thus each
subsequent execution continued from the group that was
reached by the previous subquery execution. As a result
loose scan reached end of file much earlier, and returned
empty result where it shouldn't.

Solution:
Reset seen_first_key before each re-execution of the
loose scan.

After sending packet that is too large, clienrt can get either an error packet with 
ER_NET_PACKET_TOO_LARGE, or a socket error. Both cases are valid, since the
server does not ensure reply was fully read by client, before shutting down  and closing 
the socket.

  2. don't skip combinations that set --plugin-load just because the test needs another --plugin-load.
     Skip *only* if test's --plugin-load matches *exactly* --plugin-load of one of the combinations.
  3. if skipping all combinations but one, still assign the test to the combination

  Insert of checking if maria_recover_options == 0, check if any bit is set.
storage/maria/ma_check.c:
  Fixed wrong print

1. main.merge fails with errno 13 in copy_file().

The reason for the error is that copy_file tries to create a file with the same name as recently deleted one,
and there is still an open handle for the deleted file.
To fix, use my_delete_allow_opened() for MTR's delete_file. On Windows,  this renames file to unique name
prior to deletion, and prevents EACCES errors for files opened with FILE_SHARE_DELETE.

2. innodb_bug59641 
generates warnings, after server was killed and restarted in the test case.
The warnings are about test_suppression table (needs to be repaired, as it that was written just prior to the crash)
Fixed by using FLUSH TABLES after populating warning suppression table.
