Bug #22540: Incorrect value in column End_log_pos of SHOW BINLOG EVENTS using InnoDB
fix binlog-writing so that end_log_pos is given correctly even
within transactions for both SHOW BINLOG and SHOW MASTER STATUS,
that is as absolute values (from log start) rather than relative
values (from transaction's start).

Bug#22540: Incorrect value in column End_log_pos of SHOW BINLOG EVENTS using InnoDB
end_log_pos data within a transaction are relative to
the start of the transaction rather than absolute.
we fix those groups in situ before writing the log out.
additional comments and handling for groups with very
large single events, as suggested by Guilhem.

the loose scan optimization for grouping queries was applied returned
a wrong result set when the query was used with the SQL_BIG_RESULT
option.
The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
queries instead of employing a suitable index. The current loose scan
optimization is applied only for one table queries when the suitable
index is covering. It does not make sense to use sort algorithm in this
case. However the create_sort_index function does not take into account
the possible choice of the loose scan to implement the DISTINCT operator
which makes sorting unnecessary. Moreover the current implementation of
the loose scan for queries with distinct assumes that sorting will
never happen. Thus in this case create_sort_index should not call
the function filesort.
INSERT into table from SELECT from the same table
with ORDER BY and LIMIT was inserting other data
than sole SELECT ... ORDER BY ... LIMIT returns.
One part of the patch for bug #9676 improperly pushed
LIMIT to temporary table in the presence of the ORDER BY
clause.
That part has been removed.
The reason the "reap;" succeeds unexpectedly is because the query was completing(almost always) and the network buffer was big enough to store the query result (sometimes) on Windows, meaning the response was completely sent before the server thread could be killed.
Therefore we use a much longer running query that doesn't have a chance to fully complete before the reap happens, testing the kill properly.
- When creating an index for the sort, the number of rows plus 1 is used
to allocate a buffer. In this test case, the number of rows 4294967295
is the max value of an unsigned integer, so when 1 was added to it, a
buffer of size 0 was allocated causing the crash.
- Create new test suite for this bug's test suite as per QA.
