           function with distinct.
Loose index scan is used to find MIN/MAX values using appropriate index and
thus allow to avoid grouping. For each found row it updates non-aggregated
fields with values from row with found MIN/MAX value.
Without loose index scan non-aggregated fields are copied by end_send_group
function. With loose index scan there is no need in end_send_group and
end_send is used instead. Non-aggregated fields still need to be copied and
this was wrongly implemented in QUICK_GROUP_MIN_MAX_SELECT::get_next.
WL#3220 added a case when loose index scan can be used with end_send_group to
optimize calculation of aggregate functions with distinct. In this case
the row found by QUICK_GROUP_MIN_MAX_SELECT::get_next might belong to a next
group and copying it will produce wrong result.

Update of non-aggregated fields is moved to the end_send function from
QUICK_GROUP_MIN_MAX_SELECT::get_next.

The MDL_SHARED lock was introduced for an object in 5.4, but the 'TABLE_LIST' 
object was not initialized with the MDL_SHARED lock when applying event with 
LOAD DATA INFILE into table. So the failure is caused when checking the 
MDL_SHARED lock for the object.
To fix the problem, the 'TABLE_LIST' object was initialized with the MDL_SHARED 
lock when applying event with LOAD DATA INFILE into table.

this includes a major whitespace (formatting) alignment
and sequence changes to better agree with other spec files.

Further changes:
- All features are controlled by "%define" set from call
  options or builtin.
- "bundled zlib" is on by default.
- "with libgcc" is controlled by runtime detection of gcc.
- Handling of "CFLAGS" and "CXXFLAGS" is more concentrated.
- Several missing man pages were added.

          causing crashes!

Adding a SPATIAL INDEX on a non-geometrical column caused a
segmentation fault when the table was subsequently 
inserted into.
      
A test was added in mysql_prepare_create_table to explicitly
check whether non-geometrical columns are used in a
spatial index, and throw an error if so.

          corruption and crash results
      
An index creation statement where the index key
is larger/wider than the column it references 
should throw an error.
      
A statement like:
  CREATE TABLE t1 (a CHAR(1), PRIMARY KEY (A(255)))
did not error, but a segmentation fault followed when
an insertion was attempted on the table
      
The partial key validiation clause has been 
restructured to (hopefully) better document which
uses of partial keys are valid.

      
We found that there are some tests that are not cleaning
up properly:
      
  1. rpl_tmp_table_and_DDL
  2. rpl_do_grant
  3. rpl_sync
      
For #1 and #2 we found that the slave would not, for some
cases, replicate all the instructions the master processed 
in the cleanup section. We fix these by deploying some 
synchronization commands in the test cases so that slave 
processes all clean up instructions.
      
As for #3, this is tracked as part of another bug 
(BUG@50442).

Problem was that in mysql-trunk the ER() macro is now dependent on current_thd
and the innodb monitor thread has no binding to that thd object. This cause 
the crash because of bad derefencing.

Solution was to add a new macro which take the thd as an argument (which the innodb
thread uses for the call).

(Updated according to reviewers comments, i.e. added ER_THD_OR_DEFAULT and
moved test to suite parts.)

The number for MYSQL_REPLICATION_PLUGIN was shifted when backporting
because MYSQL_AUDIT_PLUGIN was not backported.

This problem is fixed by backporting only the number of audit plugin
and print an error when trying to load audit plugins. Note that
replication plugins compiled against old MYSQL_REPLICATION_PLUGIN
number will also be recognized as audit plugin and be rejected.

The IO thread can concurrently access the relay log IO_CACHE
while another thread is performing an FLUSH LOGS procedure.
      
FLUSH LOGS closes and reopens the relay log and while doing so it
(re)initializes its IO_CACHE. During this procedure the IO_CACHE
mutex is also reinitialized, which can cause problems if some
other thread (namely the IO THREAD) is concurrently accessing it
at the time .
      
This patch fixes the problem by extending the interface of the
flush_master_info function to also include a second paramater, 
"need_relay_log_lock", stating whether the thread should grab the 
relay log lock or not before actually flushing the relay log. 
Also, IO thread now calls flush_master_info with this flag set 
when it flushes master info with in the event read_event loop.

Finally, we also increase loop time in rpl_heartbeat_basic test 
case, so that the number of calls to flush logs doubles, stressing
this part of the code a little more.

To be able to specify the use of USTAR when creating the source
TAR, we needed both to update the GNU autotools version requirements
slightly, and update the initiation of the tools to use more
modern constructs.

Get rid of trailing blanks.
