There was an erroneous parameter when calling flush_master_info
from write_ignored_events_info_to_relay_log which could lead to a
server crash. This happens because the I/O thread releases the
log_lock before calling the flush_master_info.

Set the function to call flush_master_info with third parameter
to true, so that the mutex is properly taken.

Removed --remove_file in cleanup procedure

This is a post-fix cleanup to move rpl.rpl_timezone out
of 'experimental' state.

 - Changes to the banner text
 - Use older AC_PROG_LIBTOOL (Bug#51009)

scripts/mysql_install_db.sh
 - Changes to banner text

Added --max-connections= argument to mysqltest and mtr
Small fix to first patch: forgot to check before free'ing connections array

Some logic would group by suite always
Disable this if using --noreorder
Also fix getting array from collect_one_suite() in this case
Amended according to previous comment

1. Now test use fake_relay_log primitive
2. Added RESET SLAVE to include/setup_fake_relay_log.inc for removing relay log info file
3. Added RESET SLAVE to include/cleanup_fake_relay_log.inc
4. Test moved to rpl suite as rpl_binlog_auto_inc_bug33029.test
5. Updated result file

no other functional changes.

           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.

  Added a test case for the bug#50539.

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.


mysql-test/suite/rpl/t/disabled.def:
  Got rid of the line for enabling 'rpl_cross_version' test.

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.


mysql-test/t/gis.test:
  Added test cases to verify that only geometrical
  columns can get a spatial index.
          
  In addition, verify that only a single geom.
  column can participate in a spatial index.

          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.

Add --user=root to collect_mysqld_features() if running as root
Please disregard previous commit; this is much simpler.

      
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.)

mysql-test/suite/parts/r/partition_innodb_status_file.result:
  Bug#50201: Server crashes in explain_filename on an InnoDB partitioned table
  
  New test result file
mysql-test/suite/parts/t/partition_innodb_status_file-master.opt:
  Bug#50201: Server crashes in explain_filename on an InnoDB partitioned table
  
  New test opt file
mysql-test/suite/parts/t/partition_innodb_status_file.test:
  Bug#50201: Server crashes in explain_filename on an InnoDB partitioned table
  
  New test.
  Note that the innodb monitor thread only runs every 15 seconds, so this
  test will take at least 15 seconds, so I have moved it to the parts suite.
sql/sql_table.cc:
  Bug#50201: Server crashes in explain_filename on an InnoDB partitioned table
  
  Using thd safe ER macro.
sql/unireg.h:
  Bug#50201: Server crashes in explain_filename on an InnoDB partitioned table
  
  Added ER macros for use with specified thd pointer.

Made mtr's sleep function understand $variables
A few fixes since previous patch, added tests
