The task is to 
  (a) add a comment on indexes and 
  (b) increase the maximum length of column, table and the new index comments.

Removed --remove_file in cleanup procedure

WL#5154 - Remove deprecated 4.1 features

The fix is the removal of the sql_log_update_basic
test, as this option is deprecated and removed,
and a minor change to the result file of
lc_time_names_basic as the error message has
changed.

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

in 'kostja@sun.com-20091210084103-l4f8u62u4evoy3dc'.

This file is necessary for Windows builds.

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

    Multi_polygon::centroid() has an error in the implementation
      
per-file messages:
  sql/spatial.cc
Bug#38959      archive_gis fails due to rounding difference
        multi_polygon::centroid() implementation fixed

Replaced --default-character-set with --character-set-server
Replaced --language with --lc-messages-dir
NB full test suite not tested yet

WL#5154 was a task for formally deprecating and removing items that
were mentioned in the manual as having been deprecated since MySQL
4.1 or 5.0, but that had never been removed.

Since WL#5154 was created, examination of mysqld.cc, mysql.cc, and
mysqldump.c reveals additional deprecations not mentioned in the
manual. (In some cases, the items are simply not mentioned in the
5.1+ manuals.)

This is a follow-on task to deprecate and remove these additional
items.

The deprecation happened in MySQL 5.1, and the options/variables
are now removed from the code.



client/mysql.cc:
  --no-tee is now removed
client/mysqldump.c:
  --all is now removed
  -a now points to --create-options
sql/mysqld.cc:
  delay-key-write-for-all-tables is removed
  --enable-locking is removed
  --log-update is removed
  --skip-locking is removed
  --skip-symlink is removed
  --sql-bin-update-same is removed
  --warnings is removed
  --record-buffer is removed

A set of program options and variables was deprecated in
MySQL 5.1, and is hereby removed.



client/mysql.cc:
  --no-auto-rehash (-A)  is no longer deprecated
  --no-named-commands (-g) is now removed
  --skip-line-numbers (-L) is no longer deprecated
  --set-variable (-O) is now removed
  --no-pager is now removed
client/mysqlbinlog.cc:
  --position is now removed (use --start-position)
  -j is now equivalent with --start-position
client/mysqldump.c:
  --first-slave is now removed
  --no-set-names (-N) is now removed
  --set-variable (-O) is now removed
mysql-test/include/default_mysqld.cnf:
  default-character-set is removed as an option
  character-set-server is equivalent.
mysql-test/t/bug47671-master.opt:
  default-character-set option is removed
  character-set-server is equivalent
mysql-test/t/ctype_latin1_de-master.opt:
  default-character-set option is removed
  character-set-server is equivalent
mysql-test/t/ctype_ucs2_def-master.opt:
  default-collation is removed
  collation-server is equicalent
scripts/mysqld_multi.sh:
  --config-file has been superseded by
  --defaults-extra-file
sql/mysql_priv.h:
  Removed the version number in the deprecation
  warning text, as decided by ServerPT.
sql/mysqld.cc:
  --default-character-set (-C) is removed
  --default-collation is removed
  --log-long-format (-0) is removed
  --safe-show-database is removed
  --set-variable (-O) is removed
sql/sql_yacc.yy:
  The FRAC_SECOND keyword is removed
sql/sys_vars.cc:
  The sql_log_update system variable is removed

Merge mysql-trunk-bugfixing -> mysql-next-mr-bugfixing

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

Compilation failure problems on non-i386 platforms.
Adding missing parenthesis.

If a prepared statement used both a MyISAMMRG table and a stored 
function or trigger, execution could fail with "No such table"
error or crash. 
The error would come from a failure of the MyISAMMRG engine
to meet the expectations of the prelocking algorithm, 
in particular maintain lex->query_tables_own_last pointer
in sync with lex->query_tables_last pointer/the contents
of lex->query_tables. When adding merge children, the merge
engine would extend the table list. Then, when adding 
prelocked tables, the prelocking algorithm would use a pointer
to the last merge child to assign to lex->query_tables_own_last.
Then, when merge children were removed at the end of
open_tables(), lex->query_tables_own_last
was not updated, and kept pointing
to a removed merge child.

The fix ensures that query_tables_own_last is always in
sync with lex->query_tables_last.

This is a regression introduced by WL#4144 and present only
in next-4284 tree and 6.0.

mysql-test/r/merge.result:
  Update results (Bug#47648).
mysql-test/t/merge.test:
  Add a test case for Bug#47648.
  Update the result file to reflect a fix of another bug
  in MyISAMMRG code: not maintaining lex->query_tables_own_last
  allowed a stored function or trigger to modify a merge table
  which was already updated by the main statement.
  It is not allowed for other storage engines, and should
  not be allowed for MyISAMMRG.
storage/myisammrg/ha_myisammrg.cc:
  When adding children to the list of tables to open,
  make sure that we properly set lex->query_tables_own_last.
  When removing the children, update lex->query_tables_own_last
  if necessary.

MDL_lock::find_deadlock".

On some platforms deadlock detector in metadata locking 
subsystem under certain conditions might have exhausted
stack space causing server crashes.

Particularly this caused failures of rqg_mdl_stability
test on Solaris in PushBuild.

During search for deadlock MDL deadlock detector could 
sometimes encounter loop in the waiters graph in which 
MDL_context which has started search for a deadlock 
does not participate. In such case our algorithm will 
continue looping assuming that either this deadlock will 
be resolved by MDL_context which has created it (i.e.
by one of loop participants) or maximum search depth
will be reached. 
Since max search depth was set to 1000 in the latter case 
on platforms where each iteration of deadlock search 
algorithm needs more than DEFAULT_STACK_SIZE/1000 bytes 
of stack (around 192 bytes for 32-bit and around 256 bytes 
for 64-bit platforms) we might have exhausted stack space.

This patch solves this problem by reducing maximum search
depth for MDL deadlock detector to 32. This should be safe
at the moment as it is unlikely that each iteration of the 
current deadlock detector algorithm will consume more than 
1K of stack (thus total amount of stack required can't be
more than 32K) and we require at least 80K of stack in order
to open any table. Also this value should be (hopefully) big
enough to not cause too much false deadlock errors (there
is an anecdotal evidence that real-life deadlocks are
typically shorter than that).

Additional reasearch should be conducted in future in order
to determine the more optimal value of maximum search depth.

This patch does not include test case as existing
rqg_mdl_stability test can serve as one.
