Support for flushing individual logs, so that the user can
selectively flush a subset of the server logs.

Flush of individual logs is done according to the 
following syntax:

  FLUSH <log_category> LOGS;

The syntax is extended so that the user is able to flush a
subset of logs:

  FLUSH [log_category LOGS,];

where log_category is one of:
  SLOW
  ERROR
  BINARY
  ENGINE
  GENERAL
  RELAY.


mysql-test/suite/rpl/r/rpl_flush_logs.result:
  Test result for WL#5142.
mysql-test/suite/rpl/t/rpl_flush_logs.test:
  Added the test file to verify if the 'flush individual log' 
  statement works fine.
sql/log.cc:
  Added the two functions to flush slow and general log.
sql/sql_parse.cc:
  Added code to flush specified logs against the option.
sql/sql_yacc.yy:
  Added code to parse the 'flush * log' statement syntax and 
  set its option to Lex->type.

merging from 5.1 to rep+2 starting at gca(5.1, next-mr) == build@mysql.com-20091104182209-iui387z35159aoyw

NOTE: backporting BUG#42150 into next-mr
      Includes latest Andrei's patch (see [2 Feb 18:40] Bugs System)
      and merge.test post-push fix (see [3 Feb 18:04] Bugs System)

The reason of the bug appeared to be overreacting on absense of a
binlog file although the file name had been presented in in the master
binlog index file.
By convention, there should have been only a warning printed and the rest of
`reset master' logics completed.  This did not happen on windows
due to incorrect value of my_errno returned from nt_share_delete().
      
Fixed with correcting my_errno assignment in nt_share_delete() to be ENOENT in 
he event of no binlog file. Some minor refactoring has been made.

beyond unsigned long.
BUG#44779: binlog.binlog_max_extension may be causing failure on 
next test in PB
            
NOTE1: this is the backport to next-mr.
NOTE2: already includes patch for BUG#44779.
            
Binlog file extensions would turn into negative numbers once the
variable used to hold the value reached maximum for signed
long. Consequently, incrementing value to the next (negative) number
would lead to .000000 extension, causing the server to fail.
                        
This patch addresses this issue by not allowing negative extensions
and by returning an error on find_uniq_filename, when the limit is
reached. Additionally, warnings are printed to the error log when the
limit is approaching. FLUSH LOGS will also report warnings to the
user, if the extension number has reached the limit. The limit has been
set to 0x7FFFFFFF as the maximum.

mysql-test/suite/binlog/t/binlog_max_extension.test:
  Test case added that checks the maximum available number for
  binlog extensions.
sql/log.cc:
  Changes to find_uniq_filename and test_if_number.
sql/log.h:
  Added macros with values for MAX_LOG_UNIQUE_FN_EXT and
  LOG_WARN_UNIQUE_FN_EXT_LEFT, as suggested in review.

The mentioned on the bug report set of bugs fixes have not be pushed to the main trees.

Fixed with extracting commits done to 6.0-rpl tree and applying them to the main 5.1.
Notes.
1. part of changes - the mtr's specific - were packported to the main 5.0 tree for mtr v1
   as http://lists.mysql.com/commits/46562
   However, there is no that fix anymore in the mtr v2. (This fact was mailed to mtr maintaining
   people).

2. Bug@36929  crash in kill_zombie_dump_threads-> THD::awake() with replication tests
   is not backported because the base code of the patch is libevent and that was removed
   from the main trees due to its instability.

Post-push fix: Removed MTRv1 arguments according to the
original patch. Although there is a version check, the patch
was pushed to a 5.1 GA staging tree, while the version check 
considers version 5.2. This makes the deprecated parameters 
to be used, despite the fact that they are not valid anymore.

Part of MTRv1 is currently used in RQG semisync test, and this
was causing the test to fail on slave startup.

It should be safe to uncomment when merging up to celosia.

Post-push fix: Reverting change in Makefile.am which was
causing windows not to build client/.

One statement that have more than one different tables to update with 
autoinc columns just was marked as unsafe in mixed mode, so the unsafe 
warning can't be produced in statement mode.

  Reomved the 'set_current_stmt_binlog_row_based_if_mixed' function 
  for producing unsafe warnings by executing 'decide_logging_format' 
  function later in statement mode

Removed test case that was left without significance after
backporting the deprecated constructs from 6.0 codebase.

Bug#41756 "Strange error messages about locks from InnoDB".
      
In JT_EQ_REF (join_read_key()) access method, 
don't try to unlock rows in the handler, unless certain that 
a) they were locked
b) they are not used.

Unlocking of rows is done by the logic of the nested join loop,
and is unaware of the possible caching that the access method may
have. This could lead to double unlocking, when a row
was unlocked first after reading into the cache, and then 
when taken from cache, as well as to unlocking of rows which
were actually used (but taken from cache).
      
Delegate part of the unlocking logic to the access method,
and in JT_EQ_REF count how many times a record was actually 
used in the join. Unlock it only if it's usage count is 0.

            values return too many records

WHERE clauses with "outer_value_list NOT IN subselect" were
handled incorrectly if the outer value list contained multiple 
items where at least one of these could be NULL. The first 
outer record with NULL value was handled correctly, but if a 
second record with NULL value existed, the optimizer would 
choose to reuse the result it got on the last execution of the 
subselect. This is incorrect if the outer value list has 
multiple items.
     
The fix is to make Item_in_optimizer::val_int (in 
item_cmpfunc.cc) reuse the result of the latest execution
for NULL values only if all values in the outer_value_list 
are NULL.

branches/zip: This test has been problematic for sometime now. The underlying
bug is that the data dictionaries get out of sync. In the AUTOINC code we
try and apply salve to the symptoms. In the past MySQL made some unrelated
change and the dictionaries stopped getting out of sync and this test started
to fail. Now, it seems they have reverted that changed and the test is
passing again. I suspect this is not he last time that this test will change.

branches/zip: Fix corruption of buf_pool->LRU_old and improve debug assertions.
This was reported as Issue #381.

buf_page_set_old(): Assert that blocks may only be set old if
buf_pool->LRU_old is initialized and buf_pool->LRU_old_len is nonzero.
Assert that buf_pool->LRU_old points to the block at the old/new boundary.

buf_LRU_old_adjust_len(): Invoke buf_page_set_old() after adjusting
buf_pool->LRU_old and buf_pool->LRU_old_len, in order not to violate
the added assertions.

buf_LRU_old_init(): Replace buf_page_set_old() with a direct
assignment to bpage->old, because these loops that initialize all the
blocks would temporarily violate the assertions about
buf_pool->LRU_old.

buf_LRU_remove_block(): When setting buf_pool->LRU_old = NULL, also
clear all bpage->old flags and set buf_pool->LRU_old_len = 0.

buf_LRU_add_block_to_end_low(), buf_LRU_add_block_low(): Move the
buf_page_set_old() call later in order not to violate the debug
assertions.  If buf_pool->LRU_old is NULL, set old=FALSE.

buf_LRU_free_block(): Replace the UNIV_LRU_DEBUG assertion with a
dummy buf_page_set_old() call that performs more thorough checks.

buf_LRU_validate(): Do not tolerate garbage in buf_pool->LRU_old_len
even if buf_pool->LRU_old is NULL.  Check that bpage->old is monotonic.

buf_relocate(): Make the UNIV_LRU_DEBUG checks stricter.

buf0buf.h: Revise the documentation of buf_page_t::old and
buf_pool_t::LRU_old_len.
