Currently the Last_query_cost session status variable shows
only the cost of a single flat subselect. For complex queries
(with subselects or unions etc) Last_query_cost is not valid
as it was showing the cost for the last optimized subselect.
Fixed by reseting to zero Last_query_cost when the complete
cost of the query cannot be determined.
Last_query_cost will be non-zero only for single flat queries.

Revert the fix for bug 21587.  That bug will be re-opened, and a new
fix must be created.

Apply innodb-5.0-ss1696 snapshot

Fixes:
- Bug#20090: InnoDB: Error: trying to declare trx to enter InnoDB
- Bug#23710: crash_commit_before fails if innodb_file_per_table=1
  At InnoDB startup consider the case where log scan went beyond
  checkpoint_lsn as a crash and initiate crash recovery code path.
- Bug#28781: InnoDB increments auto-increment value incorrectly with ON DUPLICATE KEY UPDATE
  We need to do some special AUTOINC handling for the following case:
  INSERT INTO t (c1,c2) VALUES(x,y) ON DUPLICATE KEY UPDATE ...
  We need to use the AUTOINC counter that was actually used by
  MySQL in the UPDATE statement, which can be different from the
  value used in the INSERT statement.
- Bug#29097: fsp_get_available_space_in_free_extents() is capped at 4TB
  Fix by typecasting the variables before multiplying them, so that the
  result of the multiplication is of type "unsigned long long".
- Bug#29155: Innodb "Parallel recovery" is not prevented
  Fix by enabling file locking on FreeBSD.  It has been disabled because
  InnoDB has refused to start on FreeBSD & LinuxThreads, but now it
  starts just fine.

The bug caused memory corruption for some queries with top OR level
in the WHERE condition if they contained equality predicates and 
other sargable predicates in disjunctive parts of the condition.

The corruption happened because the upper bound of the memory
allocated for KEY_FIELD and SARGABLE_PARAM internal structures
containing info about potential lookup keys was calculated incorrectly
in some cases. In particular it was calculated incorrectly when the
WHERE condition was an OR formula with disjuncts being AND formulas
including equalities and other sargable predicates.

  Post fix for the bug#29948.

ORDER BY is used

The range analysis module did not correctly signal to the 
handler that a range represents a ref (EQ_RANGE flag). This causes 
non-range queries like 
SELECT ... FROM ... WHERE keypart_1=const, ..., keypart_n=const 
ORDER BY ... FOR UPDATE
to wait for a lock unneccesarily if another running transaction uses
SELECT ... FOR UPDATE on the same table.

Fixed by setting EQ_RANGE for all range accesses that represent 
an equality predicate.

The cli_read_binary_rows function is used to fetch data from the server
after a prepared statement execution. It accepts a statement handler and gets
the connection handler from it. But when the auto-reconnect option is set
the connection handler is reset to NULL after reconnection because the
prepared statement is lost and the handler became useless. This case
wasn't checked in the cli_read_binary_rows function and caused server crash.

Now the cli_read_binary_rows function checks the connection handler to be
not NULL and returns an error if it is.

The change appeared to require more changes in item_cmpfunc.cc,
which is dangerous in 5.0.

Two character mappings were way off (backtick and tilde were "E"
and "Y"!), and three others were slightly rotated.  The first 
would cause collisions, and the latter was probably benign.

Now, assign the character mappings exactly to their normal values.

MySQL replicates the time zone only when operations that involve
it are performed. This is controlled by a flag. But this flag
is set only on successful operation.
The flag must be set also when there is an error that involves
a timezone (so the master would replicate the error to the slaves). 

Fixed by moving the setting of the flag before the operation
(so it apples to errors as well).

VIEW".

mysql_list_fields() C API function would incorrectly set MYSQL_FIELD::decimals
member for some view columns.

The problem was in an incomplete implementation of 
Item_ident_for_show::make_field(), which is responsible for view
columns metadata.

a problem for BIT type values different from the one reported for the bug.
