(because it's conceptually wrong. only the user can decide whether the kill is
allowed to leave tables in the inconsistent state, storage engine has no say in that)

DIAGNOSTICS_AREA::SET_OK_STATUS
Use DBUG_RETURN() instead of return() if DBUG_ENTER() is
used in the function. This patch is to fix the Windows
pb2 failure on mysql-5.1
Approved by Marko. rb#1792
DIAGNOSTICS_AREA::SET_OK_STATUS
Test fails on 5.1 valgrind build. This is because of close(-1)
system call.
Fixed by adding extra checks for valid file descriptor.
Approved by Vasil(Calvin). rb#1792
Before this fix, configuring the server with:
- performance_schema_events_waits_history_size=0
- performance_schema_events_waits_history_long_size=0
could cause a crash in the performance schema.
These settings to 0 are intended to be valid and supported,
and are in fact working properly in mysql 5.6 and up already.
This fix backports the code fix and test cases from mysql 5.6
to the mysql 5.5 release.
ON "DROP TABLE"
In the function ha_archive::write_row(), there is an error code path
that exits the function without releasing the mutex that was acquired
earlier.

HANG
Problem Statement:
When the operation RENAME TABLE is about rename the tablespace of the
table, it will stop all i/o operations on the tablespace temporarily.
For this the fil_space_t::stop_ios member is used.
Once the fil_space_t::stop_ios member is set to TRUE in the RENAME
TABLE operation, it is expected that no new i/o operation will be done
on the tablespace and all pending i/o operation can be completed on
the tablespace.
If the pending i/o operations initiate any new i/o operations then
there will be deadlock. The RENAME TABLE operation will be waiting
for pending i/o on the tablespace to be completed, and the pending i/o
operations will be waiting on the RENAME TABLE operation to set the
file_space_t::stop_ios flag to be set to FALSE.
But in the given scenario the pending i/o operations did not initiate
new i/o. But they where still unnecessarily checking the
fil_space_t::stop_ios flag. This resulted in deadlock.
Solution:
I noticed that this deadlock happens in fil_space_get_size() and
fil_space_get_zip_size() in the i/o threads. These functions check
the stop_ios flag even when no i/o will be initiated. I modified
these functions to ensure that they check the stop_ios flag only when
they will be initiating an i/o operation. This solves the problem.

In innobase_mysql_tmpfile(): allocate/open the file after
the return(-1); statement.
SAME VERSION NUMBER 1.0.17
Now that InnoDB/InnoDB Plugin is no longer separately developed and
distributed from the MySQL server it does not need its own version number.
Thus use the MySQL version instead.
"Removing" the version altogether is not feasible because the config
variable 'innodb_version' cannot be removed in GA branches.
