  Fix error in previous push

  Fix bug: InnoDB could print that it cannot find a clustered index record if an update undo, purge, and a consistent read coincided, in rare cases it might also have returned a wrong row in a query

Test fix (this sync_with_master was nonsense).
Now all tests pass in 4.0 in autobuild.

More messages.
Testcase for bug 651.

  Cleanup
ha_innodb.cc, data0type.h:
  Make sure non-latin1 users can downgrade from 4.0.14 to an earlier version if they have not created DATA_BLOB column prefix indexes

  Cleanup; remove compiler warning on Windows

thd->enter_cond() and exit_cond(), so that the I/O thread accepts to stop
when it's waiting for relay log space.
Reset ignore_log_space_limit to 0 when the SQL thread terminates.

  Merge InnoDB-4.0.14: SAVEPOINT now implemented; InnoDB now accepts also column prefix keys; crashing bug in ON UPDATE CASCADE fixed; page checksum formula fixed

Could not add a testcase for this: if the test goes into a MASTER_POS_WAIT, it waits
until this terminates (even doing "connection other_con" to launch "stop slave" is blocked).
- In MASTER_POS_WAIT() don't test if the I/O slave is running, but if the SQL thread
is running.
- Some DBUG info for this bugfix.

if one is running many mysqlds through mysqld_multi, for example.
Without this option, on Linux one mysqld_safe process may kill
other mysqlds as well, if started using the same binary and path.

 - Added missing function name in checking for sem_init in posix4 libs on

Item_extract needs special implementation for eq().

Item_extract::int_type parameters also

support issue with an unclear message which can have N reasons for appearing.
This should help us know at which point it failed, and get the errno when
my_open was involved (as the reason for the unclear message is often a
permission problem).
RESET SLAVE resets last_error and last_errno in SHOW SLAVE STATUS (without this,
rpl_loaddata.test, which is expected to generate an error in last_error, influenced
rpl_log_pos.test).
A small test update.
Added STOP SLAVE to mysql-test-run to get rid of several stupid error messages
which are printed while the master restarts and the slave attempts/manages to
connect to it and sends it nonsense binlog requests.

Added option --gdb

we now make a distinction between if the master is < 3.23.57, 3.23 && >=57, and 4.x
(before the 2 3.23 were one). This is because in 3.23.57 we have a way to distinguish between
a Start_log_event written at server startup and one written at FLUSH LOGS, so we
have a way to know if the slave must drop old temp tables or not.
Change: mi->old_format was bool, now it's enum (to handle 3 cases). However, functions
which had 'bool old_format' as an argument have their prototypes unchanged, because
the old old_format == 0 now corresponds to the enum value BINLOG_FORMAT_CURRENT which
is equal to 0, so boolean tests are left untouched. The only case were we use mi->old_format
as an enum instead of casting it implicitly to a bool, is in Start_log_event::exec_event,
where we want to distinguish between the 3 possible enum values.

  Add syntax SAVEPOINT id and ROLLBACK TO SAVEPOINT id. This is compatible with DB2 and Oracle but not with SQL Server. Savepoints do not do anything yet, this is just parsing.
