Problem: binlog_stm_binlog runs INSERT DELAYED queries, and
then prints the contents of the binlog. Before checking the
contents of the binlog, the test waits until the rows have
appeared in the table. However, this is not enough, since
INSERT DELAYED does not write rows to the binlog at the same
time as it writes them to the table. So there is a race.
Fix: Add a FLUSH TABLES before SHOW BINLOG EVENTS. That
waits until the insert_delayed thread is done.

Problem: the test waits for a 'DROP TEMPORARY TABLE' event to
appear in the master's binlog, then checks on the slave whether
the number of temporary tables has decreased. The slave does
not sync, causing a race.
Fix: check for the 'DROP TEMPORARY TABLE' event on slave
instead of on master.

This is not a fix to the bug. It only adds debug info, so
that we can analyze the bug better next time it happens.
Please revert the patch after the bug is fixed.

Problem: master binlog has 'create table t1'. Master binlog
was removed before slave could replicate it. In test's cleanup
code, master did 'drop table t1', which caused slave sql
thread to stop with an error since slave sql thread did not
know about t1.
Fix: t1 is just an auxiliary construction, only needed on
master. Hence, we turn off binlogging before t1 is created,
drop t1 as soon as we don't need it anymore, and then turn
on binlogging again.

Problem: the test set @@global.init_slave to garbage at a time
which was not guaranteed to be after the time when the slave's
SQL thread used it. That would cause the slave's SQL thread to
stop in rare cases.
Fix: The test does not care about the value of
@@global.init_slave, except that it should be different on
master and slave. Hence, we set @@global.init_slave to
something that is valid SQL.

offset for time part in UUIDs was 1/1000 of what it
should be. In other words, offset was off.

Also handle the case where we count into the future
when several UUIDs are generated in one "tick", and
then the next call is late enough for us to unwind
some but not all of those borrowed ticks.

Lastly, handle the case where we keep borrowing and
borrowing until the tick-counter overflows by also
changing into a new "numberspace" by creating a new
random suffix.

2. Minor cleanup

The problem is that relying on the output of the 'ls' command is not
portable as its behavior is not the same between systems and it might
even not be available at all in (Windows).

So I added list_files that relies on the portable mysys library instead.
(and also list_files_write_file and list_files_append_file,
since the test was using '--exec ls' in that way.)

Fixed the test to expect the correct result.
The previous test script was in fact affected by 26030,
and wrongly expected a ER_PARSE_ERROR error.

problem was that ha_partition::records was not implemented, thus
using the default handler::records, which is not correct if the engine
does not support HA_STATS_RECORDS_IS_EXACT.
Solution was to implement ha_partition::records as a wrapper around
the underlying partitions records.

The rows column in explain partitions will now include the total
number of records in the partitioned table.

Before this fix, the lexer and parser would treat the ';' character as a
different token (either ';' or END_OF_INPUT), based on convoluted logic,
which failed in simple cases where a stored procedure is implemented as a
single statement, and used in a multi query.

With this fix:
- the character ';' is always parsed as a ';' token in the lexer,
- parsing multi queries is implemented in the parser, in the 'query:' rules,
- the value of thd->client_capabilities, which is the capabilities
  negotiated between the client and the server during bootstrap,
  is immutable and not arbitrarily modified during parsing (which was the
  root cause of the bug)

 - moved the test into a separate file to check for presence of the test variable

On certain kinds of errors (e.g., out of stack), a call to Item_func_
set_user_var::fix_fields() might fail.  Since the return value of this
call was not checked inside User_var_log_event::exec_event(), continuing
execution after this will cause a crash inside Item_func_set_user_var::
update_hash().

The bug is fixed by aborting execution of the event with an error if
fix_fields() fails, since it is not possible to continue execution anyway.
