In the ha_partition::position() we don't calculate the number
of the partition of the record, but use m_last_part value instead,
relying on that it's previously set by some other call like ::write_row().
Delete_rows_log_event::do_exec_row() calls find_and_fetch_row(),
where we used position() + rnd_pos() call for the InnoDB-based PARTITION-ed
table as there HA_PRIMARY_KEY_REQUIRED_FOR_POSITION enabled.

fixed by introducing new handler::rnd_pos_by_record() method to be
used for random record-based positioning

mysqldump --skip-events --all-databases dumped data of the mysqld.event table,
and during the restoration from this dump events were created in spite
of the --skip-events option.

The mysqldump client has been modified to ignore mysql.event table data
in case of --skip-events options.

Discovered a bug while working with backup. Since it is possible to execute a statement in a pre/post statment clause that can return a result, we need to test for that and free it.

statement.

c++config.h now has the following code:
// For example, <windows.h> is known to #define min and max as macros...
#undef min
#undef max

So, our defines in my_global.h are undefined when <new> header
is included.

Move definitions of min()/max() to the end of my_global.h.
