            losing it's .MYD

When OPTIMIZE TABLE is completed it attempts to rename temporary
file to original name. This step may fail on windows when a file
is opened. As a result data file might be deleted and optimized
copy of file (table_name.MYD) remains.

This situation is handled properly by my_delete_allow_opened, so
use it instead of my_delete when attempting to rename a file on
windows.

No suitable test case for this bug.

            causes incorrect duplicate entries

Keys for BTREE indexes on ENUM and SET columns of MEMORY tables
with character set UTF8 were computed incorrectly. Many
different column values got the same key value.

Apart of possible performance problems, it made unique indexes
of this type unusable because it rejected many different
values as duplicates.

The problem was that multibyte character detection was tried
on the internal numeric column value. Many values were not
identified as characters. Their key value became blank filled.

Thanks to Alexander Barkov and Ramil Kalimullin for the patch,
which sets the character set of ENUM and SET key segments to
the pseudo binary character set.
