Added Created_tmp_disk_tables variable to mysqld.

To make it possible to reliably dump and restore tables with TIMESTAMP(X) columns, MySQL now reports columns with X other than 14 or 8 to be strings.

Changed sort order for latin1 as it was before MySQL 3.23.23. Any table that was created or modified with 3.23.22 must be repaired if it has CHAR columns that may contain characters with ASCII values greater than 128!

Fixed small memory leak introduced from 3.23.22 when creating a temporary table.

Fixed problem with BDB tables and reading on a unique (not primary) key.

Restored the win1251 character set (it's now only marked deprecated).
