This patch changes the mechanism by which the client enables a plugin. Instead of using INSERT IGNORE to reload a plugin library, it now uses REPLACE INTO. This allows users to load a library multiple times replacing the existing values in the mysql.plugin table. This allows users to replace the symbol reference to a different dl name in the table. Thus permitting enabling of multiple versions of the same library without first disabling the old version. A regression test was added to ensure this feature works.
