BUG#4335 - one name can be handler open'ed many times. Reworked the HANDLER functions and interface. Using a HASH to store information on open tables that survives FLUSH TABLE. HANDLER tables alias names must now be unique, though it is allowed in 4.0 to qualify them with the database name of the base table.
