WL#1689 "Map OPTIMIZE TABLE to ALTER TABLE for InnoDB"

Browse Source 
exactly it's mapped to "ALTER TABLE t; ANALYZE TABLE t;"


sql/ha_innodb.cc:
  ::optimize() now returns "try ALTER and then analyze" instead of only analyze.
sql/handler.h:
  new code to say "try alter and analyze".
sql/mysql_priv.h:
  as we may now use mysql_alter_table() internally to ::optimize we must prevent it from talking to the client.
  New function mysql_recreate_table() which is the same as ALTER TABLE t;
sql/sql_parse.cc:
  the big block removed here is moved into mysql_recreate_table().
sql/sql_table.cc:
  In mysql_admin_table(): if the handler returns HA_ADMIN_TRY_ALTER,
  we close the table, recreate it, then open it and analyze it.
  This is currently used only for OPTIMIZE TABLE of an InnoDB table.
