Refactored a number of engines to have correct init/deinit. Added pass support for "data" from plugin to plugin generic init to use memory location.

plugin/daemon_example/plug.in:
  Switched the plug.in type (corrected)
sql/handler.h:
  Added data pointer to use for engines.
sql/sql_plugin.cc:
  Passing plugin to generic handlers to allow them to add data to "data"
storage/archive/ha_archive.cc:
  Refactored. Now uses less logic for startup/shutdown.
storage/csv/ha_tina.cc:
  Refactored init/deinit to use less code.
storage/example/ha_example.cc:
  Refactored example to show correct behavior for init/deinit.
storage/example/ha_example.h:
  Removed unneeded references to methods that do not need to be implemened.
storage/federated/ha_federated.cc:
  Refactored to use less code and startup/shutdown correctly.
