xlator: make 'xlator_api' mandatory

* Remove the options to load old symbol.
* keep only 'xlator_api' symbol from being exported using xlator.sym
* add xlator_api to all the xlators where its missing

NOTE: This covers all the xlators which has at least a test case
to validate its loading. If there is a translator, which doesn't
have any test, then we should probably remove that from codebase.
