Change the registered filter name to XLATEOUT (from XLATE).

Set up the context in the filter in case the filter was inserted via
AddOutputFilter.

Provide a temporary hack to avoid having the module and core both
insert the output translation filter.  For now, code
"CharsetOptions NoImplicitAdd" in a container with "AddOutputFilter."

Make a few cosmetic changes (e.g., rename the mis-named
xlate_register_filter routine).
