Formatting and docs corrections for logical decoding output plugins.

Make the typedefs for output plugins consistent with project style;
they were previously not even consistent with each other as to layout
or inclusion of parameter names.  Make the documentation look the same,
and fix errors therein (missing and misdescribed parameters).

Back-patch because of the documentation bugs.
