OK, here is a patch that makes those changes.

The only uncertainty I have is with the the use of the TCVN conversion
routine names, e.g.:

SELECT CONVERT('foo' USING tcvn_to_utf_8);

I assume this is the same as:

SELECT CONVERT('foo', 'WIN1258', 'UTF8');
and
SELECT CONVERT('foo', 'TCVN', 'UTF8'); -- alias usage

So, why would people use the routine name? Both forms are documented.
The first one with USING does not accept aliases, while the others do.

I think this should be renamed to win1258_to_utf_8. However, this would
be an incompatibility. We should mention it in the release notes.

Other than that the other conversion files were already named fine, e.g.
ascii_to_utf_8 (no UNICODE), however it is utf_8 and not utf8. I am
unsure how to handle these.
