Sanitizing HTMLSerializer allows invalid attributes by converting to ASCII
While looking at a change in bug 492931, bz noticed that mozSanitizingHTMLSerializer::IsAllowedAttribute() is returning false positives by lossily converting the UTF-16 attribute name to ASCII. Simply switching from the lossy conversion to a lossless UTF-16 to UTF-8 conversion should fix this, the extra non-ASCII characters making the attr_bag->Has() call fail. This patch applies on top of my patch in bug 492931, but it could easily be separated out.

Sorry Ed, here's the patch split off from bug 492931. Carrying forward review+ as the refactoring itself is trivial and bz already looked at it once. Boris, let me know if that's not okay.
