The errors in the line buffer and tokenizer now have diagnostics. The line number is trivial to keep track of due to the line buffer, but the column index requires quite a bit of juggling, as we pass successively trimmed down buffers to the internals of the parser. There will probably be some column index counting problems in the future. Also, handling the diagnostics is a bit awkward, since it's a mandatory out-parameter of the parse functions now. The user must provide a valid diagnostics object that survives for the life of the parser.
