This is the first step in improving the error messages produced while parsing. The `line` and `column` information of `Source` has been moved to `Source::Location`. `Source::Range` has been added that contains a `Location` interval - allowing error messages to highlight the full region of the error. The `File` information provides an optional file path, and pre-splits the content into lines. These lines can be used to print the full line containing an error. This CL contains a few temporary changes that help split up this work, and to ease integration with Tint.
