cmdrewrite: add a utility function to make sure note is of valid format
Upcoming patches will add support to store a note on various evolution related
commands by storing that in obsmarker. Since the obsmarker metadata field can't
store things above 255 bytes, this patch introduces a function which will be
used to make sure note is under 255 bytes and does not contain newlines. We
don't want notes to be multilines.
