beorn7 9bb7ab43cd labels.Matcher: Improve regexp and allow escaping
This addresses a number of issues:

- It was impossible to include a literal '"' or a line break in the value.
- It was impossible to include '=', '~', or '!' in the value.
- It was not validated if the label name is valid.
- It was not validated if the value is valid UTF-8.
- No whitespace was allowed around the operator.
