Thomas Preud'homme df284c0ecf Regex: Make "match" and "sub" const member functions ... Summary: The Regex "match" and "sub" member functions were previously not "const" because they wrote to the "error" member variable. This commit removes those assignments, and instead assumes that the validity of the regex is already known after the initial compilation of the regular expression. As a result, these member functions were possible to make "const". This makes it easier to do things like pre-compile Regexes up-front, and makes "match" and "sub" thread-safe. The error status is now returned as an optional output, which also makes the API of "match" and "sub" more consistent with each other. Also, some uses of Regex that could be refactored to be const were made const.
