tests: add glob matching for unified tests This adds a " (glob)" marker that works like a simpler version of (re): "*" is converted to ".*", and "?" is converted to ".". Both special characters can be escaped using "\", and the backslash itself can be escaped as well. Other glob-style syntax, like "**", "[chars]", or "[!chars]", isn't supported.
