Enhancing our old regex library to support all modern features and
multiple charsets is complex and bug-prone work.

I don't see why we should bother doing it, when there are plenty of
regex libraries available.

There's PHP's mb_regex, there's prce, and many others too. We'd better
just pick one that works better for MariaDB, and put it instead of
Henry Spencer's library.
