MDEV-22726: Add check that one can't change general or slow log to a transactional engine
the commit subject should be in one line (and I personally only put one space between the MDEV number and the text, not a colon, because the subject length is quite limited to waste it on pretty delimiters that don't add any meaningful information)

No, sorry, you cannot add new error messages in 10.2. Or 10.3 or 10.4. Because adding a new error message to anything below 10.5 would mean that 10.5 error numbers will shift and we aren't allowed to do it for compatibility reasons. The typical workaround is to use my_print_error(ER_something_else, "Only non-transactional Aria table can be used for logging"); (with the appropriate error number, MYF(0), etc)

What about InnoDB? Or RocksDB? Or any other transactional engine?
