The use of a regular expression allows multiple rewrite rules to be

Addd mxs::pcre2_substitute that is a more C++-friendly version of
mxs_pcre2_substitute to make. This makes string replacement a lot easier

MaxScale directory is called maxscale-uncrustify.sh, which uses

Several filters use a match-or-ignore logic with two regular
expressions when filtering queries. This commit adds a convenience
function for this task. Also adds a convenience function for reading
several regular expression parameters at once, compiling them and
saving the code while checking for errors.
Also, use the new functions in QLA and CCR filters.
