Function regex_match_pub 

pub fn regex_match_pub(value: &str, pattern: &str, ci: bool) -> bool

Public aliases so the SQL SELECT engine matches patterns with EXACTLY the same code NQL does.

Two implementations of LIKE or of the regex subset would be two chances for the SQL surface and the NQL surface to disagree about the same operator on the same data — and a filter that disagrees with itself is the silent-wrong-row class this engine keeps having to remove.
