compileHostRules

Compiles host patterns into a predicate. A pattern is a host name (example.com), a host name with a port (example.com:8443) or a wildcard for subdomains (*.example.com, which does not match example.com itself). A pattern without a port matches any port. Matching is case-insensitive.
