helpers: refactor and optimize urlify_issues

Avoid parsing the configuration and compiling regexps every time a string is
processed.

Instead, the configuration is parsed once and turned into a function that apply
the compiled regexps in a chain.

A next iteration can perhaps run them in parallel and integrate with the
general urlify machinery.
