Existing configuration parsing functions (e.g. http_options() in http.c) know how to parse two-level configuration variable names. We would like to exploit them and parse something like this: [http] sslVerify = true [http "https://weak.example.com"] sslVerify = false and pretend as if http.sslVerify were set to false when talking to "https://weak.example.com/path". Introduce `urlmatch_config_entry()` wrapper that: - is called with the target URL (e.g. "https://weak.example.com/path"), and the two-level variable parser (e.g. `http_options`); - uses `url_normalize()` and `match_urls()` to see if configuration data matches the target URL; and - calls the traditional two-level configuration variable parser only for the configuration data whose <url> part matches the target URL (and if there are multiple matches, only do so if the current match is a better match than the ones previously seen).
