Fix #2614

[dcooper16]

Describe your changes

Currently compare_server_name_to_cert() only indicates whether the server's host name matches a wildcard name in the certificate. So, it does not indicate if the certificate includes a wildcard name that does not match the server's host name. As a result, if a certificate includes the names "api.sub.example.tld" and "*.api.sub.example.tld," then a wildcard certificate warning will be issued for host names such as www.api.sub.example.tld, but not for api.sub.example.tld.

This commit changes compare_server_name_to_cert() to indicate whether the certificate is a wildcard certificate in addition to providing information about how the certificate matches the server's host name. Functions that use this function's response are then changed to extract the information they need (matching or wildcard) from the return value.
