* Returns: {string|undefined} Returns `name` if the certificate matches,
`undefined` if it does not.
* Returns: {string|undefined} Returns a subject name that matches `name`,
or `undefined` if no subject name matches `name`.

Checks whether the certificate matches the given host name.

If the certificate matches the given host name, the matching subject name is
returned. The returned name might be an exact match (e.g., `foo.example.com`)
or it might contain wildcards (e.g., `*.example.com`). Because host name
comparisons are case-insensitive, the returned subject name might also differ
from the given `name` in capitalization.
