5.12 OPTIONS *
HTTP defines an OPTIONS method that can be sent with an asterisk option like
"OPTIONS *" to ask about options from the server and not a specific URL
resource. https://tools.ietf.org/html/rfc7230#section-5.3.4
libcurl as it currently works will always sent HTTP methods with a path that
starts with a slash so there's no way for an application to send a proper
"OPTIONS *" using libcurl. This should be fixed.
I can't think of any other non-slash paths we should support so it will
probably make sense to add a new boolean option for issuign an "OPTIONS *"
request. CURLOPT_OPTIONSASTERISK perhaps (and a corresponding command line
option)?
