//
// Standard schemes are subject to URL canonicalization and parsing rules as
// defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1 available
// at http://www.ietf.org/rfc/rfc1738.txt
//
// In particular, the syntax for standard scheme URLs must be of the form:
//
// <scheme>://<username>:<password>@<host>:<port>/<url-path>
//
// Standard scheme URLs must have a host component that is a fully qualified
// domain name as defined in Section 3.5 of RFC 1034 [13] and Section 2.1 of RFC
// 1123. These URLs will be canonicalized to "scheme://host/path" in the
// simplest case and "scheme://username:password@host:port/path" in the most
// explicit case. For example, "scheme:host/path" and "scheme:///host/path" will
// both be canonicalized to "scheme://host/path".
//
// For non-standard scheme URLs only the "scheme:" component is parsed and
// canonicalized. The remainder of the URL will be passed to the handler as-is.
// For example, "scheme:///some%20text" will remain the same. Non-standard
// scheme URLs cannot be used as a target for form submission.
//
// Register a custom scheme handler factory for the specified |scheme_name| and
// optional |host_name|. Specifying an NULL |host_name| value for standard
// schemes will match all host names. The |host_name| value will be ignored for
// non-standard schemes. Set |is_standard| to true (1) to register as a standard
