// Register a custom scheme. This function should not be called for the built-
// in HTTP, HTTPS, FILE, FTP, ABOUT and DATA schemes.
//
// If |is_standard| is true (1) the scheme will be treated as a standard
// scheme. 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:
// <pre>
// [scheme]://[username]:[password]@[host]:[port]/[url-path]
// </pre> 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". The origin of a standard scheme URL
// is the combination of scheme, host and port (i.e., "scheme://host:port" in
// the most explicit case).
//
// 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.
//
// If |is_local| is true (1) the scheme will be treated as local (i.e., with
// the same security rules as those applied to "file" URLs). Normal pages
// cannot link to or access local URLs. Also, by default, local URLs can only
// perform XMLHttpRequest calls to the same URL (origin + path) that
// originated the request. To allow XMLHttpRequest calls from a local URL to
// other URLs with the same origin set the
// CefSettings.file_access_from_file_urls_allowed value to true (1). To allow
// XMLHttpRequest calls from a local URL to all origins set the
// CefSettings.universal_access_from_file_urls_allowed value to true (1).
//
// If |is_display_isolated| is true (1) the scheme will be treated as display-
// isolated. This means that pages cannot display these URLs unless they are
// from the same scheme. For example, pages in another origin cannot create
// iframes or hyperlinks to URLs with this scheme.
//
// This function may be called on any thread. It should only be called once
// per unique |scheme_name| value. If |scheme_name| is already registered or
// if an error occurs this function will return false (0).
