fn resolve_module_specifier(

) -> Result<ServoUrl, UrlParseError>

The following module specifiers are allowed by the spec:

• a valid absolute URL
• a valid relative URL that starts with “/”, “./” or “../”

Bareword module specifiers are currently disallowed as these may be given special meanings in the future. https://html.spec.whatwg.org/multipage/#resolve-a-module-specifier
