build_full_url (const char *uri, const char *base_uri)

Synopsis

If the specified URI string does not start with a URL schema or a directory delimiter, we add the path of the base URI, and return the resulting full URI. This is provided as a freshly- allocated string which the caller must free using mem_free() when finished. If the specified URI is already a full URI, returns a fresh copy of that URI.
