* Combine a base URL and a relative URL to produce a new

*
* This function implements the "absolutize" algorithm from
* the RFC3986 specification for URLs.
*
* This function supports multi-byte characters with the UTF-8 encoding,
* per the URL specification.
*
* Parameters:
* baseUrl the absolute base URL.
*
* url the relative URL to convert.
*
* Return values:
* An absolute URL that combines parts of the base and relative
* URLs, or FALSE if the base URL is not absolute or if either
* URL cannot be parsed.
