Patches: improved URI handling

I've just hacked a couple of patches that fill gaps in Apache's
URI manipulation, sufficient to construct HTTP requests for external
resources.  May I submit these for inclusion?

It's mainly an APR patch, but it's also a small httpd patch to fill
a parsed_uri from information in a request_rec

Here are the additional function definitions in the Header files:

1. httpd patch to protocol:

/**
 * fill_parsed_uri: fill in fields available in request that parse_uri
 * may have left null.  Saves making too many special cases when
 * using the parsed_uri.
 * @param r The current request
 * @deffunc void ap_parse_uri(request_rec *r, const char *uri)
 */
AP_CORE_DECLARE(void) ap_fill_parsed_uri(request_rec *r) ;


2. apr-util patch to apr_uri

/**
 * Resolve an already-initialised but possibly-relative URL
 * against a given base URL.
 * @param p The pool to allocate out of
 * @param base The base to resolve against
 * @param uptr The apr_uri_t to resolve
 * @return An HTTP status code
 */
APU_DECLARE(int) apr_uri_resolve_relative(apr_pool_t *p,
                                          const apr_uri_t *base,
                                          apr_uri_t *uptr);

/**
 * Parse a given URI, fill in all supplied fields of a apr_uri_t struct.
 * If the given URI is relative, then resolve it using a supplied base
 * @param p The pool to allocate out of
 * @param base The base to resolve against
 * @param uri The uri to parse
 * @param uptr The apr_uri_t to fill out
 * @return An HTTP status code
*/
APU_DECLARE(int) apr_uri_parse_relative(apr_pool_t *p,
                                        const apr_uri_t *base,
                                        const char* uri,
                                        apr_uri_t* uptr);
