InternetCanonicalizeURLA / W - Missing some flags?

[Chris Howe]

I noticed a FIXME cropping up in the logs when working on EQ2, related to
InternetCanonicalizeURL not fully parsing the flags that it is called with.
Looking a bit closer, it offloads the grunt work to UrlCanonicalize anyway,
and the missing flags seem to have analogs defined for UrlCanonicalize to
use, and adding support for them makes the message go away: no problems that
I can see, either.

However, I seem to be having trouble running the test for wininet, as it
just hangs for me (before I made the alterations, that is)... would somebody
care to check that the attatched patch is correct?
