Windows Server 2003 and the beta for Vista.

XP and it's service pack only have MS_ENH_RSA_AES_PROV_PROTO which is missing
just those hash algorithms compared to the server 2003 version.

I notice that the current code in xmlsec uses MS_ENH_RSA_AES_PROV_PROTO, not
MS_ENH_RSA_AES_PROV, and even defines it if not found.

I'd like to test if the two implementations of that provider have a mapping for
each other's name. If not the case, that means trouble for Windows Server 2003
users trying to make use of AES in xmlsec with MS CAPI provider.
