rpcrt4: Pass the interface identifier to the lower-level context handle routines for context handles with the strict flag set.

widl: Output calls for the new versions of the marshalling and unmarshalling routines for server context handles.

This needs to be done to match the call to NdrContextHandleInitialize 
and because we default to using strict context handles.

ole32: get_moniker_for_progid_display_name should fallback to using IClassFactory to get IParseDisplayName if getting it directly fails.

msi: OriginalDatabase is the fully-expanded path to the original package if the package is local and installed from the command line.

msi: If the package is a URL, the OriginalDatabase property should be the URL and the DATABASE property should be the path to the local temporary package.

The RPC runtime could use some of the parameters, expecting them to be 
initialised.

svchost: Add a FIXME for an undocumented function (SvchostPushServiceGlobals) that some native services expect to be called by native svchost.
