Only output code for non-object interfaces in client and server
generation and convert the while loops into for loops.

Avoids test failure when the current day happens to be the 31st...

Fix some string length calculations that didn't account for the
different sized characters with Unicode.

- Implement add disposition in CertAddCertificateContextToStore,
  rather than in each store.
- Add a few more tests.

These tests currently fail in Wine.

(based on a patch by Byeong-Sik Jeon).

ConfigureNotify and related events should only be processed when
posted messages are selected. There's no need to handle MappingNotify
if keyboard events are not selected.

Try to be a bit more strict when checking for resource mapping in
exception handler (and prevent some exceptions while in exception
handler).

Replace memcmp with IsEqualIID macro that doesn't require a size
parameter and remove the unneeded brackets to give more compact and
more readable code.

Tests with native show that during COM calls posted messages aren't
retrieved other than COM calls so change the PeekMessage parameters in
CoWaitForMultipleHandles to duplicate this.

Try to retrieve messages that are COM calls first in
CoWaitForMultipleHandles before retrieving other types.

Put the PeekMessage call of CoWaitForMultipleHandles into a separate
function so that the order and type of the messages retrieved can be
customised in the future.
