advapi32: The lpcbSecurityDescriptor parameter to RegGetKeySecurity isn't optional, so don't complicate the code by treating as though it is.

This reverts commit 31876695.

Change the return value from BOOL to NTSTATUS so that we can return the 
exception code to the caller.

kernel32/tests: Fix the time tests when 'Automatically adjust clock for daylight saving changes' has been unset.

Make the test of the return value of wait_for_incoming_data less strict.

Since there is no in or out, or other information necessary for
remoting, all of the interfaces can only used locally, so declare them
all as local.

This could happen if proxy_manager_get_remunknown returns S_FALSE, so 
fix the check of the return code to match that below.

ole32: Fix a potentially confusing combination of conditional and bitwise or operators by adding extra brackets.
